Destined to the automotive market, this bellows has been additively manufactured using a TPU 33 Shore D for the structure material and a PVOH (water-soluble material) to support cantilever part elements.

The removal of this support material is achieved by plunging the part into a tempered water tank. This process can be accelerated by regulating the water temperature and using a water pump.
Once the support material has been removed, the bellows is fully functional with the required flexibility.
