This article and video got me thinking of how 3D printing can, will and has changed the jewelry business. The flexibility that the computer aided design software gives is just incredible. Some hard to make intricate designs can now be easier to make. I took a look at the Solidscape T76 3D wax printer that is used in casting parts. The printed wax is used to make a cast. Turns out this is an elaborate five stage process, including the pouring of the molten metal into the cast, cooling and then polishing. The other way of printing jewelry is to use a printer that prints in metal. This process uses glue and a powder form of the metal. The glue and metal are printed in layers and then it is heated, then polished. This video that shows how GE is using 3D Metal printing to print newly designed parts for the aerospace industry. Imagine what you could design when prices come down on these printers.
