| Abstract Scope |
Laser powder bed fusion (L-PBF) is a type of additive manufacturing (AM) that uses layers of powdered metal and a laser to manufacture a part in a layer-by-layer fashion. L-PBF has the ability to use a variety of process parameters for production of fully dense parts with satisfactory mechanical properties. Maraging 300 steel (M300) is a material of interest due to its combined tensile strength and high strength-to-weight ratio. This study aims to determine optimal process parameters of M300 manufactured using L-PBF by comparing the parameters effects on the resulting mechanical properties. Specifically, the primary process parameters (e.g., laser power and scan speed) were varied based on literature review and the as-built properties (e.g., tensile strength, and hardness) and conditions (e.g., surface roughness and porosity) were explored through statistical means for determining an acceptable parameter range. |
