The research team at the Michigan Tech Open Sustainability Technology (MOST) Lab continues in their journey to explore 3D printing in metal with their open-source GMAW 3D printer and software. Now, they are examining the use of common aluminum alloys in 3D printing, outlined in their paper, ‘Structure Property Relationships of Common Aluminum Weld Alloys Utilized as Feedstock for GMAW-based 3D Metal Printing'. Here they look at the performance of numerous alloys overall, and then pinpoint which ones are superior in terms of bead width, porosity, strength, and defect sensitivity.
