TPU is a specifically formulated flexible filament for easy & high speed printing on both direct and Bowden style 3D printers. TPU features an exceptionally high heat resistance (138℃) and can be stretched as far as 450% before reaching its breaking point. TPU does not require the use of a heated bed and can even be printed straight onto (clean) glass. TPU is the flexible filament for (semi)professional users who do not want to compromise and require a high mechanical flexible filament that prints easily. TPU is an extremely usable flex-filament with a wide variety of different applications such as Orthopedic insoles, Prosthetics, Vibration dampers and much more.Features: • Strong & Flexible • Works on Direct & Bowden style 3D printers • Printable at speeds of >75mm/s • Exceptionally high softening point of 138°C • 450% elongation at break • Resistance to oils, greases & microorganisms • Easily print watertight objects
