3-D printing is the usual name for the technique.

Ironically, Xerox itself just rented out space and sold part of 
its Wilsonville engineering group to 3DSystems at its Oregon 
location.  They do everything from plastics to metals to ceramics 
to edible stuff like chocolate.  If you need something printed in 
a non-standard material, they would be on my list of firms to 
talk with, especially as they have a service group that does on 
demand parts printing.  https://urldefense.proofpoint.com/v1/url?u=http://www.3dsystems.com/&k=diZKtJPqj4jWksRIF4bjkw%3D%3D%0A&r=YEYT9a57DeMCjLRn%2ByOKwM2slibCGhe2fkJNBp6S2cA%3D%0A&m=T8LRD8VtxIuf%2ByVZgh8GZJ108efW7WDwZn97B25A6iE%3D%0A&s=49fadf7f6cd5db0bbc4b6f61f826e0474f4c38493fabedabe9ed59163460c52d
