eSUN TPU-95A Clear Flexible TPU Filament 1 kg
eSUN TPU-95A Clear is a clear 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, clear protective elements, phone cases, watch bands, gaskets, shock-absorbing inserts, sporting accessories, insoles and elastomer prototypes.
Clear color is useful for parts where internal structure, light transmission, marking, fit or a decorative transparent effect needs to be visible. With FDM/FFF printing, clear TPU usually prints as transparent or translucent rather than glass-clear. Final transparency depends on wall thickness, temperature, speed, infill, wall count, drying quality and print settings.
β Key advantages
- Shore 95A flexibility: elastic but still firm and controllable during printing.
- Clear effect: suitable for translucent phone cases, protective pads, light-transmitting parts and technical models.
- 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.
- Good printability: TPU-95A is easier to control than softer TPU grades.
- FDM/FFF compatibility: works with most 1.75 mm filament 3D printers.

π§ TPU-95A Clear printing recommendations
- Dry the filament at 55 β 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 a cleaner transparent effect, use dry filament, stable temperature and moderate speed.
- For higher light transmission, test thin walls, low infill and fewer wall lines.
- If stringing appears, check drying, temperature, retraction and travel speed.
- After long print jobs, cleaning filament can be used to clean the nozzle.
𧩠Best applications
- π± Clear and translucent phone cases.
- π‘οΈ Protective pads, soft inserts and flexible housings.
- π‘ Light-transmitting decorative and technical elements.
- π© Flexible mounts, dampers, gaskets and seals.
- π Insoles, soft inserts and shock-absorbing parts.
- β Watch bands, bracelets and wearable accessories.
- π§ͺ Elastic prototypes for testing shape, fit and transparency.
- π Flexible parts for electronics, devices and technical mockups.
β 3D printer compatibility
eSUN TPU-95A Clear is compatible with most FDM/FFF 3D printers using 1.75 mm filament and supporting a 220–250 β 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. For clear and translucent parts, keeping the filament dry is especially important because wet TPU may cause bubbles, haze, stringing and unstable surface quality.
π¦ 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 β for more than 4 hours is recommended.
- For long print jobs, using a dry box or eBOX is recommended.
- If bubbles, popping, stringing, haze or unstable extrusion appear, dry the material before printing.

π‘οΈ 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.
β FAQ
With FDM/FFF printing, the material usually prints as transparent or translucent, but not glass-clear. Final transparency depends on wall thickness, temperature, speed, infill, wall count, drying and print settings. 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 β for more than 4 hours is recommended, especially if the filament has been opened or stored in a humid environment. Drying is especially important for clear parts. Yes. Clear TPU-95A is suitable for flexible phone cases, protective pads, watch bands, gaskets, soft inserts and other elastic parts. Use dry filament, stable temperature, moderate speed, thin walls and minimal infill. Testing different temperatures and wall thicknesses on a small model is recommended.Is TPU-95A Clear fully transparent?
