White CoexFlex™ 60A TPU
**60A is very soft and can be challenging to print with. We recommend a direct drive extruder with a contained filament path (it will squeeze out any gap it can) and a PTFE-lined hot end (it tends to stick to the walls of an all-metal hot end). Seasoning an all-metal hot-end may help.**
CoexFlex™ 60A TPU is, by far, the most flexible filament on the market. At Shore 60A, it is much softer than Ninjaflex or Filaflex, feels like a rubber band, and produces finished parts that are completely flexible, no matter what infill density you use. Highly functional for applications that require stretch, flexibility, or compliance. (NOTE: Only printable with select printers capable of printing this durometer of filament. A direct drive extruder is required. If you are unsure if your printer can print this material, please contact us prior to purchase!)

Technical Printing Guide - COEXFLEX 60A
1. Material Notes
- Keep filament dry - store properly and dry before use
- If needed, dry at 55°C for 4 hours or more
- Preferably use direct drive extruder
- Print multiple parts sequentially to minimize stringing
- Use maximum travel speed to minimize stringing
2. Temperature Settings
Bed Temperature:
- Small parts: No heating (room temperature)
- Large parts: 40-45°C
Extruder Temperature: 205-225°C
- Due to thermal breakdown of the material, do not exceed 230°C
3. Basic Parameters
Unlike rigid filaments, TPU stretches when extruded, producing thinner lines. The line width will be smaller than the nozzle diameter. To ensure proper bonding between vertical walls and perimeters
| Nozzle | Layer Height | Line Width | Volumetric Speed | Temperature |
| 0.4mm | 0.2mm | 0.42mm | 2.0 mm³/s | 225°C |
| 0.6mm | 0.3mm | 0.63mm | 4.5 mm³/s | 225°C |
| 0.8mm | 0.4mm | 0.84mm | 8.0 mm³/s | 225°C |
| 1.0mm | 0.5mm | 1.05mm | 12.5 mm³/s | 225°C |
4. Speed Settings
0.4mm Nozzle (Volumetric Speed: 2.0 mm³/s)

| Infill | 100% | 30.30 mm/s |
| Top/Bottom | 60% | 18.18 mm/s |
| First Layer | 30% | 9.09 mm/s |
0.6mm Nozzle (Volumetric Speed: 4.5 mm³/s)
| Line Type | Percentage | Speed |
| External Perimeter | 50% | 14.15 mm/s |
| Internal Perimeters | 75% | 21.23 mm/s |

1.0mm Nozzle (Volumetric Speed: 12.5 mm³/s)
| Line Type | Percentage | Speed |
| External Perimeter | 50% | 13.44 mm/s |
| Internal Perimeters | 75% | 20.16 mm/s |
| Infill | 100% | 26.88 mm/s |
| Top/Bottom | 60% | 16.13 mm/s |
| First Layer | 30% | 8.06 mm/s |
5. Retraction Settings
IMPORTANT: Set travel speed to the maximum your machine allows (200-500mm/s). Faster movements reduce filament oozing time, minimizing stringing.
| Nozzle | Distance | Speed | Z-Hop |
| 0.4mm | 1.5-2.0mm | 30mm/s | 0.2mm |
| 0.6mm | 1.5-2.5mm | 30mm/s | 0.2mm |
| 0.8mm | 2.0-3.5mm | 30mm/s | 0.2mm |
| 1.0mm | 2.0-3.5mm | 30mm/s | 0.2mm |
6. Cooling Settings
Cooling Configuration:
- General: 0% (fan off)
- Force fan speed for overhangs and bridges: OFF
- Layers < 10 seconds: 40% fan
- First layer: 0%
7. Troubleshooting Guide
| Problem | Solution |
| Irregular extrusion |
1. Dry the filament 2. Check extruder 3. Reduce speed |
| Poor adhesion |
1. Dry the filament 2. Use adhesive 3. Adjust first layer |
| Stringing |
1. Dry the filament 2. Adjust retraction 3. Increase travel speed 4. Check temperature |
PLEASE NOTE: These printing parameters are initial recommendations based on our experience. They may need adjustment depending on your specific 3D printer, environmental conditions, and the geometry of the part you are printing. Use these settings as a starting point and fine-tune them according to your specific needs.
