3D Printed Sand Molds for Economical Casting of Low Volumes

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 printed molds and cores can shorten the lead time for prototype or spare part castings, but tend to be most cost competitive for complex castings or small castings.

1912 Velie Engine Block

OK Foundry reverse engineered a 1912 Velie engine block and poured a new casting from 3D printed sand molds and cores. Laser scanning of the block was performed by Direct Dimensions, Inc. and the casting and printed molds were designed by OK Foundry. The Velie engine block had tight water jacket passages that required complex coring and to economically cast one engine block that was engineered over 100 years ago was a challenge only possible using 3D printed cores and molds and the foundry know-how of OK Foundry, also over 100 years in the making.
