Prepare the model first

Check geometry, scale, orientation, and printability before adding color. Clean setup makes later color painting more predictable.

Choose a color strategy

Use part-based color when the model is split cleanly. Use face or region painting for details and decorative surfaces.

Verify slicer settings

Before printing, confirm filament mapping, printer profile, supports, layer height, and estimated filament usage.

Use PrintNext for planning

PrintNext can help plan the colors and create a 3MF handoff before final Orca Slicer review.

FAQ

Common questions

Can Orca Slicer handle multi-color workflows?

Yes, but you should verify color and material assignments inside the slicer before printing.

Should I use STL or 3MF?

Use STL for simple geometry. Use 3MF when color or project context should be preserved.

Can PrintNext help before Orca Slicer?

Yes. PrintNext Design helps plan color and hand off a 3MF for verification.

What should I check before printing?

Check color mapping, printer profile, supports, scale, and filament estimates.
