SLM 500


Quad-laser system with permanent filter


The first quad-laser metal system on the market, SLM®500 can integrate lasers independently or in parallel to increase build rates by 90% over twin laser configurations. SLM®500 is the best performing, most efficient system in its class, and 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.


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 

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.

SLM 500 Materials


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).

SLM 500 Case Study


Automotive Steering Knuckle from Hirschvogel Tech Solutions

 Machine: SLM®500 Quad
 Material: AlSi10Mg
 Layer Thickness: 60 µm
 Build Time: 2d 7h 23m (Maximized Build Chamber, 1 Unit)

Hirschvogel Tech Solutions based the automotive steering knuckle development on an integrated approach taking the entire additive manufacturing process chain into account. This part combines a high level of development expertise in light weighting, as well as in the application of designs based on bionics, achieving a 40% weight saving in the neck area compared to the conventional forged part. Production requires few support structures leading to reduced post-processing effort.
