I'm excited to share a new feature I've been working on for PrusaSlicer for the past couple of hours that makes creating multi-color prints with the MMU3 WAY easier and more fun! Auto-Colorization lets you apply gorgeous color patterns to your models with just a few clicks - no manual painting required!
🚀 What is Auto-Colorization?
Tired of spending hours manually painting triangles for multi-material prints? This new addition to the MMU Segmentation tool automatically applies color patterns to your models. Choose from several algorithms, tweak the settings, and watch your model transform!
⭐ Key Features
Five Pattern Algorithms:
🌈 Height Gradient: Smooth vertical color transitions (think rainbow vases!)
⭕ Radial Gradient: Circular patterns radiating from center
🌀 Spiral Pattern: Eye-catching spiral effects
🎲 Noise Pattern: Organic, random-looking patterns using Perlin noise
⚡ Optimized Changes: Smart color bands that minimize tool changes
Complete Control:
✅ Choose which MMU3 filaments to use (1-5)
✅ Set percentage-based color distribution
✅ Pattern-specific tweaks (gradient direction, spiral pitch, noise scale, etc.)
✅ Preview before applying
✅ One-click application
🎯 Perfect For:
Decorative objects with stunning patterns
Gradient transitions without the tedium
Quick color testing different combinations
Highlighting features on functional prints
Anyone who wants beautiful prints without artistic skills!
🔧 How to Use:
Load model → MMU Segmentation tool
Open "Auto-colorize" section
Pick pattern + adjust settings
Preview → Apply when happy!
💭 Why I Made This
Manual MMU painting is a pain. Hours of clicking tiny triangles just to get decent color separation. I wanted everyone to create beautiful multi-color prints regardless of artistic ability or patience level!
