The US Department of Defense is partnering with industry and academia on a multiphase CTMA initiative to enable the transition of AM throughout the DOD and its industrial base, taking a holistic approach regarding the research of feedstock, advanced materials and processes, automation and controls, post-processing, and non-destructive testing (NDT) evaluation for the qualification, inspection, and assurance of parts being produced via AM. The key AM areas to be addressed are:
- Wire Arc Additive Manufacturing (WAAM)
- Friction-Stir Additive Manufacturing (FSAM)
- Solid State Additive Manufacturing (SSAM) also known as Cold Spray Additive Manufacturing (CSAM)
- Advanced AM Materials Technology
Phase III will focus on CSAM, WAAM and FSAM. New CSAM applications will be developed, to include establishment and evaluation of new higher-temperature feedstock powders. WAAM applications will include fabrication of tooling for castings and manufacture of chrome-plating alternative materials. The effort to develop tooling for castings will focus on demonstrating the use of WAAM to create tooling with internal voids to use less raw material and lower the cost of tooling, multi-material WAAM to create tooling with location-dependent hardness, and post-WAAM machining to reach final dimensions. The effort to use WAAM for chrome-plating alternatives will focus on alternative ways to manufacture tubes which have been traditionally chrome plated on the inner diameter.
