Covestro introduces 3D printing material made from recycled PET

covestro recycled pet for 3d printing
Covestro introduces its first product for 3D printing, developed by the additive manufacturing business recently acquired from DSM: a glass-filled, recycled polyethylene terephthalate. It can be used to make, for example, furniture such as this chair, a design by Michiel van der Kley.

Covestro has introduced a glass-fibre filled recycled polyethylene terephthalate (rPET) for 3D pellet printing. Made from post-consumer PET waste, Arnite AM2001 GF rPET fits Covestro's vision for a circular economy and illustrates how complementary the two organizations are in their approach to adding more value to additive manufacturing and industrial production overall.

The glass fibre-filled pellet material brings structural performance with a substantially lower carbon footprint than virgin material. Manufacturers can now make their supply chain more circular without the need to compromise on performance.

Increasing sustainability, reducing cost

The recycled PET has been optimized for 3D pellet printing. This technology, also known as fused granulate fabrication (FGF), allows for fast and economically viable additive manufacturing of large-size parts. 

Direct printing of applications lowers cost by reducing product development time. 3D printing also allows for design flexibility, which can help reduce material cost. 3D printing is an intrinsically more sustainable production method as it only uses the material that is needed. By making the material more sustainable, Covestro helps manufacturers shift toward a circular economy.  

Arnite AM2001 rPET's mechanical properties and broad processing window makes it ideally suited for structural applications across a variety of industries, including pedestrian bridges, tiles for cyclist or pedestrian tunnels, architectural applications like cladding or partition walls, indoor and outdoor furniture, small boats, packaging crates or tooling.
