Abstract In this work, high density Waspaloy ® specimens were produced using selective laser melting (SLM). SLM of Waspaloy ® powder was performed using a high power pulsed Nd:YAG laser. The laser parameters pulse energy (J), pulse width (ms), repetition rate (Hz) and scan speed (mm/min) were varied. Process parameter optimization was achieved using factorial analysis to investigate the relationship between specific processing parameters and the formation of Waspaloy ® specimens. The optimized processing parameters produced Waspaloy ® specimens that were 99.7% dense. The resultant laser melted specimen's height, width and contact angles were measured. Specimens were also tested for the occurrence of porosity and observed for microstructure.
