Filadock 85A TPU is designed for applications where softness and flexibility are essential.
85A TPU is especially suitable for:
Its softness and rebound properties make it ideal for modern footwear printing.
Suitable for:
85A TPU helps reduce vibration and absorb impact.
Ideal for:
Comfortable and durable for repeated use.
Useful for:
Real flexibility for real-world applications.
Not all TPU materials are the same.
Compared with conventional 95A TPU, 85A TPU is significantly softer and more flexible.
This makes it ideal for:
✔ Comfort-focused applications
✔ Soft wearable products
✔ Flexible footwear
✔ High-deformation parts
Because of its extreme flexibility, 85A TPU may require more careful printing setup than harder TPU grades, but the performance advantages are worth it.
The softer the material, the greater the creative freedom.
Because 85A TPU is highly flexible and moisture-sensitive, proper preparation and setup are essential for achieving the best printing performance.
TPU naturally absorbs moisture from the air.
Moist filament may cause:
Proper drying significantly improves print quality.
✔ Drying Temperature: 60°C
✔ Drying Time: 6 Hours
For best results, thoroughly dry the filament before printing.
Because 85A TPU absorbs moisture quickly, we strongly recommend:
✔ Printing directly from a filament dryer
✔ Keeping filament warm and dry during printing
Continuous drying helps provide:
✔ Stable extrusion
✔ Cleaner surface finish
✔ Reduced stringing
✔ Better printing consistency
Dry filament prints better.
Because TPU is highly flexible and elastic, the shorter and smoother the filament path, the easier and more reliable the printing process becomes.
Excessive feeding resistance may cause:
To improve printing reliability, we strongly recommend using a TPU-optimized feeding setup whenever possible.
✔ Short filament path
✔ Low feeding resistance
✔ Smooth filament guidance
✔ Direct drive preferred
For ultra-soft 85A TPU, minimizing feeding resistance is extremely important.
We recommend using a top-mounted filament holder positioned above the printer whenever possible.
This setup helps:
✔ Reduce feeding resistance
✔ Improve feeding stability
✔ Minimize filament drag
✔ Reduce TPU stretching
✔ Lower clogging risk
A shorter and more direct feeding angle generally produces better TPU printing results.
Because of its extreme softness:
✔ Direct drive extruder strongly recommended
✔ Better filament control
✔ Reduced buckling risk
✔ Improved extrusion consistency
Bowden systems may require advanced tuning depending on printer design.
85A TPU is softer than standard TPU and benefits from controlled extrusion.
20–40 mm/s
Up to 60 mm/s
Higher speeds may increase:
Slower printing generally delivers cleaner surfaces and more stable results.
Too much retraction may cause:
Recommended:
✔ Low retraction
✔ Conservative settings
✔ Fine tuning based on printer setup
Recommended:
✔ Clean build surface
✔ PEI or textured build plate
✔ Moderate first-layer pressure
Avoid excessive nozzle squish, which may affect material flow.
