eSUN TPU-95A White Flexible TPU Filament 1 kg with Plastic Roll

eSUN TPU-95A White is a white flexible TPU filament for FDM/FFF 3D printing with Shore 95A hardness. It combines elasticity, high resilience, tear resistance, wear resistance and good deformation resistance. The material is suitable for flexible technical parts, insoles, phone cases, watch bands, gaskets, shock-absorbing parts, protective pads, sporting accessories and elastomer prototypes.

The filament comes as 1 kg on a plastic roll. White color is useful for functional prototypes, test parts, parts intended for marking or painting, and models where surface quality needs to be visually checked.

✅ Key advantages

• Shore 95A flexibility: elastic but still firm and controllable during printing.
• High resilience: printed parts can bend and return to shape without quick deformation.
• Tear resistance: suitable for flexible parts exposed to stretching and bending.
• Wear resistance: a strong choice for pads, gaskets, straps and friction-exposed parts.
• Deformation resistance: printed parts keep their shape well in everyday use.
• White color: suitable for prototypes, medical mockups, sporting accessories, cases and paintable parts.
• Plastic roll: convenient for stable filament feeding and repeated storage.
• FDM/FFF compatibility: works with most 1.75 mm filament 3D printers.

🔧 TPU-95A printing recommendations

• Dry the filament at 55 ℃ for more than 4 hours before printing, especially if the spool has been opened.
• For best stability, use a Direct Drive extruder or a short filament path.
• On Bowden printers, print slowly: 20 mm/s or lower.
• Avoid sharp bends between the spool and extruder.
• Reduce retraction because TPU can stretch and compress inside the feeding path.
• Do not overtighten the extruder gear to avoid filament deformation.
• For flexible parts, use moderate speed, smooth acceleration and stable temperature.
• If stringing appears, check drying, temperature, retraction and travel speed.
• After long print jobs, cleaning filament can be used to clean the nozzle.

🧩 Best applications

• 👟 Insoles, soft inserts and shock-absorbing parts.
• 📱 Phone cases, protective pads and flexible housings.
• ⌚ Watch bands, bracelets and wearable accessories.
• 🔩 Flexible mounts, dampers, gaskets and seals.
• 🏃 Sporting accessories and equipment parts.
• 🧪 Elastic prototypes for fit and shape testing.
• 🚗 Automotive pads, damping elements and protective parts.
• 🔌 Flexible parts for electronics, devices and technical mockups.

✅ 3D printer compatibility

eSUN TPU-95A White is compatible with most FDM/FFF 3D printers using 1.75 mm filament and supporting a 220–250 ℃ nozzle temperature range. It can be printed on Creality Ender/K1, Bambu Lab A1/P1/X1, Prusa MK/XL/MINI, Anycubic Kobra, Elegoo Neptune, Sovol, QIDI, Flashforge and other popular 3D printers.

For TPU, a Direct Drive system is preferred. Bowden printing is possible, but it requires lower speed, careful retraction tuning and the straightest possible filament path.

📦 Storage and preparation

• Store TPU in a dry place, preferably in a sealed bag or container with desiccant.
• After opening, do not leave the spool exposed in a humid room for a long time.
• Before important prints, drying at 55 ℃ for more than 4 hours is recommended.
• For long print jobs, using a dry box or eBOX is recommended.
• The plastic roll is convenient for repeated storage and stable filament unwinding.

🛡️ Safety and certificates

TPU-95A is not classified as a hazardous chemical according to SDS/GHS, but normal ventilation, avoiding overheating and storing the material away from heat, sparks and open flames are still recommended during 3D printing.

According to official SGS reports, the material was tested for RoHS, REACH, EU Food Contact Safety, EN71 and FDA Total Extractives for submitted samples. This is not a universal guarantee for every finished part: food contact, skin contact, children’s products or special-use applications require consideration of part design, operating temperature, post-processing and application-specific requirements.

❓ FAQ

 

 

 

Is TPU-95A flexible?

Yes. TPU-95A is a flexible thermoplastic polyurethane with Shore 95A hardness. It is elastic, but still firm and easier to print than softer TPU grades.

Is Direct Drive required for TPU?

Direct Drive is preferred because TPU prints better through a short filament path. Bowden printing is possible, but 20 mm/s or lower speed is recommended.

Does TPU-95A need drying?

Yes. Drying at 55 ℃ for more than 4 hours is recommended, especially if the filament has been opened or stored in a humid environment.

Is TPU-95A suitable for phone cases and watch bands?

Yes. TPU-95A is suitable for phone cases, watch bands, flexible mounts, gaskets, protective pads, insoles and other elastic parts.

Can TPU be printed fast?

For stable printing, 20–50 mm/s is recommended. Well-tuned Direct Drive printers may print faster after testing, but slow speed is better for quality and consistency.

Is white TPU suitable for painting?

White TPU is useful for marking, prototyping and some painting applications, but paint compatibility with TPU should be tested on a sample part first.
