eSUN TPU-95A Black Flexible TPU Filament 1 kg
eSUN TPU-95A Black is a black 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, phone cases, watch bands, gaskets, shock-absorbing parts, protective pads, sporting accessories, insoles and elastomer prototypes.
Black color is a practical choice for functional parts, protective elements, phone cases, automotive pads, sporting accessories and technical prototypes where a clean, universal and wear-friendly appearance is needed.
✅ 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.
- Black color: practical for phone cases, mounts, gaskets, automotive parts and technical components.
- Good printability: TPU-95A is easier to control than softer TPU grades.
- 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
- 📱 Phone cases, protective pads and flexible housings.
- ⌚ Watch bands, bracelets and wearable accessories.
- 🔩 Flexible mounts, dampers, gaskets and seals.
- 👟 Insoles, soft inserts and shock-absorbing parts.
- 🚗 Automotive pads, damping elements and protective parts.
- 🏃 Sporting accessories and equipment parts.
- 🧪 Elastic prototypes for fit and shape testing.
- 🔌 Flexible parts for electronics, devices and technical mockups.
✅ 3D printer compatibility
eSUN TPU-95A Black 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.
- If bubbles, popping, stringing or unstable extrusion appear, dry the material before printing.

🛡️ 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
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. 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. Yes. Drying at 55 ℃ for more than 4 hours is recommended, especially if the filament has been opened or stored in a humid environment. Yes. Black TPU-95A is suitable for phone cases, watch bands, flexible mounts, gaskets, protective pads, insoles and other elastic parts. 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. Black color is practical for protective parts, phone cases, gaskets, pads and components used in daily life, workshops, vehicles or sporting equipment.Is TPU-95A Black flexible?
