OrcaSlicer Calibration Masterclass: Pressure Advance — Which Test Do You Trust? (Part 3)

Sun, 09 Aug 2026 00:00:00 GMT

Part 3 of the OrcaSlicer Calibration Masterclass is up, and this one’s about Pressure Advance — the setting responsible for those blobby corners and gapped lines that show up whenever your printer speeds up or slows down mid-print.

▶️ Watch on YouTube

What Pressure Advance Actually Fixes

Pressure Advance compensates for the lag between your extruder motor moving and the filament actually pushing out of the nozzle. When your printer accelerates, that lag shows up as bulging. When it decelerates, it shows up as gaps. Dial in the right PA value and the hot end pushes a consistent amount of filament out regardless of speed — sharp corners, no blobs, no gaps.

OrcaSlicer gives you three ways to find that value: the PA Tower, the PA Line test, and the PA Pattern test. I ran all three back to back on my Sovol SV08 (direct drive) to see how much they actually agree with each other.

The Three Tests, Compared

Test	Value	Notes
PA Tower	0.056	Classic test, built into most slicers/firmware. Look for the sharpest corner.
PA Line	0.054	Fastest to read — look for the most consistent line.
PA Pattern	0.050	Newest test in OrcaSlicer, but I trusted this one least — the lines weren’t as clean on my print.

The three tests didn’t agree exactly, which is normal — they’re measuring the same thing with different amounts of visual noise. I ended up going with 0.055, splitting the difference between the Tower and Line results and discounting the Pattern test since I wasn’t confident in the read.

Skip the Manual Math

Once you’ve measured your test print, you still need to convert that measurement into an actual PA value — that’s the part most people get stuck on or get wrong by eyeballing it. I built a calculator that does this for you: plug in your start value, increment, and measured distance, and it gives you the number to paste into OrcaSlicer.

Setting the Value in OrcaSlicer

Once you’ve got your number:

Open your filament profile and hit Edit
Scroll down and enable Pressure Advance
Enter your calculated value
Save the profile

That’s it — no firmware flashing, no macros, just a filament setting.

Which Test Should You Use?

If you only have time for one test, run the Line test — it’s the fastest to print and read. If you want a second opinion (recommended, since no single test is perfect), add the Tower. I’d hold off on trusting the Pattern test alone until you’ve got some practice reading it — it’s more prone to misreads than the other two, at least in my experience.

For the full methodology straight from the source, OrcaSlicer’s own wiki has a good reference: OrcaSlicer Pressure Advance Calibration.

What’s Next

Part 4 covers Adaptive Pressure Advance — a more dynamic method that OrcaSlicer now recommends over the static single-value approach we used here. I’ll show you how to calculate and test it.

Calibrating the Sovol SV08 Temp Tower in OrcaSlicer

Sun, 12 Jul 2026 00:00:00 GMT

A couple of weeks ago, I upgraded the hotend on my Sovol SV08 to the MicroSwiss FlowTech, but the machine has essentially been gathering dust because I haven’t had a chance to run through the proper calibrations. Today, it’s time to get this printer rolling again.

I’m currently running the latest version of OrcaSlicer. While I’ve typically started my calibrations with Flow Ratio in the past, a deeper look at the official OrcaSlicer calibration guide recommends tackling the tests in the exact order they are listed in the menu. We are going to follow that outline, starting right at the top: the Temperature Tower.

Why the Temp Tower Matters

The OrcaSlicer wiki highlights that temperature calibration is arguably the single most critical factor for overall print quality. The nozzle temperature directly impacts the viscosity of your filament.

Too low: You risk under-extrusion, poor layer adhesion, and stringing.
Too high: You invite filament degradation, clogging, severe stringing, and sagging on your overhangs.

One great feature in OrcaSlicer is that the temp tower automatically scales its size to match your nozzle diameter, ensuring all the overhangs and bridging features are correctly proportioned for your setup.

Pre-Flight Slicer Settings

Before generating the tower for my Silk PLA, I set up an initial profile to follow standard parameters. I use percentages for my line widths so that if I swap nozzles later, the settings dynamically adjust.

I also made a few specific tweaks to the profile:

Switched the wall generator from Arachne to Classic (running inner-outer instead of inner-outer-inner).
Enabled Z-contouring.
Crucial Step: Navigated to the Others tab and set the Brim to Auto. Because the temp tower is tall and has a very small footprint, it desperately needs that brim to hold it securely to the build plate.

Interpreting the Results

I ran the standard PLA tower, which starts at the hottest temperature (230°C) at the bottom and steps down by 5 degrees every section until it reaches 190°C at the top.

If you are looking at your own tower and find a range that looks great (for example, between 195°C and 205°C), the general rule of thumb is to select the temperature right in the middle (200°C). However, if you plan on pushing high flow rates and faster printing speeds, leaning toward the higher end of that range will help maintain proper flow.

When evaluating my Silk PLA, the tower was honestly a bit brutal to look at. I inspected the overall layer adhesion, the severity of the stringing, and the sharpness of the corners. The sides varied, but looking closely at the overhangs and corner defects, the 205°C to 210°C range produced the cleanest results with the least stringing.

Final Profile Adjustments

I decided to settle on 210°C as my standard printing temperature for this filament. To ensure a solid foundation and better bed adhesion, I bumped my initial layer temperature up slightly to 215°C, and increased my heated bed to 60°C.

With the temperature dialed in, the SV08 is one step closer to being fully tuned. In the next post, we’ll move down the OrcaSlicer calibration menu and tackle the Max Volumetric Speed test.

OrcaSlicer 2.4 Beta: K2 Plus CFS Sync & Z-Contouring Deep Dive

Sun, 14 Jun 2026 00:00:00 GMT

Overview

Welcome back to the Minimal 3DP workbench. Today we are diving into the massive changes introduced in the OrcaSlicer 2.4 Beta release.

A quick personal note before we get to the technical data: I have not been posting as much lately due to struggles with anxiety and depression. I have gotten help and am doing much better. If you are struggling, please seek help; it benefits not only you, but everyone around you.

Now, let’s break down exactly what the 2.4 Beta brings to the table, where the current bugs lie, and how to optimize your hardware to take advantage of these new computational tools.

The Creality K2 Plus: CFS Filament Synchronization

One of the most highly anticipated features in this beta is direct network synchronization for the Creality K2 Series CFS, the Color Filament System. For farm operators and enthusiasts using the K2 Plus daily, this is a massive workflow improvement.

However, because this is an early beta, the implementation is not without friction. During my testing, the initial synchronization attempt failed to connect.

