It seems backwards, but engineers from Northwestern University have made 3D printing metal easier (and eventually cheaper) by adding extra production steps to the procedure. (Paper available in PDF).
A close-up of a laser-directed energy deposition (LDED) system fabricating the novel AI-designed ultra-high strength steel, which achieves a rare balance of strength and ductility, excellent corrosion ...
Researchers have developed a new inexpensive method to 3D print metallic objects such as batteries, fuel cells and parts for rockets and airplanes, using rust and metal powders. While current methods ...
