Laser power 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 uses a
variety of process parameters that ultimately determine the overall quality and mechanical
properties of a print. The ability to alter parameters allows for the utilization of various metals in
this form of AM. Maraging 300 steel (M300) is a material of particular interest due to its combined
tensile strength and high strength-to-weight ratio. By using an assortment of parameters and
comparing the resulting mechanical properties it can be determined which process parameters
result in a more favorable part to be used in a variety of applications. A favorable process parameter
set was selected for future use. This study aims to determine which process parameters result in
the best overall mechanical properties of M300 manufactured using L-PBF.Mechanical Engineerin
