Evolv3D™ OBC (Olefin Block Copolymer) is an engineering-grade polyethylene copolymer. OBC is the state-of-the-art in polyethylene 3D printing and eliminates many of the problems associated with printing polypropylene-based materials.
Evolv3D™ OBC Polyethylene Copolymer 3D Printing Filament
Evolv3D™ OBC Polyethylene (Olefin Block Copolymer) from Dow is an engineering-grade material based on a novel polyethylene copolymer. OBC is the state-of-the-art in polyethylene 3D printing. It eliminates many of the problems associated with printing polypropylene-based materials. OBC Polyethylene is semi-crystalline and has excellent chemical resistance coupled with ease of printing and real-world functional properties.
The reels contain 750g of filament, but based on the very low density of OBC Polyethylene, this is the same amount of filament that would typically be found on a 1kg reel of ABS. This allows you to print light-weight and exceptionally durable parts for medical, drones, watercraft, automotive, or any application which would benefit from a light weight, chemically resistant material.
