Abstract

This study reports the methods used by BWX Technologies' additive manufacturing (AM) division to obtain electron beam additive manufacturing (EBAM) parameter sets that enable the printing of crack-free, fully dense, pure molybdenum AM parts. Special focus is also given to explaining the unique capabilities of the machine used during the study; an Arcam Spectra H.
