Product description: Filament Rosa3D Flex 85A 1.75 mm 0.5 kg - Black
Filament Flex 85A is a thermoplastic polyurethane (TPU), designed for 3D printers working in FFF / FDM technology. The material was factory wound on a spool and vacuum packed. The diameter of the filament is 1.75 mm . The material intended for technical applications, thanks to its flexibility and excellent interlayer adhesion, is suitable for applications where mechanical resistance and tensile strength are required. The filament is resistant to greases, oils and many solvents.
In our range of filaments you will also find other materials and colours.
