New technology revolutionizes 3D metal printing, LED instead of laser or electron beam

sledm

Graz University of Technology has developed a technology that uses LED instead of laser sources for the additive manufacturing of metal parts and optimizes 3D metal printing in terms of construction time, metal powder consumption, equipment costs and post-processing effort. Selective LED-based melting (SLEDM) – i.e. the targeted melting of metal powder using high-power LED light sources – is the name of the new technology that a team led by Franz Haas, head of the Institute of Production Engineering at TU Graz, has developed for 3D metal printing and has now applied for a patent.

Metal 3D Printing: Stronger Components, Faster Development

A team from California’s $6 billion lab, The Lawrence Livermore National Laboratory (LLNL), has announced research on a major issue “plaguing a common metal 3D printing technique.” The new discovery will be published in the August volume of peer-reviewed journal Acta Materialia and could lead to a faster adoption of 3D printing than previously anticipated.

The future for high quality components seems to be in metal 3D printing

Most everyone in the 3D printing industry is well aware that the future for high quality components seems to be in metal 3D printing. With that in mind, researchers have been steadily refining the process, and now a team at Northwestern University has come up with a process that even allows the use of inexpensive rust powder, which is more lightweight, offers greater stability, and is safer and more affordable in comparison to other iron powders.

Wire-feed additive manufacturing might be the future of metal-based 3D printing

Of all of the areas that have seen a lot of attention in the additive manufacturing space, the use of metal in the additive manufacturing process has not seen nearly enough attention as it should be. While the ability to ‘3d print a metal object’ is more complex and costly than thermoplastic parts, the finished products are arguably much more usable and long-lasting.

Uberblox: The Lego of the 3D printer age?

As cool and wonderful as Lego is, those plastic bricks can be tricky to handle if you want to step up from mere constructive play into serious custom-built prototyping. UberBlox hopes to fill that gap. It’s a metal construction set and prototyping system with a single-connector locking mechanism and a variety of control boxes for accommodating whatever computer connection or automation needs a project might have.
