Workflow

Step 1

Prepare model

Step 2

Plan colors

Step 3

Check MMU/material setup

Step 4

Save 3MF

Step 5

Verify in PrusaSlicer

Start with printability

Confirm that the model can print well before adding color. Fix scale, orientation, thin walls, and support needs early.

Plan color assignments

Map colors to meaningful regions and avoid unnecessary swaps where possible. Keep manual or MMU workflows in mind.

Use 3MF for handoff

Use 3MF when color or material assignments should carry into PrusaSlicer for final verification.

Verify before printing

Check material mapping, printer profile, supports, preview, estimated time, and filament usage before starting the print.

FAQ

Common questions

Can PrusaSlicer be used for multi-color prints?

Yes. Verify the workflow against the printer and material setup before printing.

Is 3MF better than STL for PrusaSlicer color work?

3MF is better when the color or material context needs to be preserved.

Can I plan color outside PrusaSlicer?

Yes. Use PrintNext Design to plan color, then verify the 3MF in PrusaSlicer.

What is the safest final check?

Use slicer preview and confirm material mapping before sending the print.
