[Lecture Summary]

As gas-atomized powder is spherical and excellent in flowability, it has mostly been used in the L-PBF method. On the other hand, water-atomized powder has mainly been used in AM for the BJ (Binder Jetting) method. The authors tried to fabricate using MIM (metal injection molding) SUS316L water-atomized powder with an L-PBF method 3D printer. The powders used were two types produced by Epson Atmix Corporation with average particle sizes of 10 microns and 5 microns, and their sphericity is at the same level as gas-atomized powders. As a result, the relative density of the fabricated body was over 98%, which was at the same level as that of the body fabricated from gas-atomized powder. The evaluation method of this powder using Malvern Panalytical’s Morphologi 4 and rheometer will also be reported.
