The laborious machining required to remove metal support structures can take days - often longer than it took to 3D print the part itself. But thanks to the research of Arizona State University professor Owen J. Hildreth, Pennsylvania State University professor Timothy W. Simpson, and others, there's finally an easier way. Last year, we wrote about the development of a dissolvable support material, which the research team created for multi-material direct energy deposition (DED) 3D printing. Now, in a new paper entitled "Dissolvable Supports in Powder Bed Fusion-Printed Stainless Steel," the team details how they have continued their research to create - yes - dissolvable supports for powder bed fusion 3D printing.
