TPU 95A

Category: TPU

Material Information

Name: TPU 95A
Source: "Elasto 95A" from Plural Additive Manufacturing
Description:

TPU95A (thermoplastic polyurethane) is a semi-flexible, chemical resistant filament, making it the go-to-choice for a wide array of manufacturing projects that demand the qualities of both rubber and plastic. It is highly versatile for industrial applications due to its high impact strength and resistance to wear and tear. In addition, it is also easier and faster to print than other TPU filaments.

    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: Beginner Intermediate Advanced Expert

    • 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.
