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.
Suggested filament printing parameters
| Printing temperature | From 220°C to 250°C |
|---|---|
| Table temperature | From 30°C to 60°C |

If you experience problems with filament extrusion, you should:
- Loosen the screw that regulates the pressure level of the knurl on the roller
- Reduce printing speed
- Install the Teflon tube sealing the filament feed path
Filaments are hygroscopic, meaning they absorb moisture. Therefore, breaking the airtight vacuum packaging permanently reduces the quality and value of the product. For this reason, if an unpacked item is returned, the refund amount will be proportionally reduced. This does not apply to returns resulting from manufacturing defects in the material, such as damaged or cut filament. Please carefully check the color and material type on the label before opening the foil packaging. |