Diagnostic Fix: Bypassing the Port Error

If you experience a connection timeout when trying to sync your CFS to OrcaSlicer, try the following steps:

Navigate to the device connection settings.
Remove the specific port number from the end of your IP address string.
Alternatively, use the Browse function to allow OrcaSlicer to auto-detect the Creality printer on your local network.
If it still fails, restart OrcaSlicer. A fresh launch resolved the handshake issue in my environment.

⚠️ The Hardware Bridge: Unlocking the K2 Plus

Software synchronization is fantastic, but it cannot bypass a mechanical flow restriction. Early adopters of the K2 Plus are reporting significant reliability issues regarding the extruder mechanisms, the multi-color filament feeding systems, and frequent false-positive clog errors. To permanently resolve these design flaws and unlock the volumetric flow required for high-speed coreXY printing, I highly recommend upgrading your stock toolhead.

Upgrade to a High-Flow Hotend

Smoothing the Top Surface: Z-Contouring

Once your hotend is mechanically capable of laying down consistent plastic, you can leverage OrcaSlicer 2.4’s new Z-Contouring feature.

This setting directly addresses the stair-step effect that plagues curved or shallow-sloped 3D prints. During a recent community project printing fairy-themed mushroom caps, the standard slicing resulted in highly visible topological rings on the dome.

Enabling Z-Contouring essentially acts as anti-aliasing for your Z-axis. It dynamically alters the layer height and line width along shallow curves to mathematically smooth the transition between steps.

Real-World Testing Results

Printing the mushroom caps side-by-side, one stock and one with Z-Contouring enabled at a minimum Z-height of 0.05 and an angle threshold of 35 degrees, the difference is notable. While not injection-molded perfection, the stair-step effect is significantly less pronounced to the naked eye.

Beta Warnings and Known Bugs

If you are running a production print farm, do not deploy this beta to your primary slicing workstations yet. Always back up your profiles and settings before installing any alpha or beta releases.

During my Z-Contouring testing, I discovered a critical slicing bug:

The “Unexpected Number of Instances” Error: If you have Z-Contouring enabled and attempt to slice a build plate with multiple instances of an object, such as filling the bed with magic wands, the slicer will throw an error.
The Result: The slicing engine will freeze, and clicking the slice button will do nothing. You must disable Z-Contouring to successfully slice plates with high instance counts in this current build.

Klipper Configuration Optimization

If you have upgraded your hotend, remember that you must recalibrate your PID settings in your Klipper configuration. Add or update the following block in your printer.cfg via your central Klipper dashboard:

[extruder]
# Run PID_CALIBRATE HEATER=extruder TARGET=220 to generate exact values
# Example tuned parameters for high-flow hotends:
control = pid
pid_kp = 26.213
pid_ki = 1.304
pid_kd = 131.721

The important part is not the example values themselves; it is the process. Run the PID calibration command for your exact hotend, thermal mass, and target temperature, then save the generated values back to printer.cfg.

Wrap Up

OrcaSlicer 2.4 Beta is a big step forward for K2 Plus operators and anyone chasing cleaner curved surfaces. CFS network synchronization removes a real workflow pain point, and Z-Contouring gives us a new mathematical tool for fighting visible layer stair-stepping.

The catch is that this is still beta software. The CFS sync path still has handshake quirks, and Z-Contouring currently breaks multi-instance slicing. Pair the software upgrade with good hardware fundamentals, keep your Klipper config tuned, and treat this release like a lab tool rather than a production workhorse.

Stay minimal.

Mastering Klipper: Updating Deprecated Firmware on MCU and EBB

Sun, 12 Apr 2026 00:00:00 GMT

If you updated Klipper in Mainsail or Fluidd and suddenly see a warning about deprecated code on your MCU and EBB board, this guide is for you.

The short version: updating Klipper on the host does not automatically update firmware on your physical boards. You need to recompile and flash both your toolhead board and your mainboard so protocol versions stay in sync.

Hardware in This Walkthrough

Host: BTT CB1 or Raspberry Pi
Mainboard: BTT Manta M8P V1.1
Toolhead board: EBB2209 CAN
CAN bootloader: Katapult (formerly CanBoot)

Why the Warning Happens

Klipper has two parts:

Host software running on Linux
Firmware running on each microcontroller board

When the host updates but board firmware stays old, Klipper reports protocol mismatch/deprecated code until everything is aligned.

Before You Start

SSH into your host.
Back up your current config files.
Keep your current board UUIDs handy from printer.cfg.
Have physical access to the toolhead board in case you need a reset.

Phase 1: Update the EBB Toolhead (CAN)

1. Build Klipper Firmware for the EBB

cd ~/klipper
make menuconfig
make clean
make

In menuconfig, choose options that match your exact EBB model and bootloader settings.

2. Stop Klipper Before Flashing

sudo service klipper stop

3. Flash Over CAN

Use your EBB UUID from printer.cfg. If needed, discover devices with canbus_query first.

python3 ~/klipper/scripts/canbus_query.py can0
python3 ~/katapult/scripts/flashtool.py -i can0 -u <your-ebb-uuid> -f ~/klipper/out/klipper.bin

If the board is not detected or flash fails, do a double-tap reset on the EBB to force bootloader mode, then rerun the flash command.

Phase 2: Update the Mainboard (BTT Manta M8P)

If your Manta is acting as a USB-to-CAN bridge, your menuconfig settings matter a lot. Wrong settings can break CAN communication.

Use this reference profile for M8P V1.1:

Setting	Selection
Micro-controller	STMicroelectronics STM32
Processor model	STM32G0B1
Bootloader offset	8KiB bootloader
Clock Reference	8 MHz crystal
Communication interface	USB to CAN bus bridge (USB on PA11/PA12)
CAN bus interface	CAN bus (on PD12/PD13)

Then compile and flash with your normal M8P method (SD card, DFU, or your existing maintenance workflow), and confirm the new firmware boots cleanly.

Verify Everything

Start Klipper again:

sudo service klipper start

Then refresh Mainsail/Fluidd and confirm:

Deprecated code warnings are gone
MCU and CAN stats populate normally
No recurring protocol shutdown errors

If errors remain, verify USB/CAN visibility from the host:

lsusb

When It Is Not Firmware Anymore

If you repeatedly see protocol shutdowns or flash instability even after clean reflashes and reset attempts, hardware failure is possible (especially from heat/stress over time).

Potential replacement paths:

EBB2209 CAN Board: go.minimal3dp.com/ebb-can
BTT Manta M8P V2.0: go.minimal3dp.com/btt-manta

If this walkthrough helped, save it in your printer maintenance notes so the next Klipper update cycle takes minutes instead of hours.

Making 3D Prints Look Professional | OrcaSlicer 2.3.2 Final

Sun, 29 Mar 2026 00:00:00 GMT

Overview

Hey, this is Mike from Minimal 3DP, and today we are wrapping up our OrcaSlicer 2.3.2 series. The release candidate phase is officially over, and the stable 2.3.2 release is finally here.

