82A FILAFLEX – White – 1.75MM 500gr. RECREUS
Description
Filaflex 82A “Original” is Filaflex’s flagship flexible filament and the most widely used TPU in 3D printing. With a Shore stiffness of 82A and an impressive elongation at break of 650%, this thermoplastic polyurethane filament provides exceptional flexibility, returning to its original shape without deformation after stretching. As the industry standard for flexible printing, it combines reliability with outstanding performance.
Designed for optimum print performance, Filaflex 82A is recommended for use with direct extrusion 3D printers and requires specific configuration guidelines other than for rigid filaments. The filament features excellent adhesion to the platform without the need for a heated platform or additional adhesives, and is odorless and resistant to a variety of solvents and fuels. Its non-toxic nature makes it safe for skin contact, opening up a host of practical applications.

🌡️ 1. Preparation of the material
Drying of filament (VERY IMPORTANT):
- 📏 Temperature: 55°C
- ⏱️ Minimum time: 1 hour
- 💡 Proper drying is essential for optimal printing results
⚡ 2. Understanding print speed
Volumetric versus linear velocity
- 🌊 Volumetric velocity (mm³/s): Like water through a hose – measures how much plastic flows per second, regardless of nozzle size.
- 📏 Linear speed (mm/s): As the walking speed – how fast the printer head moves in the print area
- 🔑 Key formula: Linear velocity = Volumetric velocity / (Line width × Layer height)
✨ Magic: When you set a volumetric speed limit in the slicer, it automatically calculates and adjusts all linear speeds (perimeters, fill, etc.) based on the current nozzle size and layer height. This ensures consistent material flow regardless of print settings!
⚙️ 3. Basic parameters
Unique features of Filaflex 82A
Unlike rigid filaments, TPU stretches when extruded, forming thinner lines. The width of the line will be smaller than the diameter of the nozzle. To ensure proper bonding between vertical walls and perimeters.
| Nozzle | Layer height | Line width | Volumetric speed | Temperature |
|---|---|---|---|---|
| 0.4mm | 0.2mm | 0.35mm | 3.2 mm³/s | 240°C |
| 0.6mm | 0.3mm | 0.55mm | 7.2 mm³/s | 242°C |
| 0.8mm | 0.4mm | 0.75mm | 12.8 mm³/s | 245°C |
| 1.0mm | 0.5mm | 0.95mm | 20.0 mm³/s | 248°C |

️ 5. Withdrawal settings
🚀 IMPORTANT: Set the running speed to the maximum value your machine allows (200-500 mm/s). Faster movements reduce the time for the filament to run out, minimizing the formation of threads.
| Nozzle | Distance | Speed | Z-Hop |
|---|---|---|---|
| 0.4mm | 1.5-3.0mm | 40mm/s | 0.2mm |
| 0.6mm | 1.5-3.0mm | 40mm/s | 0.2mm |
| 0.8mm | 2.5-3.5mm | 40mm/s | 0.2mm |
| 1.0mm | 2.5-3.5mm | 40mm/s | 0.2mm |
🌡️ 6. Bed temperature settings
Bed temperature:
- Small parts: no heating (room temperature)
- Large parts: 45-50 °C
❄️ 7. Cooling settings
Cooling configuration:
- Total: 0% (fan off)
- FAN ALWAYS: OFF
- Forced fan speed for overhanging parts and bridges: OFF
- Layers < 8 seconds: 50% fan
- First layer: always 0%
🔧 8. Troubleshooting guide
| Problems | Solution |
|---|---|
| Uneven extrusion: | 1. Dry the filament 2. Check the extruder 3. Reduce speed |
| Weak adhesion: | 1. Dry the thread 2. Use glue 3. Apply glue with glue stick (use glue stick) |
| Stringing: | 1. Dry the filament 2. Adjust the withdrawal 3. Increase the running speed 4. Check the temperature |
✨ 9. Best practices
- 🌡️ Keep filament dry – store it properly and dry it before use
- ⚙️ Preferably use a direct drive extruder
- 🔄 Print multiple small parts at the same time for better results
- 🚀 Use maximum running speed to minimize lint formation
⚠️ PLEASE NOTE: These print parameters are initial recommendations based on our experience. They may need to be adjusted depending on your specific 3D printer, environmental conditions, and the geometry of the printed part. Use these settings as a starting point and adjust them according to your specific needs.
