Is there any way to vary the material on one model say White S&F, Blue S&F etc? That way I could do it, or would I
have to upload each seperate piece as a seperate item?
There is no way of using more than one material or colour with another, on the same machine. You will have to split the model up and upload each piece separately. The Full Color Sandstone is actually printed and 'dyed' at the same time. Like an inkjet printer.
Don't forget if you split it up, to remember the minimum wall thickness for each material.jacantdesign@gmail.com
