Covestro, a German manufacturer of high-performance polymers, has created a complex 3D printed shock absorber demonstrator using three different materials and additive manufacturing processes. This novel component will be showcased at the Fakuma 2018 trade fair next month in Friedrichshafen.

“This complex structure would not have been possible with conventional production processes,” said Lukas Breuers, Marketing Manager for 2D & 3D Printing at Covestro.

“The combination of different materials with various, tailor-made properties has enabled us to significantly expand the possibilities of additive production and its areas of application.”

Covestro - Range - Resins - Filaments - Powders

Covestro’s extensive range of resins, filaments, and powders, has served the automotive, construction, cosmetic, health and chemical industries since its inception in 2015. With the aim to bring “mass manufacturing to the 3D printing world with a range of high-quality products,” the company has developed a complex 3D printed shock absorber for the automotive industry.

Shock absorbers are critical hydraulic devices inside a vehicle’s mechanism which reduce unwanted kinetic energy. Using Selective Laser Sintering (SLS) and TPU powder, for its elasticity and high abrasion resistance, engineers fabricated the outer spring of the part which measures at 40 x 7 cm (15.7 x 2.8 in).

Adjusting - Shock - Absorber - Strength - Component

However, the adjusting **** inside the shock absorber required a high strength component for support. Thus, it is made from Covestro’s robust polycarbonate filament with FDM technology. Furthermore, the air chamber within the interior is created from a liquid PUR resin using the...
