Selective laser sintering (SLS) produces components with the best material properties from all the 3D-printing technologies for polymers.

To increase the range of available materials in the Project „Lasergestützter Aufbau von kundenindividueller Fußbekleidung (LAuF)“ the partners develop new types of thermoplastic polyurethane (TPU).

The materials are tested at the Fraunhofer IWM regarding their mechanical and tribological properties. Together with the partners parametric studies are conducted and modes of failure are identified under tribological and fatigue loading.

The results aim at making orthopedic products by 3D-printing.
