• 【True Rubber-Like Flexibility: 85a Shore Hardness & Skin-Safe Comfort】 This TPU 85A filament delivers a genuinely soft, rubber-like feel that stays comfortable even against the skin. With an ultra-high elongation at break exceeding 574.34% and outstanding elastic recovery, it sacrifices a small amount of surface abrasion resistance compared to TPU 95A, and in return gives you unmatched softness, shock absorption, and a conforming, body-friendly touch.
• 【Upgrade Engineered Formula】 Our professionally reinforced formula achieves True Rubber-Like Flexibility and practically indestructible layer bonding. No matter how hard you stretch, twist, or bend the model, the layers will not delaminate or crack. Designed for Minimal Stringing, this TPU requires very little post-processing—a quick pass with a heat gun is often all that's needed. The precision 1.75mm ±0.03mm diameter ensures steady, consistent extrusion even at low speeds.
• 【Built for Soft-Touch Applications】 At 85A shore hardness, this material stretches and flexes effortlessly, making it perfect for functional seals, vibration dampeners, and skin-contact wearable parts. Typical applications include soft drone bumpers, shock-absorbing feet, functional waterproof seals, watch bands, prosthetic liner cushions, custom insoles, and all kinds of body-friendly, flexible components.
• 【Critical Tips: Direct Drive Only, Dry Thoroughly & Store Sealed】 This 85A TPU is extremely soft and must be used with a direct drive extruder
• It absorbs moisture quickly, so thorough drying is mandatory before printing: use a forced-air dryer at 80°C for 8–12 hours, or 100°C for 3–5 hours. Keep low print speeds, set retraction length to 0.4–1.4mm at 20–50mm/s, and use a 0.6mm (recommended) or 0.8mm nozzle. Always return unused spools to a sealed bag or dry box immediately.
• 【Recommended Print Settings】 Pre-print drying: forced-air dryer at 80°C for 8–12h or 100°C for 3–5h. Nozzle size: 0.6mm (strongly recommended) or 0.8mm. Nozzle temperature: 200–250°C. Build plate: standard smooth PEI or textured PEI sheet. Bed temperature: 35–50°C. Cooling fan: 30–70%. Print speed: ≤100mm/s (start at 20–50mm/s). Retraction length: 0.4–1.4mm, retraction speed: 20–50mm/s. Following these settings and test for verification will deliver stable, high-quality, super-soft flexible prints every time.