In this fourth and final part of our series, we are moving away from structural engineering and focusing entirely on aesthetics. If you want your 3D prints to look like professionally manufactured, injection-molded parts, this is the update you’ve been waiting for. We are going to look at Fixed Angle Ironing, Structured Fuzzy Skin, and a seam alignment feature I completely missed for years. Let’s go ahead and get started.

The Hardware Bridge: Consistent Extrusion for Textures

Software textures and ironing only look good if your physical extrusion is perfectly consistent. If your hotend is pulsing or your extruder gears are skipping, no amount of slicer tuning will save your top surfaces. I’m testing these aesthetic upgrades on my K2 Plus ecosystem to ensure we have a rock-solid baseline.

Printer: Creality K2 Plus & CFS
Printer (Standalone): Creality K2 Plus
Filament: eSUN Fire Engine PLA+

Transparency Note: Some of the links in this post are affiliate links. If you go through them to make a purchase, I will earn a small commission (which helps support M3DP!). You will not pay a penny more.

1. Fixed Angle Ironing (Fixing Tiger Stripes)

Standard ironing algorithms dynamically change the ironing direction based on the longest dimension of the top layer. While this saves time, it creates “tiger striping”—where light reflects differently off varying sections of the flat top surface, making it look patchy and distinctly 3D printed.

The 2.3.2 Fix: OrcaSlicer 2.3.2 introduces a Fixed Ironing Angle setting. By forcing the nozzle to iron in the exact same vector (e.g., 45 degrees) across the entire top surface, the plastic grain aligns perfectly. The result is a smooth, uniform reflection of light.

To test your own top surfaces, you can use this Top Surface Ironing Test model.

2. Structured Fuzzy Skin (Voronoi, Perlin, Billow)

Older versions of fuzzy skin simply jittered the nozzle randomly. It often looked like a printing error or wet filament rather than an intentional design choice. OrcaSlicer 2.3.2 introduces mathematically generated noise patterns to turn standard plastic into premium textures.

Voronoi Noise: Creates an aggressive, geometric, “leather-like” cracking effect. Perfect for automotive parts or tactical grips.
Perlin Noise: Generates a smooth, continuous, flowing texture suitable for organic shapes.
Billow Noise: Produces a clustered, “cloud-like” texture.

Klipper Configuration for Surface Finishes

When ironing top layers, the extruder is pushing a microscopic amount of filament (typically around 10% flow). To prevent blobs or uneven pressure during these micro-movements, ensure your Klipper configuration is optimized for precise extrusion and smooth cornering.

# Minimal 3DP Surface Finish Baseline (printer.cfg)
[printer]
# Tuning square_corner_velocity prevents the toolhead from dwelling
# and leaving blobs at the edges during ironing passes
square_corner_velocity: 5.0

[extruder]
# Ensure your pressure advance is perfectly tuned for your specific filament
# to handle the rapid start/stops of Structured Fuzzy Skin
pressure_advance: 0.04
pressure_advance_smooth_time: 0.040

3. The True Value of Premium Parts (FDM Cost Calculator)

Now that your prints feature professional surface finishes, you can confidently sell them to commercial clients. But to run a profitable farm, you must know your exact margins.

I built the Minimal 3DP FDM Cost Calculator to help you factor in machine wear, transaction fees, and exact material usage.

OrcaSlicer v2.3.2 Final Stable Release

Dialing in Multi-Material & Smoother Infill | OrcaSlicer 2.3.2 (Part 3)

Sun, 22 Mar 2026 00:00:00 GMT

Overview

Hey, this is Mike from Minimal 3DP. Today we are taking a closer look at OrcaSlicer 2.3.2 with three focus areas: multiline infill, spiral Z-hop, and bulletproof wipe towers.

In older slicer builds, multi-material printing can look incredible until a prime tower collapses halfway through, taking hours of print time down with it. Even with aggressive tuning, wipe towers are still fragile when you mix materials like PETG and PLA.

The latest OrcaSlicer 2.3.2 release candidates include several software-level changes designed to reduce those failures. Let us break down what matters and what to enable.

Watch on YouTube: https://youtu.be/4Pr5vlJvTvk

The Hardware Bridge: Multi-Material Testing

Software tweaks only work if your hardware can keep up. For this test set, we are printing K2 Plus parts for an upcoming video and using that platform as the baseline for all 2.3.2 multi-material checks.

Printer: Creality K2 Plus & CFS
Printer (Standalone): Creality K2 Plus
Filament: eSUN Fire Engine PLA+

Transparency Note: Some links in this post are affiliate links. If you use them to make a purchase, I may earn a small commission that supports M3DP. You do not pay extra.

1. The Infill Rebuild: No More Grinding

In previous versions, multiline infill patterns like Triangles or Cubic created harsh line intersections. As the nozzle crossed previously laid paths, you would hear micro-vibrations and grinding. Over time, those repeated impacts can weaken internal structure quality.

In OrcaSlicer 2.3.2 preview mode, those transitions are rebuilt with rounded corners. Rounded path transitions keep volumetric flow more consistent and reduce abrupt extruder start-stop behavior at intersections.

The practical result is less filament grinding and smoother internal motion, especially useful with softer materials like PLA+ and PETG.

2. Bulletproof Wipe Towers (PETG/PLA Interfaces)

PETG support interfaces for PLA are popular because the materials separate cleanly. The downside is that they also struggle to bond on the prime tower, which can lead to tower delamination and mid-print failure.

OrcaSlicer 2.3.2 adds interface-specific controls to improve tower survivability:

Interface temperature boosts: Temperature is raised on key interface layers to improve PETG/PLA tower adhesion.
Extra pre-extrusion: Nozzle pressure is built before tower engagement to reduce under-extrusion on critical early layers.
Flushing notches: The nozzle is wiped before flushing to reduce blob dragging across the part.

3. The True Cost of Multi-Material Prints

These new wipe tower controls can save long prints, but there is still a cost problem: prime towers consume a lot of filament.

To quantify that waste, use the Minimal 3DP FDM Cost Calculator:

Calculate Your True Print Costs

If you are tired of typing filament and machine costs into every run, the Operator tier on Patreon unlocks Pro calculator features with saved profile data:

Join the Operator Tier on Patreon ($5/mo)

This lets you store local energy rates and machine data so you can evaluate multi-color jobs quickly before you commit print time and material.

4. Spiral Z-Hop Optimization & Klipper Config

Standard Z-hop can force abrupt Z-axis movement. On lower-end controller boards, large amounts of micro-movement can overload the planner buffer and cause stutters or blobs.

