How to Use HueForge Filament Calculator
Enter your base layer height (e.g. 0.16mm or 0.20mm) and detail layer height (e.g. 0.08mm or 0.04mm).
Select your 4 filament colors in sequence (e.g. Black -> Blue -> Red -> White).
Input known Transmission Distance (TD in mm) for each filament spool.
Calculate exact slicer layer swap heights and optical color blending depths.
What is the HueForge Filament Calculator?
A specialized optical calculator for multi-color filament painting (HueForge) that calculates layer step heights and filament opacity transitions.
Formula Used
• Layer Z Height (mm) = Base Layer (mm) + (Layer Index × Step Height (mm))
• Color Opacity Factor = Layer Thickness (mm) / Transmission Distance (TD mm)
Real-World Example
Base layer = 0.16mm, step = 0.08mm. Color 2 starts at layer 8: Swap Z height = 0.16 + (7 × 0.08) = 0.72mm.
Accuracy and Limitations
Accurate results require knowing the true TD of your filament spool brand (calibrated via a step test).
Who It Is For
HueForge artists, Bambu Lab AMS creators, and multi-color 3D printing enthusiasts.
Frequently Asked Questions
What is Transmission Distance (TD) in HueForge?
Transmission Distance (TD) is the thickness in millimeters required for a filament color to become completely opaque. Low TD filaments (e.g., Black TD ~0.5) block light quickly, while high TD filaments (e.g., White TD ~5.0) allow underlying colors to blend through.
How do you calculate HueForge color swap heights?
Color swap height is determined by adding base layer height to the cumulative count of thin layers (0.08mm) designated for that specific filament tone.
