The development of cheaper, more powerful lasers has always been a cause for excitement among hackers, and fiber lasers are no exception. One of the newer tools they’ve enabled is the laser welder, ...

Metal 3D printing can produce the most intricate rocket parts, using combustion-resistant material. While 3D printing isn't new, how has the technology advanced to face the more extreme conditions of ...

Methods Used in Aluminum 3D Printing Laser powder bed fusion (LPBF) is a method used to 3D print aluminum with a higher surface finish and high accuracy. This process is initiated by localized melting ...

The Mini Metal Maker is no longer just a prototype. In this interview, inventor David Hartkop shows off the production version and shares his plans to bring the 3D printer to market. By Daniel Sparks ...

The process – long dominated by industrial platforms – builds parts by spreading thin layers of metal powder and selectively ...

Researchers at Graz University of Technology have created a new type of 3D printer that uses LED instead of laser sources for additive manufacturing of metal parts. The new 3D printer can optimize 3D ...

While many designers and engineers find success with 3D-printing parts in plastic for prototyping and low-volume production, producing parts out of metal using similar technology has recently led to ...

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 ...

Our current level of technological development does not allow us to build things in space. In the best-case scenario, we are capable of assembling stuff in orbit, but the actual build of structures ...

The Apollo 13 moon mission didn't go as planned. After an explosion blew off part of the spacecraft, the astronauts spent a harrowing few days trying to get home. At one point, to keep the air ...

While firing a round with earlier plastic models of 3D-printed guns has proven difficult, this metal model has already shot 50 rounds successfully. Dara Kerr was a senior reporter for CNET covering ...

You normally think of HP as producing inkjet and laser printers. But they’ve been quietly building 3D printers aimed at commercial customers. Now they are moving out with metal printers called — ...
