I see there has been a lot of discussion of which materials are good sellers. Coming to shapeways from a jewellery production background it is obvious that the various karatages of gold are materials which are missing from our choices. Given the proliferation of printing bureaus within the jewellery industry that are printing in gold it is obvious that 3D printing in gold is economically viable. For those unfamiliar with working in gold, it costs a lot more but that also means you can make more money per item sold. It would be nice to be able to get my gold printing and sales done here on shapeways. One other material I would like to see here is a pink high detail plastic.