Spiral Z-Hop in OrcaSlicer 2.3.2 introduces adaptive slicing resolution (roughly 4 to 24 segments), producing smoother motion commands that are easier for controllers to process.

If you run mainline Klipper, validate your retraction and Z-axis limits so the machine can execute rapid hop transitions reliably:

# Minimal 3DP Z-Hop & Retraction Baseline (printer.cfg)
[firmware_retraction]
retract_length: 0.8
retract_speed: 40
unretract_extra_length: 0.0
unretract_speed: 40

[stepper_z]
# Ensure max_z_velocity and max_z_accel can support rapid spiral hops
max_z_velocity: 15
max_z_accel: 100

Final Takeaway

OrcaSlicer 2.3.2 makes meaningful progress on three real production issues:

Cleaner multiline infill transitions
More reliable PETG/PLA wipe tower behavior
Smoother Z-hop motion delivery for constrained controllers

These are practical quality-of-life improvements, but they do not remove the economics of multi-material waste. Pair the new slicer controls with cost tracking so your print decisions stay both reliable and profitable.

Fixing Wavy Walls & Sagging Bridges: OrcaSlicer 2.3.2 Flow Tuning

Sun, 15 Mar 2026 00:00:00 GMT

Overview

Even after extensive tuning, such as running resonance compensation, 3D printed parts can still exhibit visual artifacts. Common issues include sagging bridges and “wavy” or “bulging” outer wall textures, which persist despite standard calibration efforts. OrcaSlicer 2.3.2 (Release Candidate) introduces highly granular software adjustments to address these specific hardware-extrusion bottlenecks.

This technical guide documents the process of utilizing structure-specific flow ratios and high-density bridging to achieve injection-molded surface qualities.

The Hardware Bridge: Extrusion Consistency

Software flow tuning is only effective if your hardware maintains consistent volumetric pressure. For these tests, we rely on the Creality K2 Plus to ensure baseline stability, utilizing eSUN PLA+ to accurately gauge the effect of flow modifications.

Test Printer: K2 Plus
Test Filament: eSUN Fire Engine PLA+

Affiliate Notice: Purchasing through these links supports the Minimal 3DP ecosystem at no additional cost to you.

Granular Flow Control: Eliminating the Ripple Effect

Previous slicer iterations relied heavily on a global flow rate multiplier. OrcaSlicer 2.3.2 allows users to independently adjust the flow ratio for almost every distinct print structure (outer walls, inner walls, first layer, etc.).

The Problem

When utilizing a uniform flow rate, the volume required for optimal layer adhesion on inner walls or infill often causes slight over-extrusion on the outer perimeters, resulting in a visible “ripple effect” or wavy interface on thin walls.

The Calibration Fix

By navigating to the Quality tab and checking the “Set other flow ratios” box in the Walls and Surfaces section, we can decouple these values.

Establish Baseline: Determine your optimal global flow rate. In our K2 Plus testing, the baseline flow was 0.98, whereas OrcaSlicer defaults to 1.0.
Isolate Outer Walls: Decrease the flow rate strictly for the “Outer Wall” parameter.
Result: Lowering the flow rate specifically on the outer perimeter eliminates the wavy texture, resulting in a visually smoother face and sharper corners without compromising the structural integrity of the infill.

High-Density Bridging: Structural Overhauls

Bridging unsupported geometry traditionally involves stretching filament across a gap. OrcaSlicer 2.3.2 introduces a setting designed to increase the density of the bridging surface, placing the extruded lines closer together to form a solid sheet.

Testing Methodology

Using the Unsupported Bridge Experiments Model, we observed the following:

Untuned Bridging: Lines are spaced far apart, lacking adhesion, resulting in gaps and severe sagging.
High-Density Enabled (Flow = 1.0): The top surface solidifies significantly, but requires further flow tuning.
High-Density + Altered Flow: The release notes advise using a lower flow rate paired with higher density. Testing with an erroneously high flow rate produced poor top surfaces. The ideal configuration requires matching the high density (closer lines) with a proportional drop in bridging flow to prevent material pooling.

Klipper Configuration Considerations

When pushing high-density bridging and rapid flow transitions on high-speed machines, your Klipper extruder settings must be configured to handle sudden spikes in max_extrude_cross_section, especially if overlapping perimeters occur.

# Minimal 3DP Extruder Baseline (printer.cfg)
[extruder]
# Ensure this value accommodates high-density bridging calculations
max_extrude_cross_section: 5.0

# Ensure your pressure advance is tuned for the specific filament
# to prevent bulging during the rapid decelerations of bridging
pressure_advance: 0.04
pressure_advance_smooth_time: 0.040

OrcaSlicer v2.3.2 Beta 2: The Data-Driven Slicer Overhaul

Sat, 07 Mar 2026 00:00:00 GMT

The community has been waiting for a major update to the OrcaSlicer interface, and v2.3.2 Beta 2 delivers. This release isn’t just about small bug fixes; it represents a fundamental shift toward real-time monitoring and granular control—perfect for those of us who view our 3D printers as precision engineering tools.

In this deep dive, we’re exploring how these new UI changes and technical features can revolutionize your workflow.

[!WARNING]

A Note on Beta Safety

Before you dive into the new features, remember that this is beta software. To avoid the “Foundation of Sand” issue where your profiles are lost during an update, back up your configuration folder immediately.

Pro Tip: In OrcaSlicer, go to Help > Show Configuration Folder. Zip that entire directory and save it to a safe location.

1. The Improved G-Code Viewer: Real-Time Flow Analysis

One of the most significant updates in v2.3.2 is the integration of an improved G-code viewer, ported directly from PrusaSlicer.

For the “Engineering Enthusiast,” this is a game-changer. You can now analyze your prints in real-time with specific views for:

Actual Speeds: Visualize exactly how fast your toolhead is moving at every point of the model.
Volumetric Flow Rates: Identify potential bottlenecks before you even start the print.

2. Fine-Tuning with “Set Other Flow Ratios”

OrcaSlicer now allows you to set individual flow ratios for nearly every feature of your model. This is critical for achieving “Gold Standard” quality.

If your base flow is even slightly off, your entire print can fail. By isolating flow ratios for different parts of the model, you gain the granular control needed for high-performance engineering prints.

3. Modular Printer Agents: Multi-Material Sync

The new Modular Printer Agent Architecture allows for seamless synchronization with multi-filament units like the AMS (Quitty, Snapmaker, Armor Turtle box). This architecture ensures your slicer and your hardware are always in sync, reducing the friction often found in multi-material workflows.

4. Quality of Life & UI Improvements

Compact Printer Interface: The new UI lists your printer, nozzle diameter, and bed type in a more informative, streamlined layout.
Wi-Fi Connectivity: Management has moved to a more visually pleasing location above the printer settings.
New Profiles: Dozens of new printer and filament profiles have been added, ensuring your hardware is supported out of the box.

