Product description: Rosa3D Flex 85A Filament 1.75mm 0.5kg - included with a reusable spool - Black
Flex 85A filament is a thermoplastic polyurethane (TPU) designed for FFF/FDM 3D printers . The material is pre-wound on a reusable spool and vacuum-sealed. The filament diameter is 1.75 mm . Designed for technical applications, its flexibility and excellent interlayer adhesion make it suitable for applications requiring mechanical resistance and tensile strength. The filament is resistant to grease, oils, and many solvents.
Our range of filaments also includes other materials and colors.

Practical use of Flex 85A filament
- Smartphone cases
- Parts for drones and RC cars
- Seals and covers
- Device housings
- The filament does not require a heated bed or chamber
- In case of adhesion problems, we recommend using an adhesive agent.
- It is recommended to cool the print
- It is recommended to start slowly and gradually increase the printing speed.
