Energy Efficiency influence of Gaussian and Ring-shaped beam profiles for LPBF

Ersilia Cozzolino,
Austin Tiley,
Antonio J. Ramirez
et al.

Abstract: Additive Manufacturing (AM) has the potential for improving sustainability of metal processing through decreased energy and materials usage compared to casting and forging. Laser powder bed fusion (LPBF) of high temperature alloys such as nickel alloy 718 is one of the key modalities supporting this effort. One of the major drawbacks to LPBF is its slow build speed on the order of 5–10 cubic centimeters per hour print speed. This experimental study investigates how to increase the productivity of LPBF process … Show more