What’s Next?

In the next part of this series, we’ll be doing a technical deep dive into bridging and further testing these new flow rates.

From Chromebook to Dev Machine - Setting up a Modern GIS & Python Stack

Wed, 04 Mar 2026 00:00:00 GMT

Chromebooks are no longer just for web browsing. With the built-in Linux subsystem, they are now capable of running a professional development environment. This guide walks you through setting up a “Gold Standard” stack: VS Code, Git/GitHub via SSH, Python (via uv), and Containerized PostGIS (via Podman).

1. Enabling the Engine

First, you need to unlock the ability to run Linux apps on your ChromeOS device.

Open Settings > Advanced > Developers.

Turn on the Linux development environment.

Once the terminal opens, update your package list:

sudo apt update && sudo apt upgrade -y

2. Professional Git & VS Code Setup

Don’t settle for the web-based editors; get the full desktop experience.

Install Git: sudo apt install git -y.

VS Code: Download the .deb file (x64 for Intel/AMD, ARM64 for mobile chips) from the official site. Right-click it in your Files app and select Install with Linux.

SSH Keys: Generate a key for secure GitHub access:

ssh-keygen -t ed25519 -C "your_email@example.com"
cat ~/.ssh/id_ed25519.pub

Copy that output and add it to your GitHub Settings > SSH and GPG keys.

3. The Modern Python Stack: uv and just

Standard pip and make are fine, but for speed and clarity, we use uv (an extremely fast Python manager) and just (a modern command runner).

Install the Tools

# Install uv
curl -LsSf https://astral.sh/uv/install.sh | sh

# Install just
sudo apt install just -y

The Workflow

With these installed, you can initialize a project with uv init and use a justfile to automate your chores. Instead of typing source .venv/bin/activate && python main.py, you simply type just run.

4. Running PostGIS with Podman

Since GIS work requires a database, we use Podman. It is a great “rootless” alternative to Docker that runs smoothly inside the Chromebook’s Linux container.

Install: sudo apt install podman -y

Alias it: Add alias docker=podman to your .bashrc so your existing scripts work without changes.

Spin up PostGIS:

podman pull postgis/postgis

5. Putting it All Together: The Genesis Template

The ultimate goal is to clone a “Gold Standard” template (like the genesis-template) and be ready to code in seconds.

# Clone your template
git clone git@github.com:your-username/your-template.git
cd your-template

# Sync dependencies and start the stack
uv sync
just start

Your Chromebook is now a full-fledged GIS development workstation, running a FastAPI backend, a PostGIS database, and a high-speed Python environment.

Key Chromebook Pro-Tips:

Port Forwarding: When you run a server on port 8000, ChromeOS automatically maps it. You can access it at localhost:8000 in the Chrome browser.
Storage: If you plan on running multiple containers, go to your Linux settings and increase the disk size to at least 20–30GB.

Enhancing Print Strength: A Deep Dive into the GeekDetour BrickLayers Implementation

Fri, 27 Feb 2026 00:00:00 GMT

If you’ve been following the channel, you know I’m a big fan of the BrickLayers concept. By offsetting layer lines—much like a bricklayer offsets joints in a wall—we can significantly improve the mechanical strength of 3D prints, particularly along the Z-axis.

Recently, I updated the Minimal 3DP Web Tool to include a second, more “hefty” implementation: the GeekDetour version. While the original Tenager Technologies script is excellent for its simplicity, the GeekDetour version offers granular control for power users.

However, because this script is more complex, your slicer settings need to be dialed in correctly to avoid errors. Here is everything you need to know to get the most out of this new implementation.

The Core Requirement: “Classic” Wall Mode

The most critical setting for the GeekDetour implementation is your Wall Generation mode.

Modern slicers like OrcaSlicer and PrusaSlicer often default to “Arachne” for wall generation. While Arachne is great for variable line widths, it can confuse the BrickLayers script, which relies on consistent pathing to calculate the offsets.

The Fix: Switch your Wall Generator to “Classic” before exporting your G-code. This ensures the script can accurately identify and shift the perimeters without creating pathing conflicts.

Key Setting Differences: GeekDetour vs. Tenager

When using the GeekDetour version via the Minimal 3DP web app, you’ll notice a few default behaviors that differ from the original version:

Starting Layer: GeekDetour defaults to starting the effect at Layer 3. This ensures your first few layers (the foundation) remain untouched for maximum bed adhesion.
Extrusion Multiplier: The script uses a slightly smaller default extrusion multiplier. In my testing on the Creality K2 Plus, this helped manage the “bulging” that can sometimes occur when layers are shifted, though it can lead to slightly more stringing.
Z-Hop Integration: This implementation handles travel moves differently to account for the shifted paths. If you see “wispy” stringing, don’t panic—this is a known trade-off for the increased structural integrity.

How to Process Your Files

You no longer need to struggle with Python environments or terminal commands. I have containerized this logic so you can run it directly in your browser:

Slice your model in OrcaSlicer or PrusaSlicer (remember: Classic walls!).
Export the G-code to your desktop.
Upload to the Minimal 3DP BrickLayers Tool.
Select “GeekDetour” from the implementation dropdown.
Download and print.

Verification

I’ve personally verified the output by running the web-processed G-code against local Python script results using AI analysis. The movement commands are identical; the only difference is the metadata. Your prints will be just as strong as if you ran the script manually.

BrickLayers Without the Code: Get 3D Printed Brick Wall Strength in Your Browser

Sat, 17 Jan 2026 00:00:00 GMT

If you have been 3D printing for a while, you have likely heard of the “BrickLayers” technique. Originally popularized by CNC Kitchen, this post-processing method significantly increases the structural integrity of printed parts by offsetting layers—just like a real brick wall.

The engineering is sound, but for many makers, the execution has been a barrier. Until now, using BrickLayers required installing Python, managing dependencies, and running local scripts.

Today, I am removing that friction. I have updated the workflow to make it accessible to everyone through a free, browser-based tool.

The Theory: Why “Brick Wall” Patterns Matter

To understand why this tool is valuable, we have to look at how FDM 3D printing handles stress.

In a standard print, layers are stacked directly on top of one another. When stress is applied perpendicular to these layer lines, the print is prone to delamination—basically, the layers rip apart because the failure point runs in a straight line down the part.

The BrickLayers concept borrows from masonry. By alternating the perimeter starts and creating an offset pattern (a “running bond”), you interrupt that direct line of stress. The interface between layers becomes complex and interlocking, making the part significantly stronger without changing the material.

The Problem: The Python Barrier

While the result of BrickLayers is fantastic, the process was designed for engineers and developers. Running a Python script on your local machine to post-process G-code isn’t difficult if you code, but it is a hassle if you just want to print a strong part.

