Abstract
Laser powder bed fusion (L-PBF) is an additive manufacturing (AM) technology using a high-power laser to selectively melt metal powders for building complex parts. Coping with contamination in the powder is usually a challenge for this technology. Gases entrapped in the material in contact with the laser create a plasma of impurities that can lead to porosity. This contamination is usually coming from moisture, organics and adsorbed gases from the atmosphere (i.e. oxygen and nitrogen). In this work, two drying strategies to reduce the formation of porosity will be investigated.
