With an extended z-axis build envelope measuring 500 x 280 x 850 mm and available in a quad-laser configuration with four 400 W or 700 W lasers, the SLM®800 efficiently builds large components at up to 171cm3/h. This efficient build rate and large build envelope, combined with integrated powder handling and the design freedom afforded by selective laser melting, open new possibilities for large-scale production parts.

A clean process chamber is essential to successful builds with acceptable mechanical properties, especially in a process chamber where longer build times increase the amount of soot in the chamber. The optimized inert gas flow of the SLM®800 efficiently removes soot from the build chamber, ensuring excellent process conditions. With a continuous stream through a sintered chamber wall, the enhanced gas flow creates constant conditions at the work surface as well as protecting the beam entry glass from contamination to not hinder the lasers. The SLM®800 is also equipped with a Permanent Filter Module to further maintain a clean process chamber resulting in consistent atmosphere conditions that ensure optimal build quality. Comprehensive process monitoring modules, Laser Power Monitoring and Melt Pool Monitoring, are available to ensure process transparency and documentation. 

Offered with a manual unpacking station for single-machine setups, the SLM®800 combined with the SLM®HUB fully automated handling station maximizes machine uptime and offers a no-contact powder solution for production processes.



Customizable Unpacking Solutions


PRS 800


For single machine operation the PRS 800 is available for the manual unpacking of the build cylinder. After the completion of a build the build cylinder is removed from the machine and into an unpacking station across a linear axis. The powder is manually removed from the build with an integrated blasting tool and vacuum operated through a glovebox in the unpacking station. The inert atmosphere of the PRS 800 and powder management system ensures the quality of the powder is maintained for future builds and minimizes any potential powder contact by the operator.

The PRS 800 offers users a manual entry into large-scale part production. The basic unpacking station is upgradeable to the SLM®HUB to facilitate ease-of-use and minimize machine downtime when ramping up to production or integrating a multi-machine setup.




The SLM®800 reaches peak performance when paired with the SLM®HUB fully-automated handling station. This integrated solution features automated transport of build cylinders with dedicated locations for pre-heating and cooling in an inert atmosphere. The SLM®HUB also removes manual powder handling from the production process with a centralized powder supply and a powder removal chamber that rotates and vibrates the finished substrate plate to automatically separate all unused powder from the finished part and recycle it back to the sieving station for reuse in future builds. All machines connected to the SLM®HUB are fed metal powder through vacuum technology from the central powder station creating a completely closed-loop powder management system.



Up to five SLM®800 systems can be modularly connected to and operated from a single SLM®HUB. With a build cylinder magazine (BCM) multiple build cylinders can be handled in parallel to optimize machine uptime and scale to full production.