I decided to revisit this technique with a focus on usability. I wanted to bridge the gap between the engineering concept and the everyday printing workflow.

The Solution: The Minimal 3DP Web Tool

I have ported the BrickLayers logic into a web application. This means:

No Python installation required.
No command line usage.
Secure processing: The tool streams your G-code through our secure server for processing and immediately sends it back. No files are ever saved to a disk or database.

You can access the tool here: Minimal 3DP BrickLayers Tool

Data Verification: Does it Slow Down Printing?

A common concern with altering G-code is the impact on print time. Does a more complex toolpath ruin your efficiency?

I ran a comparison using a standard Benchy to verify the data:

Standard Print: 29 minutes, 49 seconds
BrickLayers (Python Script): 30 minutes, 14 seconds
BrickLayers (Web Tool): 30 minutes, 14 seconds

The Result: You are looking at a difference of roughly 25 seconds (less than a 2% increase) for a part that benefits from structurally superior layer adhesion.

How to Use It

Slice your model as you normally would.
Save the G-code file.
Go to the BrickLayers Web Tool.
Load your G-code.
Let the browser process the file and download the new version.

If you have been reluctant to try this technique because you didn’t want to configure a development environment, give the web app a try. It is free to use, and it brings engineering-grade wall strength to your standard slicer workflow.

Step-by-Step Sovol SV08 Build: From Box to Klipper in Under 2 Hours

Sat, 10 Jan 2026 00:00:00 GMT

Is the Sovol SV08 the best entry point for a large-format CoreXY?

I realize the SV08 has been on the market for a bit now, but I recently decided to pick one up. Why? Because the price-to-performance ratio has hit a sweet spot that is hard to ignore. I grabbed this unit for under $500—shipped directly from a US warehouse via AliExpress—and frankly, for that price, it creates a very interesting proposition for anyone looking to get into the Voron ecosystem without the 40-hour build time.

In the first installment of this new series, I take the SV08 from the shipping box to a functional Klipper instance in under two hours.

Unboxing & Logistics: The AliExpress Surprise

There is often a stigma about ordering large hardware from AliExpress, but you can find some incredible deals if you look carefully. I ordered this specific unit from a seller stocking it in a US warehouse. The result? It arrived incredibly fast—less than a week—and the box was in perfect shape.

Packaging is tight and well-thought-out. If you’ve been hesitant about shipping damage on these larger printers, my experience here was reassuring.

The Build: Weekend Warrior Friendly

This is not a “kit” in the traditional Voron sense. It is a pre-assembled module that requires final integration.

If I wasn’t filming the process for the channel, I honestly believe I could have had this machine assembled in one hour. Even taking my time, the entire process took about two hours. It is surprisingly straightforward—the gantry comes mostly pre-assembled, and the wiring is largely managed for you.

However, having the right tools makes a difference. I used my go-to drivers for this build, which saves a massive amount of frustration compared to the little Allen keys included in the box.

Hex Head Allen Wrench Set

High-quality drivers that prevent stripped screws. A must-have.

Critical Warning: Watch the Top Panel

While the build is solid, there is one specific hardware quirk you need to know about immediately to avoid damaging your new machine.

Do not pick up the SV08 by the top frame.

Unlike a Voron 2.4, where the skirt (bottom) is often the weak point, the SV08 has a very thin aluminum top section. It is not 2020 extrusion; it’s a thinner profile. If you try to lift the printer by the top bar, you risk bending the frame.

Instead, use the handles built into the side of the plastic case. It’s the opposite of what we are used to with other CoreXY builds, but it’s crucial for the longevity of this machine.

The Roadmap: Roots and Upgrades

Out of the box, the SV08 runs a fairly stock version of Klipper. It boots up, it prints, and it’s a solid machine right from the start.

But this video is just the baseline. My plan for this series is to treat the SV08 not as an appliance, but as a platform. In upcoming posts and videos, we are going to:

Root the machine to gain full control over the Klipper instance.

Upgrade the cooling and hotend for better performance.

Push the speeds to see what this frame can actually handle.

Check out the full build video below to see exactly how it comes together.

Quantifying Risk: A Data-Driven Look at 3D Printing Air Quality

Thu, 01 Jan 2026 00:00:00 GMT

For me, the conversation around 3D printing usually revolves around speed, calibration, and cost. But recently, the focus shifted to something far more critical: the air I breathe while I create.

Following my open-heart surgery in October, I became acutely aware of the environmental factors in my workspace . I work in a 200-square-foot office, and because I close the door to record, I realized I was essentially printing in a sealed box . This personal realization sparked a deep dive into the invisible byproducts of Fused Deposition Modeling (FDM) .

Beyond Anecdotes: The Data

Rather than relying on forum hearsay, I took a rigorous approach. I utilized Notebook LM to synthesize data from 56 different scientific articles regarding emissions . The research highlights two invisible risk factors every maker should understand:

Ultrafine Particles (UFPs): Microscopic pieces of plastic and debris floating in the air .
Volatile Organic Compounds (VOCs): Gases released during the melting process, particularly from petroleum-based filaments like ABS and ASA .

Surprisingly, the research indicates that even PLA—often considered the “safe” option—can release VOCs equivalent to ABS depending on the brand, pigments, and additives used . In many cases, PLA is not just plant-based material; it has so many additives that it can cause risks .

Real-World Testing with the K2 Plus

To test the theory against reality, I set up a comprehensive sensor array using the Creality K2 Plus printing ASA . I placed air quality monitors inside the printer’s enclosure, directly outside near a HEPA filter, in the hallway, and downstairs .

The results were telling. The sensors demonstrated that a simple enclosure can act like a fireplace screen, keeping an estimated 95% of particles and gases contained . However, my testing also revealed a critical workflow error. In an attempt to clean the printer glass with alcohol, I inadvertently caused a massive spike in VOC readings, proving that sometimes our cleaning habits can be just as impactful as the printing itself .

Practical Mitigation

I found several mitigation strategies derived from the scientific research that I now implement:

Enclosures: This is the first line of defense.
The “Cool Down” Rule: Letting a print sit for 10 to 20 minutes after completion significantly reduces the release of particles when you open the door.
Filtration: I recommend getting a HEPA filter that is oversized for your office to exchange the air roughly six times an hour.

For a complete breakdown of the data and to see the sensors in action, check out the full video.

Don't Panic: Rolling Back Firmware on the Creality K2 Plus 3D Printer

Mon, 29 Dec 2025 00:00:00 GMT

If you are reading this, you probably did exactly what I did last night: I wasn’t paying attention, saw a green update button, and just pressed it .

