colorFabb nGen_FLEX Black 1.75mm filament is a semi-flexible 3D printing material. nGen_FLEX is a co-polyester developed by colorFabb and Eastman Chemical Company. 


colorFabb nGen_FLEX is a functional flexible filament, with good layer adhesion to create watertight parts which are temperature resistant to 125°C, making it well suited to functional models, parts and prototypes. As a co-polymer, nGen_FLEX is engineered to print at regular speeds and can be printed with multiple parameters; more infill generates firmer and tougher prints, whereas small objects or those printed with little infill will feel quite flexible.


colorFabb nGen_FLEX is rated a shore hardness of 95A, and can be steam sterilised at 121°C.


Each colorFabb nGen_FLEX spool contains approx. 650g of filament and is available in 1.75mm and 2.85mm diameters in Black or Dark Grey.
