OBJ to Multi-Material 3MF

About This Tool

Convert textured OBJ files (from Meshy.ai or similar AI generators) into multi-material 3MF files ready for color 3D printing.

Features:

  • Parses OBJ + MTL + PNG texture from ZIP exports
  • Samples colors from texture at UV coordinates
  • Uses k-means clustering to reduce to 4-8 printable materials
  • Auto-scales to proper size and centers on build plate
  • Generates Bambu Studio compatible multi-material 3MF

Note: After opening in Bambu Studio, you'll need to configure your printer (must support AMS) and map the colors to your physical filament spools. This is normal for multi-material printing.

More materials = better color accuracy, but slower printing and more filament changes
Tips
  • Meshy.ai Exports: Use the "Export with Texture" option to get OBJ+MTL+PNG in a ZIP
  • Material Count: Start with 5 materials for best balance of quality and print time
  • Texture Quality: Higher resolution textures give better color sampling
  • Slicer Compatible: Output works with Bambu Studio, OrcaSlicer, and PrusaSlicer
  • Filament Selection: After import, match the generated colors to your available filament colors in the slicer
