Tungsten Fabricated by Laser Powder Bed Fusion [PDF]

BHM Berg- und Hüttenmännische Monatshefte, 2021
AbstractAdditive Manufacturing (AM) is the process that allows the production of complex geometry and lightweight components. Thanks to the high density of refractory metals, AM could be a possible solution for their application in the aerospace field and for biomedical or future nuclear fusion devices. Yet, Laser Powder Bed Fusion (LPBF) of refractory
