3D Printed Sand Mold Design and Pouring

3D Printed Sand Molds for Complex Cores

OK Foundry designs and pours 3D printed sand molds for complex short run iron castings and serial production of castings requiring 3D printed cores. 3D printed molds and cores are an economical solution for short run castings having multiple cores, complex cores, or difficult cores.

3D CAD Design

OK Foundry has complete 3D CAD/CAM design capabilities including the latest version of Solidworks to design 3D printed sand molds and cores.

Castings from 3D Printed Sand Molds

OK Foundry has been designing and pouring 3D printed sand molds since 2012, just two years after ExOne introduced the S-Max sand printer in 2010. Since that time, we have continuously improved our ability to design and pour 3D printed sand molds and cores to solve unique casting problems.
