eSUN TPU-95A Translucent Aqua Flexible TPU Filament 1 kg
eSUN TPU-95A Translucent Aqua is a translucent aqua 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. TPU-95A is suitable for flexible technical parts, phone cases, watch bands, gaskets, shock-absorbing parts, protective pads, sporting accessories, insoles and elastomer prototypes.
The translucent aqua color combines a fresh blue-green shade with a light-transmitting effect. It is a good choice for flexible phone cases, protective pads, accessories, decorative inserts, bracelets, watch bands, sporting elements, marking parts and models where an elastic material with a clean translucent appearance is needed. With FDM/FFF printing, the material usually prints as translucent rather than fully transparent like glass. Final appearance depends on wall thickness, infill, temperature, speed, wall count and drying quality.
β Key advantages
- Shore 95A flexibility: elastic but still firm and controllable during printing.
- Translucent aqua effect: suitable for decorative parts, phone cases, accessories, light-transmitting elements and protective pads.
- 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 Translucent Aqua 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 clean translucent 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‘ Light-transmitting decorative and technical elements.
- β Watch bands, bracelets and wearable accessories.
- π± Phone cases and soft protective elements.
- π© Flexible mounts, dampers, gaskets and seals.
- π Insoles, soft inserts and shock-absorbing parts.
- π Sporting accessories and equipment parts.
- π·οΈ Marking inserts, color indicators and visual control elements.
- π§ͺ Elastic prototypes for testing shape, fit and translucency.
β 3D printer compatibility
eSUN TPU-95A Translucent Aqua 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 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
No. It is a translucent TPU. With FDM/FFF printing, it produces an aqua light-transmitting effect, but not glass-like clarity. Final appearance depends on wall thickness, temperature, speed, infill, wall count and drying quality. 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 translucent parts. It is well suited for translucent phone cases, protective pads, decorative inserts, bracelets, watch bands, sporting accessories, marking parts, light-transmitting elements and flexible technical parts. Use dry filament, stable temperature, moderate speed, thin walls and minimal infill. Before the main print, test different wall thicknesses on a small model.Is TPU-95A Translucent Aqua fully transparent?
