WillowFlex Information

WillowFlex is a flexible 3D printing filament made from compostable raw materials. By combining material science, plastic production experience and new applications, WillowFlex is one of the most interesting 3D print filament options on the market. The filament is made from compostable raw materials (E.U. EN13432 and U.S. ASTM D6400), produced from non-GMO, US-grown corn stocks and has been tested by NSF International to be safe from phthalates, BPA, cadmium and lead. This makes it particularly interesting for fashion, toy and medical applications. The material was developed from the beginning as a bioplastic made to disrupt manufacturing by outperforming traditional plastics. The material also has unique technical properties because of its formulation. WillowFlex is a material that prints cleanly even on a cooled bed, has strong compatibility with other thermoplastics including PLA and is generally simple to work with. It also maintains its flexibility and stability above 100°C and below 0°C which allows a wider application range than most competing conventional flexible, plastic filaments. The final material is durable, strong and pliable. The most interesting WillowFlex applications have been in the fashion industry including clothing and footwear. But other smaller-industrial applications have included consumer goods, film props, toys and small-scale consumer goods.
