Image to flat multicolor 3D print

Flat multicolor mode creates a printable object where all visible colors end at the same top height. It is useful for plates, signs, labels, badges and logos where color is the design and height should not change between regions.

When flat mode is the right choice

• The final part should feel smooth or almost smooth on top.
• Colors should be assigned to different filaments without raised relief.
• The object is a sign, label, car plate, name tag or decorative insert.
• You want the slicer to preserve color regions in the 3MF file.

Unified core and visible skin

Hidden internal color changes can create unnecessary filament swaps. Unified core replaces hidden interiors with one selected base color while preserving a visible color skin on exposed surfaces. This keeps the visible result intact and can reduce print time on multicolor machines.

Things to check in the slicer

Always inspect the sliced preview, not only the prepare view. Look for missing thin lines, unwanted filament changes inside hidden regions and borders affected by elephant-foot compensation. If very thin strokes disappear, enable thin-line detection in the slicer or print the object slightly larger.

Best images for flat multicolor prints

Simple artwork works best: logos, icons, clean text, high-contrast plates and designs with a small number of colors. Photographs can be converted, but the result usually needs more colors and more filament changes, so it is rarely the best use case.