Normally, updates are a good thing. But in this case, I immediately regretted it. I was trying to record a video and needed my K2 Plus for its enclosed chamber, but the moment I installed the new firmware, I had nothing but errors and couldn’t print a single thing . Specifically, it wouldn’t even get to the preheating stage before crashing out with stepper timing errors .

Since I don’t use Creality Print, it took me a while to figure out how to manually roll back the firmware to a stable version . If you are stuck in the same boat, here is the step-by-step process to get your machine running again without using their slicer software.

Step 1: Finding the “Hidden” Firmware

The first step is grabbing the firmware image from the Creality website. This gets a little confusing because of how they organize their files.

Go to the Creality website and navigate to the K2 Plus in the categories section .
Look at the firmware list. You might notice the version listed isn’t the previous one you were using—it might be several versions behind .
The Trick: Click the “plus” sign next to “Old Versions” . Surprisingly, you will often find newer firmware hidden in this folder.
Download the image file for the version you want to restore .

Step 2: Preparing Your USB Drive

This is the most critical step. If you don’t format the drive correctly, the printer won’t read it.

Insert a USB drive into your computer.
Open your disk utility (I used a Mac, but right-clicking ‘Format’ on Windows works the same way) .
Format the drive as exFAT . It is vital that you choose exFAT; otherwise, the bootloader likely won’t pick it up.
Once formatted, drag and drop the downloaded image file onto the USB drive .
Eject the drive safely .

Step 3: The “Upgrade” Process

Now we head over to the printer.

Turn the printer OFF .
Insert the USB drive into the port on the right-hand side of the machine .
Turn the printer back ON .
The screen will boot up and ask if you want to “Upgrade” to the version on the stick. Even though we are downgrading to an older version, hit Upgrade .

Note: The system might estimate this will take hours, but in my experience, it installs much faster than that . Just be aware that rolling back firmware will wipe any custom config files you had, so you will lose your customizations .

Step 4: Recalibration

Once the installation is complete, the machine will reboot.

Remove the USB drive .
Since the machine thinks it has a fresh install, you need to recalibrate .
Run the start detection/self-check to ensure your bed tension and leveling are correct .

Once that finishes, you should be clear to slice a file and send it to the printer to verify everything is working .

If you want to see exactly how I formatted the drive or navigated the menu, you can watch the full walkthrough here:

Hopefully, this saves you the frustration I dealt with last night!

The Hidden Cost of Open Source: Why I’m Launching the Minimal 3DP Patreon

Fri, 26 Dec 2025 00:00:00 GMT

In the domain of desktop manufacturing, we obsess over tangible costs. We calculate the price per kilogram of filament, analyze the depreciation of a nozzle, or measure the energy consumption of a heated bed. [cite_start]However, my research into optimization techniques highlights a critical variable often missing from the equation: Time[cite: 6].

[cite_start]For the past few years, Minimal 3DP has operated to bridge the gap between “Appliance Consumers” and “Engineering Enthusiasts”[cite: 2]. We’ve explored Klipper firmware, dissected OrcaSlicer profiles, and pushed prosumer hardware to its absolute limits. [cite_start]But as the market undergoes the “Great Bifurcation”—where machines diverge into locked-down appliances or complex open-source projects—the burden of configuration has shifted entirely to you, the user[cite: 2].

Open source is free, but your time is not.

The Problem: Calibration Hell

The current ecosystem often forces a binary choice: pay a premium for a “walled garden” ecosystem or spend hours scrolling through forums to find a configuration that doesn’t result in a layer shift.

In my strategic analysis of the channel, I identified a critical inefficiency. [cite_start]You aren’t coming to Minimal 3DP just for entertainment; you are coming for data[cite: 1]. You need the verified parameters that turn a chaotic build into a reliable tool. You need optimization without the trial-and-error cycle that kills throughput.

From Text Prompt to Tangible Print: Using Tripo 3.0 to Commemorate Recovery

Thu, 18 Dec 2025 00:00:00 GMT

By Mike Wilson

As many of you know, this past October got a little personal for me. I underwent heart surgery, and I’ve spent the last few months focused on recovery. I’m finally reaching the point where I feel like myself again—I even started physical therapy this week.

To commemorate this journey and mark getting back on my feet, I wanted to create a project that felt significant: a realistic, 3D-printed human heart.

Usually, a project like this would involve hunting down a specific STL or spending hours sculpting in Blender. Instead, I used this as an opportunity to test a new AI tool: Tripo 3.0.

Note: A big thank you to Tripo 3.0 for sponsoring this project. As always, while they are supporting the channel, the opinions and testing results below are entirely my own.

What is Tripo 3.0?

Tripo 3.0 is an AI generation tool capable of creating 3D models from simple text prompts or reference images. The developers claim it offers the “cleanest, sharpest, and most detailed geometry” in the AI 3D space.

That is a bold claim. We are used to AI models requiring hours of mesh repair before they are printable. However, after using it for this project, I have to admit—the topology was shockingly clean.

The Workflow: Ideation to Slicer

For this project, I tested two different generation methods to see which produced the best “printable” result.

Method 1: Text-Only Prompt

I started with a simple command: “Create a model of a realistic human heart.”

Result: It generated a highly detailed, anatomically correct heart. However, it was just the organ itself—no base, no stand. Great for anatomy, harder to display.

Method 2: Text + Image Reference

Next, I uploaded a reference image from Wikipedia and combined it with the text prompt.

Result: This was the winner. The AI not only generated the heart but interpreted the context of the image to include a display stand.

The Verdict: Both models generated in about two minutes. The level of surface detail—specifically the veins popping out from the surface—was stunning. For a “set it and forget it” tool, the quality was surprisingly high.

From Cloud to Build Plate

Getting AI models out of the browser and into the physical world is usually where the headache starts. Here is exactly how I handled the files for anyone looking to replicate this workflow.

1. Exporting

Tripo offers OBJ, STL, and 3MF exports.

[!TIP] Pro Tip: Use the 3MF format.

Why? In my testing, the STL files exported at a very small scale, requiring manual resizing. The 3MF files imported into the slicer at a reasonable, printable size immediately.

2. Slicing (OrcaSlicer)

I brought the model into OrcaSlicer. Even though the geometry was clean, organic shapes always need support help.

Scale: For the version without the stand, I scaled it to 150%. For a massive heart, I tested scaling up to 300% (though that would have taken forever to print).
Supports: I utilized Slim Tree Supports (Organic).
Adhesion: I added an Outer Brim to ensure the small contact points on the bottom didn’t detach.

3. The Print

Printer: FDM Printer
Time: The stand version took roughly 1 hour 21 minutes. The larger, stand-less version took 4 hours 27 minutes.
Post-Processing: The supports snapped off cleanly. There was some minor scarring on the back of the stand-less model where it lay on the build plate (mostly due to my orientation choice, not the model geometry), but the display side was pristine.

