⚠ Important Printing Recommendations
Because 85A Glow TPU combines ultra-soft TPU with abrasive glow minerals, proper preparation is essential.
⚠ Dry Before Printing
Moisture Control Is Critical
TPU absorbs moisture quickly.
Wet filament may cause:
- Stringing
- Bubbling
- Surface defects
- Poor extrusion
- Inconsistent printing
Recommended Drying
✔ 60°C
✔ 6 Hours
Dry thoroughly before printing.
⚠ Dry While Printing
Because TPU reabsorbs moisture quickly:
✔ Print directly from a dryer
✔ Keep filament dry during printing
Continuous drying improves:
✔ Surface quality
✔ Extrusion stability
✔ Reduced stringing
⚠ TPU Feeding Recommendation
Shorter Path = Better Results
85A TPU is extremely flexible.
The shorter and smoother the filament path, the higher the printing success rate.
Excessive resistance may cause:
- Filament stretching
- Feeding instability
- Clogging
- Extrusion inconsistency
Recommended Setup
✔ Short filament path
✔ Low resistance
✔ Smooth guidance
✔ Direct drive preferred
⚠ Top-Mounted Filament Holder Recommended
We recommend placing the filament above the printer using a top-mounted holder.
This helps:
✔ Reduce drag
✔ Minimize TPU stretching
✔ Improve feeding consistency
✔ Increase printing reliability
⚠ Direct Drive Strongly Recommended
For best results:
✔ Direct drive extruder
✔ Better control
✔ Reduced buckling risk
Bowden systems may require advanced tuning.
⚠ Hardened Steel Nozzle Recommended
Abrasive Material Notice
Glow additives contain mineral particles.
Like most glow materials, Glow TPU is more abrasive than standard TPU.
Recommended:
✔ Hardened steel nozzle
✔ Long-term wear resistance
✔ Stable print quality
Not recommended:
✘ Long-term use with brass nozzles
⚠ AMS / Automatic Feeder Notice
Because of:
- TPU softness
- Feeding resistance
- Abrasive glow minerals
Long-term AMS use is not recommended.
Direct feeding generally delivers the best results.
⚠ Printing Speed Recommendation
Slower = Better
Best quality:
20–40 mm/s
Maximum:
60 mm/s
Higher speed may increase:
- Feeding issues
- Stringing
- Surface inconsistency
