Filadock TPU-LW 85A Foaming TPU Filament 1.75mm
Lightweight Foaming TPU for Shoes, Midsole & Flexible Printing
Lighter. Softer. Built for Performance.
Discover next-generation flexible printing with Filadock TPU-LW 85A.
Unlike conventional TPU, TPU-LW (Lightweight Foaming TPU) expands during printing to create lighter, softer and more comfortable parts.
Designed for 3D printed shoes, midsoles, wearable products and lightweight functional applications, Filadock TPU-LW combines flexibility, rebound and weight reduction in one advanced material.
Engineered for creators who want comfort without unnecessary weight.
What Is TPU-LW?
Lightweight Foaming TPU Technology
TPU-LW is a foaming flexible material designed to expand during printing.
Unlike standard TPU, TPU-LW uses controlled foaming technology to create:
✔ Lower density
✔ Reduced weight
✔ Softer touch
✔ Higher comfort
✔ Improved cushioning
Foaming performance can be adjusted through:
- Printing temperature
- Printing speed
- Material flow settings
This allows makers to fine-tune softness and weight according to project requirements.
Why Choose Filadock TPU-LW 85A?
Lightweight Foaming Performance
Print lighter without sacrificing flexibility.
Compared with conventional TPU:

⚠ Important Notice Before Purchase
⚠ Filament Only Included
The listed price includes filament only.
Printed shoes, demonstration models and display prints shown in product images are for display purposes only and are not included with the purchase.
⚠ TPU Feeding Support Recommended
Because TPU-LW is extremely soft and flexible, printing success depends heavily on reducing feeding resistance.
Without proper feeding support, excessive resistance may cause:
- Filament stretching
- Feeding instability
- Extrusion inconsistency
- Clogging
- Print failure
We strongly recommend:
✔ TPU filament feeder
✔ TPU booster system
✔ Low-resistance feeding path
Dedicated TPU support models can be downloaded from:
✔ MakerWorld
✔ Printables
For easier setup:
✔ TPU booster systems are available separately in our store.
⚠ Important Printing Recommendations
Because TPU-LW combines ultra-soft TPU with foaming behavior, proper preparation is critical.
⚠ Dry Before Printing
Moisture Control Is Essential
TPU absorbs moisture quickly.
Wet filament may cause:
- Stringing
- Bubbling
- Surface defects
- Foaming inconsistency
- Poor extrusion
Recommended Drying
✔ 55–60°C
✔ 4–6 Hours
Dry thoroughly before printing.
⚠ Dry While Printing
Continuous Drying Recommended
Because TPU-LW reabsorbs moisture quickly:
✔ Print directly from a dryer
✔ Keep filament warm and dry during printing
This helps maintain:
✔ Stable foaming
✔ Cleaner surfaces
✔ Better consistency
✔ Reduced stringing
⚠ TPU Feeding Recommendation
Shorter Filament Path = Better Printing
Because TPU materials are highly flexible, the shorter and smoother the filament path, the higher the printing success rate.
Excessive resistance may cause:
- Filament stretching
- Feeding instability
- Nozzle clogging
- Print failure
Recommended Setup
✔ Short feeding path
✔ Low resistance
✔ Smooth guidance
✔ Direct drive preferred
⚠ Top-Mounted Filament Holder Recommended
For TPU-LW, minimizing resistance is critical.
We recommend placing the filament above the printer using a top-mounted filament holder.
This setup helps:
✔ Reduce drag
✔ Improve feeding stability
✔ Minimize TPU stretching
✔ Increase print reliability
⚠ Direct Drive Preferred
For best performance:
✔ Direct drive extruder recommended
✔ Better filament control
✔ Reduced buckling risk
Bowden systems may require advanced tuning.
⚠ Foaming & Printing Speed Recommendation
Speed and Temperature Affect Foaming
TPU-LW foaming performance is influenced by:
- Temperature
- Speed
- Flow settings
Recommended:
General Speed Range
100–300 mm/s
Users may fine-tune settings depending on:
✔ Desired softness
✔ Expansion level
✔ Printer setup
Higher temperatures and suitable tuning may increase foaming and reduce density.
