Medical, soft materials and PP

2020/10/20 — The Arburg Plastic Freeforming (APF) process with the freeformer is predestined for medical technology, the processing of soft materials and PP, and for the additive manufacturing of multi-component parts. High-temperature plastics can also be processed using the open system from Arburg. Arburg is presenting all of these topics at the Formnext Connect.

The freeformer in sizes 200-3X and 300-3X process plastic granulates of the kind also used in injection moulding. This also makes it possible to process bio-compatible, absorbable and sterilisable as well as FDA-approved original materials to be used.

»In medical technology, we can also accomplish very demanding applications with the AKF process that other processes simply cannot handle«, explains Lukas Pawelczyk, Head of Freeformer Sales at Arburg. As well as Resomer Composite LR 706 S ß-TCP, a product similar to human bone that tends to be used as a bone substitute, the freeformer was recently used to process another innovative absorbable material from Evonik: using a polymer from the Resomer-C family employed in the soft tissue sector, individual breast implants have been produced to showcase what can be achieved.

With the additive AKF process, it is possible to produce components from soft materials in virtually all Shore hardnesses. In relation to mechanical load-bearing capacity, recoil characteristics, UV stability and endurance strength, these components share almost the same properties as injection moulded parts, as Arburg reports. With the slicing parameters, various material densities can be achieved within a part. As well as medical technology applications and the processing of soft materials, at the Formnext Connect, Arburg will be presenting an impressive example of additive manufacturing from the multi-component sector, a functional part made of PP and TPE to demonstrate a classic hard/soft combination. The manufacture of parts from a high-temperature plastic rounds off the range.
