3d printed copper embossing die

The grapevine motif was printed using ABS filament on acrylic sheet. As we discovered a while back, the ABS/acrylic combo has great stick properties and is almost impossible to release, which is perfect for this application.

After the print finished I laid a sheet of annealed copper over it and embossed it under a 40 ton hydraulic press using a urethane conforming die.
