Ideal for medium to high volume metal part production and prototypes, the next generation SLM®280 2.0 Selective Laser Melting System offers a 280 x 280 x 365 mm build envelope. With patented multi-beam technology pioneered by SLM Solutions, the SLM®280 can be equipped with up to two 700W fiber lasers. The integrated SLM® Build Processor and open software architecture offers the freedom of controlling system parameters to run standard builds or optimize to meet strict production needs and gain a competitive advantage.

The best-in-class gas circulation ensures efficient removal of soot from the build chamber for precision and optimal use of the full laser power. The high-efficiency filter system extends filter life with two main filters in parallel operation and a fine particle filter to further remove soot from the build atmosphere. The filter housing unit is also reusable and can be set-up with recyclable filter cartridges that help to reduce your overall operational costs. In addition, the patented bi-directional powder coating helps reduce the manufacturing time by depositing a new layer of powder in both directions without having to return to a “home” position. Coupled with the PSM powder sieve, material handling is performed in a safe and inert gas atmosphere.

As an open system, the SLM®280 allows the use of materials from any supplier. Operating parameters are easily tested and developed, simplifying the task of material development. A build volume reduction option allows users to process minimize powder usage, especially for research and development applications. Laser Power Monitoring and Melt Pool Monitoring quality assurance modules are available on single and multi-laser systems to monitor builds and aid in process transparency and documentation.

Achieve greater component quality for complex, delicate, yet fast part builds. SLM®280 systems regularly achieve 80% higher build rates than competitive single-laser offerings; accomplished by proper laser configuration and SLM Solutions’ bi-directional powder recoating.
