The Copper Polyamide tooling process from First-rate Mold Solution Co. Ltd involves the selective laser sintering of a copper and polyamide powder matrix to form a tool.

All of the sintering is between the polyamide powder particles.
The process boasts an increase in tool toughness and heat transfer over some of the other soft tooling methods. These characteristics are provided by the copper and can give the user the benefits of running a tool with pressure and temperature settings that are closer to production settings. The primary disadvantage is the low material strength.
