Meshy can turn a photo, a sketch, or a text prompt into a fully colored 3D model ready for multi-color 3D printing. This guide walks through the full pipeline — from choosing your input to slicing the final print.
Step 1: Choose Your Input
Photo — use Image to 3D for the most accurate colors and proportions from a real object.
Sketch — a clean line drawing or colored sketch works well with Image to 3D; simpler sketches produce more predictable results.
Text prompt — use Text to 3D when you don't have a reference image and want Meshy to design the model and colors for you.
Step 2: Generate the Model
Generate your model as usual, then refine the texture pass if colors look muted or inaccurate. Once you're happy with the result, move on to preparing it for multi-color printing.
Step 3: Set Up the Multi-Color Print
Click the printing icon at the bottom of the viewer and choose Multi-Color Printing.
Pick a color count between 1 and 16 — 4 colors is a good default for balancing quality and print complexity.
Adjust the Level of Detail to match how intricate your model's textures are.
Step 4: Export as 3MF
Always export the optimized multi-color model as 3MF — this is the only format that preserves the color regions Meshy generated. Exporting as STL will discard all color data.
Step 5: Slice and Print
Import the 3MF file into Bambu Studio, OrcaSlicer, or another AMS/MMU-capable slicer. The color assignments should carry over automatically. Fine-tune individual regions with the slicer's color painting tool if needed, then slice and print.
Troubleshooting
Colors missing after import: confirm you exported 3MF, not STL.
Colors look faded or off: increase the color count or Level of Detail before exporting.
Model geometry has holes: clean up the mesh in Blender or Meshmixer before running the multi-color export.
FAQ
1. Can I get multi-color prints from a text prompt alone?
Yes — Text to 3D generates both geometry and texture, which you can then run through the Multi-Color Printing tool the same way as an image-based model.
2. How many colors should I choose?
4 colors is a good starting point for most printers. Fewer colors print faster and simpler; more colors capture finer detail but add complexity for your slicer and printer.
3. Does this work with printers that don't have an AMS or multi-material unit?
Multi-color 3MF workflows are designed for AMS/MMU-style setups. On single-extruder printers without color-swapping hardware, you'll need to manually paint or swap filament between prints.
