Abstract
This invention is based upon the discovery that prototype parts having physical characteristics that mimic those of powder metal parts can be made by laser powder bed fusion techniques in cases where water or gas atomized powder metals are employed in the laser fusion procedure. More specifically, parts made utilizing water or gas atomized powder metals in such additive procedures, using unique printing parameters to create desired porosity levels within the component, have densities and microstructures that approximate those made using conventional powder metal manufacturing techniques. For instance, such parts can be made so as to have a density which is within the range of about 6.0 g/cc to 7.8 g/cc and which have physical properties that are equivalent to those of powder metal parts of comparable densities.
