GAO said Wednesday the department aims to design and build some weapon technologies through an additive manufacturing process in an effort to improve system performance.
The department is also exploring other potential uses of a 3D printer, the report states.
DoD officials interviewed by GAO for the report said they hold conferences or working groups to discuss the challenges they face when they implement additive manufacturing projects.
According to GAO, the department should appoint an official to oversee the development and implementation of a tracking system for department-wide 3D printing efforts.
