【95A High-Elasticity & Wear-Resistant TPU Material】: Crafted from premium thermoplastic polyurethane (TPU) with a Shore hardness of 95A±2, this filament balances exceptional elasticity and toughness. Prints easily withstand daily wear, impacts, and slight stretching/deformation—ideal for flexible applications like phone cases, insoles, watch bands, robotics parts, flexible toys, and more. Perfect for both creative designs and functional flexible components, blending softness with durability.
【Clog-Free & Bubble-Free for Smooth Printing】: Equipped with a patented clog-free formula and 24-hour pre-drying process, it minimizes jams and bubbles from the source, ensuring consistent, smooth extrusion. Each spool comes vacuum-sealed in a resealable foil bag with desiccants. For optimal performance, store in sealed containers with desiccants after opening (recommend drying at 65-70°C for 8+ hours if exposed to humidity). Even beginners can achieve stable, hassle-free prints.
【Strong Layer Adhesion & Smooth Surface Finish】: Enhanced layer bonding technology ensures tight interlayer adhesion with zero delamination risk, delivering prints with a flawlessly smooth surface. Boasting wear resistance, oil resistance, and anti-aging properties, it resists cracking or fading over time—whether for detailed decorative pieces or load-bearing flexible parts, maintaining high-quality appearance and structural stability.
【1.75mm High Precision & Wide FDM Compatibility】: Strict dimensional control guarantees a 1.75mm diameter with ±0.03mm tolerance, validated by an advanced CCD diameter inspection system for consistency. Fully compatible with most 1.75mm FDM 3D printers (desktop and industrial models), and optimized for direct-drive extruders—no frequent adjustments needed to work with mainstream devices.
【Helpful Printing Guides & Worry-Free Support】: Recommended settings: Nozzle temperature 180-210°C (356°F - 410°F), bed temperature 50°C - 70°C (122℉~ 158℉), print speed 20-40mm/s (adjust by printer model). Pro tip: Maintain storage humidity <20% RH (sealed with desiccants) for best results. Backed by lifetime after-sales support—from parameter to troubleshooting, we’re here to guide beginners and pros alike for a seamless 3D printing experience.
