TPU

TPU Of the many kinds of flexible 3D printer filaments, TPU is slightly more rigid, making it easier to extrude and use. TPU filament is used to 3D print a wide variety of items including custom phone cases, rubber mats, stress toys, and tires or shock absorbers for R/C vehicles. It is also great for applications such as vibration dampening and shock absorption. It prints on a much more wide range of 3D printers, and posses characteristics such as: Ease of print-ability  Extreme durability and impact strength while maintaining flexibility Ideal hardness to ensure compatibility on wide range of printers including bowden fed extruders Recommended print conditions: Extruder - 225-235C  Bed - 60-80C (Slow print speed down if you are having trouble with filament feeding)
