SLM®500

The best performing, most efficient system in its class, the SLM®500 is designed to ensure operator safety and lower overall operational costs. Machine operator and powder are separated through a closed-loop powder handling strategy that includes an automated powder sieve and supply. Designed for serial production, exchangeable build cylinder enables shortest possible fire to fire times reducing downtimes of the machine to a minimum. The patented multi-laser overlap strategy ensures consistent material quality. 

Selective Laser Melting for Serial Production

Increased productivity is crucial for production-oriented machines, and the SLM®500 is available with two or four lasers operating independently or in parallel. With 400W and 700W lasers available, users have the choice of laser power matched to their material, with the option of increased power to build in thicker layers for further productivity gains. The machine provides a laser overlap strategy for efficient processing. Testing proves comparable density and mechanical property results in overlap and single-laser scan areas.

Permanent Filter Improves Uptime and Reduces Costs

The permanent filter module traps process soot in a sintered plate filter that is purged with gas. The waste material is coated with an inhibitor and stored in a bin for dry disposal, while clean gas returns to the process chamber, stabilizing gas flow to ensure part quality throughout long builds without interruption. The elimination of consumable filter cartridges increases safety while improving machine uptime and reducing costs. Operators no longer need to flood filters and waste management is simplified as controlled diffusion renders a standard dry material for disposal.

Closed-Loop Powder Handling

Paired with the Powder Supply Vacuum (PSV), the SLM®500 protects the operator from exposed powder and keeps material under an inert gas atmosphere throughout the powder-handling process. Our 90l  tank makes pre-loading easy and paired with the sieves and transportation to the machine, is crucial for a safe closed loop powder process. Best in pair with the Part Removal Station (PRS). 

PRS for Efficient Unpacking

The Part Removal Station (PRS) reduces machine downtime by allowing one completed job to be unpacked while the next can begin on the machine. Build cylinders with completed jobs are transported out of the SLM®500 for cooling and powder removal in an inert atmosphere. Integrated gloves offer full access to remove material without exposing operators to metal powder. A vacuum hose, located directly in the PRS chamber, feeds unused powder directly back to the PSV for sieving and use in the next production build.

​​​​​​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

The PSV features a 90l tank for pre-loading and storage of metal powder. The automatic system sieves material before transportation to the machine for the build process, collects overflow powder to be returned to the sieve during the build, and also connects to the PRS unpacking station for powder removal after completion of a build.

The finished build cylinder is transported out of the system. Cooling and removal of excess powder takes place inside the part removal station (PRS), so that the next build process can begin immediately.
