Abstract Scope Refractory materials are well suited to benefit from additive manufacturing due to existing limitations in processing these materials via conventional means. Nonetheless, obtaining high density and defect free material is a nontrivial task which requires high processing temperatures along with clean inert environments. Here we present our work on the processing of pure Tungsten using electron beam powder bed fusion to produce fully dense, crack-free material. In addition, we investigate the resulting process-sensitive microstructures and corresponding property relationships.
