How to create flat multicolor 3D prints
Flat multicolor prints are front-viewed plates with distinct color layers. FlatStack quantizes artwork into printable bands on a thin solid mesh.
Artwork tips
Solid fills beat soft gradients when you want fewer filament swaps. Separate logo colors in your design tool before export.
- PNG with transparent background for logos
