While 3D printing technology does allow complex metal parts to be produced efficiently, such items often deform when stressed and heated. That may soon no longer be the case, however, thanks to a new ...

While our desktop machines are largely limited to various types of plastic, 3D printing in other materials offers unique benefits. For example, printing with concrete makes it possible to quickly ...

As a US Marine Corps combat engineer serving in Iraq, Jim Monroe used MacGyver-like hacks to repair mine rollers. Meant to detonate and clear mines, these heavy studded wheels are mounted on the ...

Many of today's metal-printing systems use lasers to heat and melt powdered metal feedstocks. Rosotics founder and CEO Christian LaRosa says there are a number of problems inherent in laser systems.

Microscope image showing the layered structure of a new 3D-printed aluminum alloy. The wave-like patterns are “melt pools,” traces left by the laser as it melted metal powder layer by layer. The small ...
