Inject an electric, high-visibility energy into your functional prototypes and custom designs. The SainSmart Rep-Flex Neon Scarlet TPU Filament delivers a striking, vivid cyberpunk red aesthetic paired with high-grade engineering flexibility. Whether you are printing impact-resistant phone cases, custom RC car tires, protective bumpers, or wearable gear, this vibrant, ultraviolet-reactive-style scarlet filament guarantees your projects command attention while taking severe physical abuse.
Engineered to bend, stretch, and absorb brutal impacts without cracking. Featuring a precise 95A Shore Hardness, this Rep-Flex polyurethane filament provides the ultimate sweet spot between rubber-like flexibility and desktop printing reliability. It exhibits outstanding elastic memory, structural dampening properties, and incredible tear resistance, allowing printed parts to compress and flex repeatedly under heavy loads while snapping right back to their original dimensions.
Say goodbye to under-extrusion and surface defects. SainSmart manufactures this flexible media to an ultra-strict diameter tolerance of 1.75mm (+/- 0.05mm), securing incredibly consistent plastic volume delivery through your tool head. Because TPU is naturally hydroscopic (moisture-absorbing), every single 800g spool is thoroughly dried at the factory and instantly vacuum sealed with a heavy-duty desiccant pack to preserve chemical purity and ensure bubble-free, pop-free printing straight out of the box.
Optimized Flow Control & Printing Success Guidelines
Extruder Hardware Recommendations: For the smoothest surface finishes and jam-free operation, a direct-drive extrusion system is highly recommended. Standard Bowden tube arrangements can achieve beautiful results when fine-tuned at slow, controlled feed rates.
Thermal Profiles: Out-of-the-box print performance is highly stable with a recommended nozzle operating temperature between 195°C and 230°C, and a low-temperature heated build plate set around 40°C to 60°C.
High-Friction Flow Mastery: To prevent mechanical buckling or filament binding, optimize your slicer software for a deliberate printing speed profile of 15 to 30 mm/s. Ensure your extruder nozzle is cleanly purged of harder plastics before loading.
