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 pre-wound on a spool and vacuum-packed. The filament diameter 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 grease, oils and many solvents.
In our offer of filaments you will also find other materials and colors.
