Fenner Drives first entered the FFF/FDM 3D printer filament market with NinjaFlex, their highly elastic, flexible filament. Now the company has released a slightly stiffer version of NinjaFlex called SemiFlex. The company is well known for producing power transmission components like drives, belts and bushings, and as a result they've gathered lots of experience in materials development. NinjaFlex and SemiFlex are patent-pending thermoplastic elastomer (TPE) filaments. With their rubber-like properties, they allow for the 3D printing of flexible parts.
