What materials are used in the production of the items on this site? Well, primarily, the below are my favourites, but there are many others to choose from and they can be seen here http://www.shapeways.com/materials/.
Gold-plated brass. Uses the lost-wax process, just as with sterling silver, but brass is used instead. This is then electroplated with nickel and, finally, a layer of 22kt gold.
– PA 2200
– Strong material
– Allows for good detail
Also comes in black, red, purple, pink and blue. You can colour this material yourself with standard fabric dyes.
– Smooth surface
– High heat resistance
– Less strength
– Extremely strong
– Quite detailed
– Quite smooth
Full-colour Sandstone. A full range of colours can be infused into the Sandstone material when printing. Surface has – predictably! – a fine sand-like texture.
Not for use with models that will be subjected to wear and tear due to relatively brittle nature of the material.