Beyond Hobbyist Tools

While I used this for a personal commemorative piece, the toolset inside Tripo 3.0 is definitely aiming at the professional crowd.

Segmentation: I tested this on a robot model. The software automatically broke the single mesh into distinct parts (arms, legs, head), allowing you to edit or merge specific components.
Retopology: For those of you using Blender or ZBrush, the generated topology is workable, not the usual “soup of triangles” we see from photogrammetry or older AI tools.

Final Thoughts

I printed a realistic thyroid years ago for my wife after her surgery (she found it romantic, I promise), and this project felt like a similar closing of a chapter for me.

If you are looking to generate artistic models, figurines, or organic shapes without needing to master digital sculpting, this is the easiest workflow I have found to date.

Creality K2 Plus Upgrade Series: Installing the Micro Swiss FlowTech Hotend

Fri, 28 Nov 2025 00:00:00 GMT

The Creality K2 Plus has established itself as a flagship machine, but for the “Engineering Enthusiast,” stock hardware is rarely the end of the road. In the latest installment of the K2 Plus Upgrade Series, I tackle a critical component swap: replacing the stock hotend with the Micro Swiss FlowTech system equipped with the CM2 High Flow Hardened Steel nozzle.

This guide covers the technical specifications, a direct weight comparison, and the step-by-step installation process to help you decide if this upgrade is right for your rig.

The Hardware: FlowTech & CM2 Nozzle

The primary motivation for this upgrade is flow performance and durability. While browsing upgrade paths, I secured the Micro Swiss FlowTech hotend, pairing it specifically with the CM2 High Flow nozzle.

It is important to distinguish between the nozzle options available for this ecosystem. Micro Swiss offers standard plated nozzles and generic high-flow versions, but the CM2 stands out because it utilizes hardened steel. This is a critical distinction for users printing with abrasive engineering materials like carbon fiber filled filaments.

Key Specifications

The CM2 boasts a flow rate of 50 cubic millimeters per second, ensuring the hotend can keep up with the rapid kinematics of the K2 Plus.

Bench Test: Stock vs. Micro Swiss

Before installation, I performed a side-by-side comparison of the OEM equipment versus the Micro Swiss replacement.

Visual Differences

Stock K2 Plus Hotend

Micro Swiss FlowTech Hotend

Visually, the Micro Swiss unit features significantly larger and more complex cooling fins, suggesting improved thermal management. Interestingly, the heating element section appears slightly smaller on the FlowTech compared to stock.

Weight Comparison

In terms of mass—a critical factor for input shaping calibration—the difference is negligible:

Component	Weight
Stock Hotend	44 grams
Micro Swiss FlowTech	45 grams

This 1-gram difference confirms that the Micro Swiss is effectively a drop-in replacement that won’t drastically alter the toolhead’s mass characteristics. This means your existing input shaping profiles will remain largely valid.

Installation Guide

Step 1: Removal

The process begins by carefully unplugging the two connectors attached to the main breakout board. These connectors can be tight, so caution is required to avoid damaging the board headers.

Once disconnected, remove the two retaining screws located near the bottom plate of the hotend assembly.

Step 2: Wiring Orientation

When seating the new FlowTech hotend, proper orientation is vital:

The unit features an indent that must face the front of the printer
Ensure the wires are routed toward the front
Position the brass wire at the top

Getting this orientation correct prevents issues with thermistor readings and ensures proper cooling fan operation.

Step 3: Securing the Unit

With the hotend seated, reinstall the mounting screws:

Loosely thread the front screws first
Then secure the top screws
Final tightening once everything is aligned

This sequence ensures the unit is properly aligned before final tightening and prevents cross-threading or misalignment.

Calibration & Testing

Hardware installation is only half the battle. After powering on the machine, I verified that the thermistor was reporting ambient temperature correctly before attempting to heat the nozzle.

Required Calibration Steps

Because the mass and flow characteristics have changed slightly, users should run the full calibration suite:

PID Tune: To ensure stable temperatures
Input Shaping: To account for the slightly different weight distribution
Auto-Leveling: To adjust for any Z-offset changes

The ASA Benchy Test

To validate the install, I printed a 3DBenchy using ASA filament.

Results:

✅ Extrusion quality: Excellent, consistent flow throughout
✅ Layer adhesion: Perfect interlayer bonding
⚠️ Bed adhesion: Lifting at the chimney (common with ASA on stock surface)

While the print suffered from a bed adhesion issue—a common struggle with ASA on stock build surfaces—the extrusion quality itself was excellent. The body of the Benchy looked “phenomenal,” confirming that the FlowTech is delivering consistent extrusion.

Stop Guessing: Introducing the FDM Filament Recommendation Engine

Fri, 21 Nov 2025 16:00:00 GMT

One of the biggest problems I have in my 3D printing journey is simply trying to remember which filament is best for which scenario. If I need a UV-resistant filament for an outdoor part, or if I need to know if a specific engineering-grade material is actually printable on my current setup, digging through PDF Technical Data Sheets (TDS) takes forever.

To solve this, I’ve developed a new app: the FDM Filament Recommendation Engine.

You can watch my full video introduction here:

The Solution: A Data-Driven Filament Finder

Link to Tool: filament.minimal3dp.com

The goal of this application is to let you sort, query, and filter through over 40 different materials to find the one that fits your specific project needs.

I developed this by analyzing various manufacturer TDS records, but I know those aren’t always perfectly accurate. To validate the data, I also cross-referenced peer-reviewed journal articles. I utilized AI to help extract and organize this massive amount of data into a usable format.

Key Features and Updates

For those of you who saw the early version of this tool, I’ve made several updates based on my own testing and user feedback:

Simplified Strength Metrics

I originally had three different choices for “strength,” but they were all telling me the same thing. I have simplified this to just General Strength and Compressive Strength to make the data easier to read.

Printability Scoring

You can filter by “Printability.” If you back the slider off to an 8, you’ll see familiar materials like PLA and PETG. If you look at engineering materials like PC or ASA, you’ll see that score drop significantly—reflecting the real-world difficulty of printing those materials.

Comparison Tool

This is probably the most useful feature. You can select multiple filaments (for example, UV-resistant materials like ASA, PC, and others) and hit “Compare.” This gives you a side-by-side look at their cost score, heat compatibility, and stiffness.

Processing Data

I’ve added information on whether a material can be annealed—the process of heating the print after printing to make the material stronger and more dimensionally stable.

Feedback Welcome

I have added a feedback form to the site. If you have a better source of data than the TDS sheets or journal articles I have used, please feel free to submit it. My goal is to make this a complete repository of knowledge for us to use.
