Designed to bridge the gap between traditional elastomer behavior and high-speed mechanical production, PolyFlex TPU90 offers exceptional elastic properties without forcing users to sacrifice structural print speed or reliability.\u003c\/p\u003e\n\n\u003cp\u003eFeaturing a uniquely high melt index, this material flows incredibly smoothly through the hotend, rendering it significantly easier to print than similar flexible filaments on the market. It exhibits outstanding tear resistance, remarkable layer-to-layer adhesion, and superior vibration dampening thresholds—making it highly effective for shock absorbers, seals, custom footwear prototypes, wearable electronics, and protective enclosures.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003eExtrusion Recommendation: To minimize material flexing or jamming during the feeding process, we highly recommend utilizing a direct-drive extruder setup (where the feeder mechanism is mounted directly atop the hotend assembly).\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003eKey Features \u0026amp; Advantages\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCovestro Addigy® Base Formulation:\u003c\/strong\u003e Built using elite industrial polyurethane technology to ensure consistent flexibility and durable part lifespans.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh Melt Index:\u003c\/strong\u003e Formulated for superior flow dynamics, allowing for faster printing speeds and a drastically reduced chance of nozzle clogs compared to standard TPU.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustrial Toughness:\u003c\/strong\u003e Exceptional impact absorption, excellent abrasion resistance, and strong chemical stability against oils and greases.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003e\u003cstrong\u003eTechnical \u0026amp; Printing Parameters\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Type:\u003c\/strong\u003e Thermoplastic Polyurethane (TPU)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Rating:\u003c\/strong\u003e 90A Shore Durometer (Offers a flexible, resilient elastic profile with great rebound)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilament Diameter:\u003c\/strong\u003e 1.75mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpool Weight:\u003c\/strong\u003e 0.75kg (1.65 lbs)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrinting Temperature:\u003c\/strong\u003e 210°C–230°C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBed Temperature:\u003c\/strong\u003e 25°C–60°C (No heated chamber required)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrinting Speed Range:\u003c\/strong\u003e 30mm\/s–60mm\/s\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCooling Fan:\u003c\/strong\u003e Enabled (ON)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDirect-Drive Retraction Setup:\u003c\/strong\u003e 3mm distance at 40mm\/s\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBowden (Indirect) Retraction Setup:\u003c\/strong\u003e 6mm distance at 60mm\/s\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Drying Instructions:\u003c\/strong\u003e Highly hygroscopic.
