Flexible Polymers

3D Printing Elastomers - TPU for SLS 3D Printer

Materials of the TPE polymer class have similar properties to elastomers – this means that they are flexible at room temperature but still remain dimensionally stable. When heated, they can be plastically deformed and processed like thermoplastics. Since they are easy to process, they can be used to replace cross-linked elastomers and soft PVC. 

Fields of Application

TPEs can for example be used to make damping elements, bumpers, bellows, soles, handles and hoses.

Global Take-back Program for Used Polymer Materials & Parts

The VIRTUCYCLE® program globally takes back used polymer material and 3D printed parts, using 100 % renewable energy to transform powder into recycled high-performance injection molding granules & extrusion products. EOS carried out a Life Cycle Analysis, critically reviewed by TÜV Süd, which confirmed that 1 kg of polymer material converted into 0,945 kg granules saves approximately 7 kg of CO2e compared to the raw material, in order to verify the positive environmental impact.
