More information about antibacterial TPU filaments for 3D printers

  • Suitable for printing flexible 3D accessories such as mask holders, ear savers, door openers, and many more.
  • You can also use this material to make splints, prostheses, and other elements used to treat injuries.
  • Its composition helps prevent the formation of fungus, bacteria, and other microorganisms on the surface of printed pieces.
  • Semi-rigid structure for easy printing and a soft finish.
  • Natural-coloured filaments have a translucent appearance, with a slight amber colour.
  • Similar to PLA filaments in extrusion temperatures, but with a higher compressive and tensile strength.
  • Suitable for 3D printers with direct or Bowden extrusion systems.
  • 100% recyclable filament, non-toxic, with food-grade certification. This material is safe to use by children.
  • Delivered in a cardboard box, vacuum packed and wound on clear plastic spools.

  • TPU is a material prone to absorb moisture. When this happens, the filament can make bubbles or creaks when printing. 
  • To remove moisture, you can use any of the following strategies:
    • Leave the filament in a closed room with a dehumidifier for 24 hours.
    • Place the filament in an oven for 2 hours at a temperature of 60°C.


  • Filaments tend to absorb moisture from the environment, leading to problems during printing or finishing. For this reason, it is important to keep the relative humidity value between 10-15%.
  • Moisture may cause the filament to degrade, clogging the extruder and varying it’s physical and mechanical properties.
  • To keep the filament in good condition, it needs to be stored and dried correctly.
  • The filament must be stored in airtight containers, preferably vacuum packed. You can use zip bags with silica gel beads, vacuum-sealed bags or food containers with a vacuum seal.
  • There are many techniques to remove moisture, including:
    • Conventional methods such as drying the filament in a home oven or a food dehydrator. At low temperatures for long periods of time.
    • Professional ways such as using a filament dryer.
  • The useful life of a filament can vary according to different factors. That is why it is important to follow the manufacturer’s recommendations for drying and storage parameters.
