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 ...

With all the nasty things going on around us, there’s one aspect of human activity than makes us hopeful we are eventually going to overcome our difficulties: space exploration. Thanks to the ...

Welding is typically used to join two parts together, whether those parts be metal or plastic. There are various styles of welding, but we won’t go into those here. Casting is the act of pouring a ...

Engineers at MIT have taken a metal that usually trades strength for lightness and pushed it into an entirely new class, ...

When you see the term cold fusion, you probably think about energy generation, but the Cold Metal Fusion Alliance is an industry group all about 3D printing metal using Selective Laser Sintering (SLS) ...
