SLM®280 Production Series

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. The SLM®280 Production Series utilizes our patented multi-laser scan strategy to minimize soot interference, alter layer stitching and deliver results with the same density and mechanical properties as single-laser builds.

Gas Flow Ensures 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

Permanent Filter Module Improves Uptime and Reduces Costs

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, while 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

Gooseneck Kueger Flap Actuation Bracket - Asco Industries

Machine: SLM®280 Twin
Material: Ti6Al4V
Layer Thickness: 30µm 
Build Time: 1d 19h 11m (Maximized Build Chamber, 2 Units)

This structural component from a Krueger flap actuation mechanism was optimized at ASCO Industries in the course of the AFLoNext Project. Through additive manufacturing, 31% weight savings and a reduction of the total assembly time could be reached. It integrates three parts into one reduced assembly and has an improved buy-to-fly ratio reduced from 17 down to 1.5. The build time was significantly reduced by 42% using a SLM®280 Twin, compared to single-laser machines.

Cross-Jet Unit - Fronius

Machine: SLM®280
Material: AlSi10Mg
Layer Thickness: 60µm
Build Time: 20h (Maximized Build Chamber, 10 Units)

The heart of the welding process is the hybrid welding head with both an integrated GMA welding torch and laser optics. Fronius uses a cross-jet unit to protect the laser optics from contamination during the welding process. Using SLM® technology the company combined 18 individual components into one and increased flow performance while reducing weight and costs.

Monolithic Thrust Chamber - Cell Core GmbH

Machine: SLM®280
Material: IN718,
Layer Thickness: 30µm
Build Time: 3d 5h 25m (Maximized Build Chamber, 1 Unit)

This monolithic thrust chamber of CellCore GmbH directly integrates multiple parts and internal features. It has an improved functional cooling due to an innovative lattice structure, which also increases stability. It is highly efficient and minimizes individual process steps while combining multiple individual parts into one component; production time reduced from months to days.

​​​​​​A byproduct of the welding process is submicronic soot and condensate, which can be pyrophoric by nature. 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, while clean gas returns to the process chamber.

  • Long-life filter ensures part quality throughout builds without interruption
  • No changing of filter cartridges
  • Reduced consumable costs
  • Safer operation by avoiding loaded filter housing exchange
  • Dry mixture waste disposal without hydrogen formation with reactive materials

Tool for visualizing thermal emission of melt pool in the SLM®process. The system records the thermal radiation produced from the melt during the entire production process.

  • Sequential output of thermal emission plot images of individual layers
  • Detect irregularities and defects in parts
  • Log and document build jobs in MPM-Files

 

Permanent on-axis laser power monitoring system that measures and illustrates nominal and actual power during the ongoing manufacturing process.

  • Active warnings, highlighting spots with critical laser power deviation
  • Documentation of the laser power for each scan vector over the entire build job

Developed to simplify cleaning, maintenance and installation work on the SLM®Recoater.

  • Stable mount for maintenance
  • Safe handling
  • Station features 360° rotation for full maintenance access
  • Drip tray included for easy residual powder collection
  • Safe storage of recoating mechanisms
  • Station Dimensions: 730mm x 310mm x 250mm

Tool to level recoater height and adjust overlap area. Enables reproducible adjustments to the recoating lip height, independent from operator, within 1 μm. Resulting in recoating and the laser exposure level consistency for each build job.

Substrate plates with parts up to 180kg can be easily removed from the process chamber with the Build Plate Handling Device. 

  • Two-speed electronic lifting and lowering
