SLM Solutions SLM 800

The SLM Solutions SLM 800 is a large-format selective laser melting system engineered for high-throughput production of complex metal components. With a build envelope of 500 × 280 × 850 mm, it stands among the largest powder bed fusion platforms available for industrial serial manufacturing, enabling the production of tall structural components and large batches of smaller parts in a single build.

The SLM 800 features a quad-laser configuration with four 700 W fiber lasers operating simultaneously across overlapping scan fields. This multi-laser architecture dramatically reduces build times compared to single-laser systems, while the patented bidirectional recoating mechanism maintains consistent powder layer quality at high throughput. An integrated sieve station and closed-loop powder management system minimize operator exposure and support safe processing of reactive materials such as titanium and aluminum alloys.

The machine incorporates SLM Solutions' proven open-parameter architecture, giving engineers full control over laser power, scan speed, hatch spacing, and layer thickness. This flexibility supports material qualification for aerospace, medical, and defense applications where process traceability is mandatory. The build chamber maintains a tightly controlled inert gas atmosphere with oxygen levels below 0.1%, ensuring metallurgical integrity across the entire build volume.

SLM 800 installations are found in aerospace OEM facilities producing structural brackets, engine components, and fuel system hardware, as well as in contract manufacturing environments requiring high part throughput. The system's scalable architecture and validated process parameters for titanium, nickel superalloys, aluminum, and stainless steel make it a production-ready solution for demanding industrial applications.
