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).

Scientists from Purdue University and the University of South China have developed an AI-designed alloy specifically for 3D printing that is rust-proof, 30% stronger, and twice as ductile as ...

University of Arkansas graduate Zane Mebruer’s research shows metal 3D printing may work in a carbon dioxide atmosphere.

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 ...
