Ahead of the International Manufacturing Technology Show (IMTS), the largest manufacturing trade show in North America, some 3D printing companies are already spreading their feathers. 

Stratasys announced two new 3D printing systems ahead of the event and, now, EOS has unveiled a new direct metal laser sintering (DMLS) machine, the EOS M 400-4.

The EOS M400-4 is an upgrade to EOS’ largest metal 3D printing system, the M400, named for its build volume of 400 x 400 x 400 mm. Whereas the M400 features only one 1Kw laser for sintering metal powders into solid metal objects, the M400-4 has four 400 W lasers, and is capable of fusing powder within 250 x 250 mm squares with an overlap of 50 mm. At launch, the machine can print with EOS NickelAlloy HX and EOS MaragingSteel MS1.

The printer is meant to bring a new level of speed and productivity to the series as EOS and other metal 3D printer producers reach for the mainstream manufacturing industry. In some ways, EOS is catching up with competitors like Concept Laser, Additive Industries and SLM Solutions, all of which make multilaser systems.
