TPU98A is a specifically formulated flexible filament for easy & high speed printing on both direct and Bowden style 3D printers. TPU98A features an exceptionally high heat resistance (138℃) and can be stretched as far as 450% before reaching its breaking point. TPU98A does not require the use of a heated bed and can even be printed straight onto (clean) glass. TPU98A is the flexible filament for (semi)professional users who do not want to compromise and require a high mechanical flexible filament that prints easily. TPU98A is an extremely usable flex-filament with a wide variety of different applications such as Orthopedic insoles, Prosthetics, Vibration dampers and many more.

Additional information

TPU98A does not require a heated bed to stick well though you can set it to ≤60°C for extra reassurance.
TPU98A works superb with a direct drive feeder, or newer types of Bowden FDM or FFF technology 3D printers.
By changing the infill / amount of walls you can create the perception of a higher / lower shore than 98A.


Cool and dry (15-25˚C) and away from UV light. This enhances the shelf life significantly.

We will supply this product with a moisture content <0,2%. After being out of the bag for several hours, redrying in an oven is recommended to eliminate moisture. See page 4 for the recommended drying time and temperatures.
