Key Features
✦ Ultimate Softness and High Elasticity (Shore 85A): Provides exceptional soft touch with elongation at break exceeding 600%, capable of withstanding repeated bending, compression, and stretching without deformation or fracture.
✦ Outstanding Impact Resistance and Shock Absorption: Excellent energy absorption characteristics effectively cushion external impacts, making it an ideal choice for protective components and shock-absorbing structures.
✦ Superior Wear and Tear Resistance: Demonstrates excellent wear resistance and anti-tearing performance, ensuring durability and extended lifespan for end-use components.
✦ Smooth and Stable Printing: The optimized material formulation features excellent flow characteristics, significantly reducing the risk of nozzle clogging, warping, or stringing during the printing process.
✦ Taiwan-Made Manufacturing with Quality Assurance: From raw material selection through production processes, everything is completed in Taiwan, ensuring every spool meets the highest quality standards.
Application
✦ Wearable Devices: Such as smartwatch bands, fitness trackers, VR device face cushions, and other wearables that require comfortable, skin-friendly contact surfaces.
✦ Medical and Assistive Devices: Ideal for custom orthotic insoles, prosthetic padding, medical model soft tissue simulation, and other healthcare applications.
✦ Shock Absorption and Cushioning Components: Including smartphone protective cases, drone landing gear pads, precision instrument bumpers, machinery vibration isolation pads, and similar protective elements.
✦ Flexible Seals and Gaskets: Capable of producing custom sealing rings, gaskets, and dust covers with excellent air-tightness and water-tightness properties.
✦ Realistic Models and Prototypes: During product design validation stages, can be used to create prototypes requiring soft touch simulation or elastic behavior modeling, such as button covers and grip wrapping layers.

Printing Recommendations
✦ Nozzle Temperature: 220 – 240 °C
✦ Heated Bed Temperature: 30 – 50 °C (applying a thin layer of glue stick can enhance adhesion)
✦ Print Speed: 20 – 40 mm/s (softer materials benefit from slower speeds to ensure stable extrusion)
✦ Retraction Settings: Recommended to disable or use lower retraction speed (< 25 mm/s) and shorter retraction distance (< 3 mm) to prevent material stretching or jamming in the extruder.
✦ Recommended Nozzle: ≥ 0.4 mm (for better flow characteristics, a 0.6 mm nozzle is recommended)
Important Notes
1. Material Drying: TPU materials have high moisture absorption. If the filament becomes damp, printing will produce crackling sounds, surface bubbling, or severe stringing. Before each use, pre-dry the filament at 55–60°C for 4–6 hours to achieve optimal print quality.
2. Extrusion System: While this material has been optimized for most extrusion systems, using a Direct Drive extruder typically yields more stable and reliable printing results compared to Bowden systems.
3. Storage Method: When not in use, store the filament in a dry sealed bag or desiccant box with drying agent. Recommended storage environment humidity should be below 20% RH.
