3D PRINTING IN FULL COLOUR
There are two ways to apply colour: as a ‘per face’ material or as a uv texture map. Per face materials are easier to work with but will give you less detail. uv texture maps can be very detailed but require the careful mapping of the texture map to your object. To use per face materials, simply apply material colours in your 3D application and export to VRML2. The use of texture maps requires some additional steps. shapeways only supports uv textures, no other texture projections. You can only use bitmap textures (no ‘procedural shaders’).
