silicone printing

Whilst researching 3D printing, i cam across a video from 2005 where a 2D file was printed in silicone.

while i don't have access to a 3D printer, i'm extremely interested in utiliting a similar technique in my materials studies.

i require a 'casing' that will house cut glass, and i'm thinking that silicone may be a possiblity...
