Image to keychain Make a 3D printed keychain from an image
Upload a logo, icon or transparent PNG, choose a final width and export a multicolor 3MF.
Transparent pixels become real cutouts, so you can prepare clean keychains, tags and badges
without cleaning unwanted background colors after quantization.
For keychains, start with 80 to 120 mm width, 0.2 mm/pixel resolution and 0.8 to 1.2 mm
thickness. Use flat multicolor mode when every visible color should print at the same height,
or relief mode when letters and details should rise above the base.

The alpha channel is treated as geometry, not as another color. Fully transparent pixels are
excluded from the model, while black, white and other opaque colors remain printable
filaments.
3MF vs STL Why export 3MF instead of STL?
STL only stores geometry. 3MF can carry multiple colored objects, making it a better format
for multicolor slicers such as OrcaSlicer and Bambu Studio.
Multicolor printing Flat color or raised color
Use flat multicolor mode for printed signs, logos and color plates. Use relief by color when
you want each detected color to have its own height.
