Abstract: Current progress in wire arc additive manufacturing (WAAM) is presented. Metal additive manufacturing has the potential to transform industries by providing optimally designed alloys, microstructure, and geometries. This research expands on past work using metal inert gas (MIG)-welding-based 3-D printing as a reliable, cost efficient, and practical AM process for aluminum manufactured parts. Initially the base MIG nozzle is used to greater understand the coupling of six different variables(Stand off distance, volumetric gas flow, power input, wire mass flow, travel speed, and nozzle geometry), influencing the WAAM process. Polymer 3D printing is utilized extensively as an aid in rapid prototyping components and improving the printing process. The use of electromagnetism is investigated in several forms to focus the plasma arc generated with the aim of improving resolution and material properties. Finally, as this is work in progress, future directions and goals will be discussed.

Bio: Adam is a PhD student in the Department of Materials Science and Engineering at Michigan Technological University. He currently a member of both the ARC (Alloy Research Central) and MOST (Michigan Tech Open Sustainability Technology) research groups under Dr. Paul Sanders and Dr. Joshua Pearce respectively. He graduated from Michigan Tech with a bachelors of science degree in materials science and engineering in 2016. His research interests include polymer, composite and metal additive manufacturing and open-source technology.
