Directed energy deposition (DED) is one of additive manufacturing processes attracting attention from various industries. Foam metal is a material having beneficial characteristics, but is difficult to produce with conventional manufacturing system. This study proposes a simple foam metal fabrication method by applying DED. The proposed method produces foam stainless alloy in DED by adding a foaming agent, titanium hydride (TiH₂), into the powder material. This study evaluates the foaming behavior of porous stainless in DED by changing the particle size of TiH₂ and the number of layers per line, and obtains the optimal number of layers to improve the porosity dispersion.
