Sand Core Tooling

This project seeks to develop the necessary tech data to additively manufacture select sand cores. The AM process is expected to drastically decrease the number of defects caused by the tooling process.


The Department of Defense is constantly seeking innovative solutions to improve the efficiency and effectiveness of its production processes. In line with this goal, the department has identified the need to replace the current sand core tooling process with a more advanced additive manufacturing (AM) process. This change aims to address the significant bottleneck caused by worn tooling and streamline the production of critical casting components. By adopting this cutting-edge technology, the Department of Defense is committed to enhancing its production capabilities and meeting the demands of modern warfare.


The objective for this project is to develop thetechnical data to replace select sand cores that are currently produced by atraditional tooling process with sand cores produced by an additivemanufacturing (AM) process. This will reduce defects and required weld repairs,eliminating a critical production bottleneck and creating surge capacity.
