3D printing defects controlled with novel technique

A team of researchers from the US Department of Energy’s Argonne National Laboratory (IL, USA) has developed a technique for controlling 3D printing defects that can compromise the performance of 3D-printed parts. The technique, outlined in Additive Manufacturing, utilizes temperature data at the time of production as a predictive indicator for the formation of surface defects. The defects can then be addressed at the time of printing. “Ultimately you would be able to print something and collect temperature data at the source and you could see if there were some abnormalities, and then fix them or start over,” explained Aaron…
