Today, there's no color embeded in .stl format. I've seen the .amf format was accepted, for future fusion360 release, but cloud printing company leader (Shapeways) doesn't support it :
Maximum file size:Filetypes:For color 3D prints:
Supported 3D files |
64 MB or 1 million polygons |
DAE, OBJ, STL, X3D, X3DB, X3DV, WRL |
DAE, WRL, X3D, X3DB, X3DV Textures files: GIF, JPG, PNG Upload as ZIP containing model file and textures |
Some .stl + basic xml color code would be nice (.wmrl).
