Global industrial adoption of laser-based powder bed fusion (LPBF) technology is still limited by the production speed, the size of the build envelope, and therefore the maximum part size that can be produced. The cost of LPBF can be driven down furt

In Selective Laser Melting, the initial units produced are single tracks that overlap to create a single layer; from the sequence of layers, a 3D object is manufactured. The properties of the parts produced by SLM depend heavily on the properties of

High laser powers of up to 1500W were used to additively manufacture 17-4PH samples. Porosity was measured using quantitative image analysis technique, and all samples are fairly dense with a maximum of 0.42 percent porosity.
