1 - Is this possible? Multiple materials on the same unique piece? For example... a cube, and each side of a cube have a different finishing? Or I need to upload multiple files (one for each material) and then "manually assemble" the final product? 2 - And can I print a photo/texture on any material? Or the object must be only with solid color? Any color os just the available material color? Thank you!
You'll find a lot of helpful info on our materials page https://www.shapeways.com/materials?li=nav 1) Each material has to be it's own file 2) See the materials page. We have full color sandstone and full color plastic which can use texture files or vertex coloring to have multiple colors on one piece.
