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).

Rust powder is lighter, more stable, cheaper, and safer to handle than pure iron powders. Researchers have developed a new inexpensive method to 3D print metallic objects such as batteries, fuel cells ...

A machine-learning strategy has generated a new class of ultra-high strength and ductility steel for 3D printing that costs ...

A team of researchers has used machine learning to design a new stainless steel alloy built specifically for 3D printing, one ...

Researchers from the University of South China and Purdue University have successfully employed artificial ...

Washington: 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 ...
