Abstract

Direct energy deposition (DED) is one of additive manufacturing processes, which achieves high production efficiency by supplying material powder and irradiating high-power laser beam to a baseplate at the same time. Furthermore, the DED has a potential to produce a functional material by blending various material powders. Although a metal foam structure is well-known because of its beneficial functionality such as light-weight, the complicated foaming process requires a special equipment and long processing time. This paper proposes a simple fabrication method for metal foam structure by applying a blowing agent into DED. Metal foam structure can be produced by foaming the meltpool with titanium hydride which releases hydrogen in a high temperature environment. The proposed method certainly produces a foam structure in stainless steel by blending titanium hydride powder into stainless powder for DED.
