Abstract Scope |
Directed Energy Deposition (DED) is a type of Additive Manufacturing that uses wire, powder, or a combination of both as the feedstock. DED offers advantages such as high deposition rate, lower cost, and capability of manufacturing large-scale functional parts, which makes it valuable to many industries. The goal of this study was to produce location specific microstructure using wire-laser DED processing in 316L stainless steel. To achieve this goal, it is essential to understand the effect of process parameters on the microstructure and texture formation. Meltio M450, a coaxial DED system equipped with six laser beams, was used in this study. The influence of process parameters including laser power, printing speed, wire feed rate, hatch spacing and scanning strategies were investigated. The samples were analyzed using optical and electron microscopy as well as electron backscattered diffraction. |
