| Abstract Scope |
Direct energy deposition (DED) is a type of additive manufacturing process utilizing powder, wire or a combination of the two as feedstock. DED is notable for its high deposition rate and is capable of producing large-scale complex functional parts and thin walls. Typically, a set of optimized processing parameters is provided on a material or 3D printer basis. It is crucial to understand the effects of different process parameters on the bead geometry and solidification behavior to be able to minimize the defects and improve the mechanical properties of the additively manufactured products. In this study, 316L stainless steel samples are manufactured using a laser-wire DED system equipped with a six-beam laser head with coaxial wire feed. The influence of processing parameters on the bead geometry and solidification microstructure is analyzed and discussed. |
