Polymers manufacturer Covestro AG has introduced Arnite AM2001 GF (G), a recycled polyethylene terephthalate (rPET) for pellet-style 3D printers. The company says the material, made from used consumer products, supports its corporate goal of developing sustainable products.

The glass-fiber-filled material enhances the structural performance of parts while leaving a smaller carbon footprint than virgin material, according to Covestro. The material has been optimized for 3D pellet printing. The technology, also known as fused granulate fabrication, is designed to allow fast, economical printing of large parts.

Covestro recommends rPET for structural applications, including pedestrian bridges, tiles for cyclist or pedestrian tunnels, architectural applications like cladding or partition walls, indoor and outdoor furniture, small boats, and packaging crates.

rPET is the first 3D printing material from Royal DSM’s Resins & Functional Materials business, which Covestro acquired April 1.
