White CoexFlex™ 30D TPE
CoexFlex™ 30D TPE is our second most flexible filament. With great layer adhesion and soft nature, it make very durable and flexible prints 30D can be referenced on the Shore Hardness scale. CoexFlex™ 30D TPE is a TPC (Thermoplastic Copolyester Elastomer), which exception temperature resistance, abrasion resistance, and tensile strength.
CoexFlex™ TPE/TPU lineup of filaments will give you the best results when you require a flexible 3D Printing Filament. Proudly made in the USA.
Technical Printing Guide - COEXFLEX 30D
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. Basic Parameters
Unlike rigid filaments, TPE 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 | 0.35mm | 2.5 mm³/s | 240°C |
| 0.6mm | 0.3mm | 0.55mm | 5.6 mm³/s | 240°C |
| 0.8mm | 0.4mm | 0.75mm | 10.0 mm³/s | 240°C |
| 1.0mm | 0.5mm | 0.95mm | 15.6 mm³/s | 240°C |
3. Speed Settings
0.4mm Nozzle (Volumetric Speed: 2.5 mm³/s)
| Line Type | Percentage | Speed |
| External Perimeter | 50% | 17.86mm/s |
| Internal Perimeters | 75% | 26.79 mm/s |
| Infill | 100% | 35.71 mm/s |
| Top/Bottom | 60% | 21.43 mm/s |
| First Layer | 30% | 10.71 mm/s |
0.6mm Nozzle (Volumetric Speed: 5.6 mm³/s)
| Line Type | Percentage | Speed |
| External Perimeter | 50% | 17.00 mm/s |
| Internal Perimeters | 75% | 25.50 mm/s |
| Infill | 100% | 34.00 mm/s |
| Top/Bottom | 60% | 20.40 mm/s |
| First Layer | 30% | 10.20 mm/s |
0.8mm Nozzle (Volumetric Speed: 10.0 mm³/s)
| Line Type | Percentage | Speed |
| External Perimeter | 50% | 16.67 mm/s |
| Internal Perimeters | 75% | 25.00 mm/s |
| Infill | 100% | 33.33 mm/s |

| First Layer | 30% | 10.00 mm/s |
1.0mm Nozzle (Volumetric Speed: 15.6 mm³/s)
| Line Type | Percentage | Speed |
| External Perimeter | 50% | 16.42 mm/s |
| Internal Perimeters | 75% | 24.63 mm/s |
| Infill | 100% | 32.84 mm/s |
| Top/Bottom | 60% | 19.70 mm/s |
| First Layer | 30% | 9.85 mm/s |
4. 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 | 1.8-2.8mm | 35mm/s | 0.2mm |
| 0.6mm | 1.8-2.8mm | 35mm/s | 0.2mm |
| 0.8mm | 2.0-3.0mm | 35mm/s | 0.2mm |
| 1.0mm | 2.0-3.0mm | 35mm/s | 0.2mm |
5. Temperature Settings
Bed Temperature: 25-85°C
Extruder Temperature: 205-225°C
6. Cooling Settings
Cooling Configuration:
- General: 0% (fan off)
- Force fan speed for overhangs and bridges: OFF
- Layers < 20 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.
