SLM 280 Production Series

Robust Selective Laser Melting

Equipped with a patented set-up comprising a sintered wall, the SLM 280 series creates a clean processing environment that increases build quality and reduces gas consumption.

Multiple Lasers and Process Stability for Demanding Applications

With a build plate 25% larger than standard mid-sized machines to fit more parts per build, the SLM®280 Production Series is a high-power, multi-laser machine designed for production-oriented additive manufacturing processes. The SLM®280 Production Series utilises SLM Solutions’ patented multi-laser scan strategy to minimise soot interference, alter layer stitching and deliver results with the same density and mechanical properties as single-laser machines.


Premium Quality and the Highest Productivity

Third-generation machine designed for production environments. Featuring multiple lasers, closed-loop powder handling and upgraded process controls are ideal for demanding applications to achieve high levels of productivity. The SLM®280 can be equipped with up to two 700W fiber lasers to accelerate the printing processes of variety of metal additive powders.

Patented bi-directional powder recoating helps reduce manufacturing time by depositing a new layer of powder in both directions, without having to return to a “home” position.

Gas Flow that Ensures the Highest Part Quality

The SLM®280 Production Series provides a patented, laminar gas flow that creates a clean process environment and increases quality throughout the whole build. Powder transport, sieving and storage is contained within an inert gas atmosphere to maintain powder quality.

The permanent filter module traps soot and condensate particles from the process gas stream in a sintered plate filter. The filter is purged with gas, the waste material coated with an inhibitor and dropped in a bin for dry disposal, as clean gas returns to the process chamber.

Closed Loop Powder Handling Increases Safety and Material Quality

Powder transport, sieving and storage is contained within a closed-loop, inert gas atmosphere to maintain material quality.

Efficient, Reliable, Repeatable

Equipped with a patented set-up comprising a sintered wall, the SLM 280 series creates a clean processing environment that increases build quality and reduces gas consumption.

A Support-Free Revolution

SLM Solutions launches the Free Float software solution. The addition of this latest technology to the brand’s offering allows for the creation of metal components with previously impossible designs, hence reducing the overall material usage and reducing end-part costs while achieving industrial-scale productions. This first-of-its-kind technology also allows for the printing of retrofittable 3D metal parts.

Benefits of Free Float

  • Reduce duration for post-processings
  • Overhang areas without structures
  • Reduces powder usage – more savings
  • Creates more build space – more room to build
  • Results in less scrap
  • Enables major reduction of internal part stress
