We explore the laser powder bed fusion (LPBF) of pure nickel and use it as a case study to investigate the influence of laser beam diameter and shielding gas flow speed on the density, surface roughness and crystallographic texture of printed parts. As we increased the laser beam diameter from 45 Ám to 180 Ám, the density and surface roughness of the parts improved. The crystallographic texture of the samples printed with serpentine strategy transits from <111> to <100> along the scanning direction when printed with slow and fast shielding gas speeds respectively. Our work provides insights to suitable processing conditions for LPBF of metals. Furthermore, as nickel is a pure element, our study can be used as a baseline for researchers working on simulations related to microstructure of pure metals produced via LPBF.
