| Abstract Scope |
Additive Manufacturing (AM) has the potential for improving the sustainability of metal processing through decreased energy and materials usage compared to casting and forging. Laser powder bed fusion (L-PBF) of high-temperature alloys such as nickel alloy 718 is one of the key modalities supporting this effort. One of the major drawbacks to L-PBF is its slow build speed on the order of 5-10 cubic centimeters per hour print speed. Our team is investigating speeding up L-PBF printing 10x by switching from a traditional Gaussian laser shape to a ring laser shape using a nLight multi-modal laser. The objective is to increase productivity dramatically while only marginally increasing energy consumption by switching to the ring laser thereby improving the sustainability of L-PBF. Results include measuring the energy consumption of an Open Additive L-PBF system during the Inconel 718 printing and comparing the microstructure and mechanical properties of the two different lasers. |
