General Comments

Characteristics

  • Exceptional wear, tear and heat resistance
  • High impact strength
  • Easy formability, elastic and flexible
  • Good corrosion resistance to many common industrial oils and chemicals (see Chemical Resistance Table in Print Guide)
  • Engineered for a fast and seamless 3D printing experience, compared to other TPUs

Applications

  • Industrial Manufacturing
  • Functional Prototypes
  • Aerospace, engineering, healthcare
  • Seals, tubes, gaskets, grippers, end effectors
  • Shoes and insoles
  • Bushings, gaskets
  • End-use parts
  • Custom phone cases, rubber mats, and stress toys.
  • Sports - applications that need strength, flexibility and plenty of impact strength.
  • Healthcare - 3D-printed organs for pre-surgery prep and custom-designed prosthetics enhance patient care.
  • Can be used for tires or shock absorbers and is even occasionally utilized to make O-rings and seals. In the world of DIY, TPU is fantastic for flexible parts or casings as well as parts that need to have resistance to sudden impacts and movement.
  • In short, if you need to make a custom rubber piece quickly and relatively easily, TPU is your go-to material.

Considerations

  • One downside to TPU is the printing speeds, which are rarely higher than 30 mm/s. This is because it’s difficult to push the proper amount of filament through the hot end, resulting in prints taking a lot longer to complete.
  • TPU doesn’t produce any notable levels of fumes while printing, but it’s not considered to be food safe. And though it’s a non-soluble material, it is hygroscopic, meaning that it will slowly absorb moisture from its surroundings, degrading over time.

Printing Skill & Experience - Intermediate 

  • When printing, TPU exhibits minimal warping and shrinkage and, like PLA, doesn’t require a heated bed, although it is recommended. The ideal print temperature is between 210 and 230 °C, but this may vary from one manufacturer to another.
