Selective laser sintering

Selective laser sintering (SLS) is an additive manufacturing technique used to produce components layer by layer. The process, which is often referred to as 3D printing, has been used commercially for 25 years and has been investigated at Fraunhofer UMSICHT for 10 years. Originally used for rapid prototyping, it is now a production process for customized products and functional components. The challenges for selective laser sintering lie in the growing demand for customized materials as well as adapted and new system technology.

Solutions and services of Fraunhofer UMSICHT

We offer comprehensive expertise in the field of selective laser sintering: We produce laser sintering powder and carry out sintering tests on the SLS test rig developed by us. We adapt sintering plants to meet customer requirements or build new ones. Polymer manufacturers who develop SLS powders, plant engineers and laser manufacturers who want to build up SLS expertise benefit from our range of products. We are happy to advise users who require components made from special materials.

Unique selling points

With the SLS test rig, we have developed a test rig that allows sintering tests without restrictions on parameters with minimum powder quantities (from 500g) under realistic sintering conditions (60W CO2 laser, up to 250 °C installation space temperature) and minimal set-up times. These sintering tests make it possible to produce the first test specimens during material development.

How you can work with us

There are several ways to collaborate with Fraunhofer UMSICHT. We would be pleased to produce a customized version of the SLS test rig for you, which will be adapted to your special component, process, and material requirements. Alternatively, we perform sintering tests with your materials on our system at the institute.
