Chris Borge] has made (and revised) many of his own tools using a combination of 3D printing and common hardware, and recently decided to try metal casting. Having created his own tapping arm, he ...

Have you ever played with Rose’s metal? It’s a fusible alloy of bismuth, lead, and tin with a low melting point of around 100 °C. Historically, it’s been used as a solder for cast iron railings and ...

By applying machine learning techniques, engineers at MIT have created a new method for 3D printing metal alloys that produce parts far stronger than those made using traditional manufacturing ...

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 ...

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 ...

Humans have cast metal parts in basically the same way for thousands of years: by pouring molten metal into a mold, often made of compacted sand and clay. There’s a reason this ancient method is used ...

Aluminum is one of the most useful metals in modern life. It is light, strong, affordable, and easy to recycle. That is why ...

Metal 3D printing has long promised aerospace-grade parts at desktop scale, but titanium has stubbornly resisted that vision. A new approach called cold metal fusion is changing that equation, turning ...

Rocket engineering is shifting from painstaking machining and welding to a world where engines and tanks emerge from printers ...

More than 24 customer applications 3D printed in metal and ceramics, including aluminum, titanium, copper, platinum, and silicon carbide, to be on display The all-new PureSinter Furnace – a high ...

Engineers in automotive and aerospace are under pressure to cut costs without slowing projects orrisking safety. Prototypes ...
