This project focuses on a subset of additive manufacturing processes known as the laser powder bed fusion (LPBF) process. To expand the materials that can be used within these machines, experimental trials must be done, however, working with a commercial LPBF printer outside of its material capabilities, parameter windows, and retrofitting with monitoring equipment can void the warranty on a machine that could bear heavy on costs, on the order of hundreds of thousands of dollars. To address these limitations, we are tasked with designing and fabricating an economical LPBF prototype chamber for experimentation with various metal alloy powders and chamber gases while accommodating the addition of monitoring equipment.
