FormFutura Python Flex TPU Flexible 3D Printing Filament Canada

Python Flex is a high-performance flexible thermoplastic polyurethane (TPU) filament, which is designed for high speed printing on both direct drive and Bowden style extruders.
Python Flex is an extremely easy to print flexible filament which can be printed directly on a glass plate without having to use the heatbed.
Python Flex has a shore hardness of 98A and has great elastic properties as allows itself to be stretched up to 450% before breaking.
Python Flex is extremely transparent in its natural form and has excellent resistance to oil, greases, microorganisms and abrasion.

Unique features:

  • Perfect combination of strength, flexibility and elasticity

  • Designed for high speed printing

    • Flexible filament that can be printed at speeds of >80mm/s

  • Heat resistant up to 138°C

  • Watertight printing possible with only single wall prints

  • Excellent resistance to oil, greases, microorganisms and abrasion

  • Very easy to print on both direct drive & Bowden style extruders

    • Warp-free printing and no deformation after cooling

    • Improved flowing behaviour and inter-layer adhesion

    • Good first layer adhesion to several (un)heated print surfaces

STORAGE: One large resealable bag with slider + an extra desiccant pack are included with every spool. The bag and extra desiccant are a great way to safely store your filament spool when not in use. It keeps your filament bone dry & free from any dust or dirt particles, so it's always ready for your next print.

3d printing temperature guideline Printing


220°C - 250°C
  • Nozzle size: ≥ 0.1mm
  • Layer height: ≥ 0.2mm
  • Flow rate: ± 110% - 130%
  • Print speed: Medium-Fast
  • Retraction: Yes, ± 5mm
  • Heat bed: ± 0 - 60° C
  • Fan speed: 50-100%
  • Print temperature depends on printing speed and wall thickness (e.g. ± 220 - 230° C for single wall objects with no infill at 50mm/s and ± 245 - 255° C for high infilled objects at 100mm/s)
  • Flow rate depends on configuration of hotend and feeder setup, but is increases when printing speed increases (e.g ± 110% for 50mm/s till even 130% for 100mm/s)


Python Flex is a very hygroscopic material and will attract and hold water molecules from the surrounding environment. When opened and exposed to humidity too long this can have a negative effect on the printing behaviour and quality of the filament. It is therefore strongly recommended to immediately remove the spool from the printer after printing and store it in a vacuum bag or airtight container without silica. When the filament is too wet it is recommended to dry Python Flex in an oven or filament drying machine at 65C. Drying time depends on how long the filament has been exposed to humidity. Python Flex is packaged in a vacuum bag with a guaranteed moisture content of less than 0,2% to ensure ideal printing behaviour and results directly after opening the spool.
