The High Speed Sintering process (HSS) represents a new type of industrial 3D printing. This powder-based additive manufacturing process does not require a laser or a scanner. This eliminates two production time-limiting factors, resulting in a consistent and fast manufacturing time.

Beim HSS-Prozess wird das Pulvermaterial mit einer absorbierenden Tinte bedruckt und anschließend mit einer IR-Lampe belichtet und aufgeschmolzen.

In particular, our very soft and elastic 3D printing material (TPU Soft) can be processed particularly well in the HSS process, as the thermal energy required for melting can be better absorbed. As a result, very fine and, above all, graded properties can be realized in terms of hardness.

This means that Shore A hardnesses between 50 and 75 can be achieved within a single installation space and within a single component. This opens up completely new possibilities in the field of 3D printing of elastomer components. For example, lattice structures, seat and back cushions, shoe soles or seals and dampers with completely new properties can be realized.

Elastomer component made of Launhardt TPU Soft with defined Shore hardness grades; soft on the left and hard on the right; manufactured in the HSS process at Fraunhofer IPA.

Under load, this TPU component demonstrates the possibilities that can be realized with defined and graded material properties.
