What is TPE/TPU and why choose it?

TPE (Thermoplastic Elastomer) and TPU (Thermoplastic Polyurethane) are flexible filaments for 3D printing. Although often used interchangeably, there is a subtle distinction:

  • TPE is a generic term for thermoplastic elastomers, encompassing a wide range of flexible materials.
  • TPU is a specific type of TPE, based on polyurethane, generally offering better resistance to abrasion and chemicals.

These filaments are popular for several key reasons:

  1. Flexibility: Ideal for flexible, tough parts.
  2. Durability: Excellent resistance to wear and tear.
  3. Shock absorption: Perfect for applications requiring cushioning.
  4. Chemical resistance: Good resistance to oils and solvents, particularly for TPU.
  5. Adhesion: Strong adhesion between coats for solid parts.

Key technical data

  • Available diameters: 1.75mm and 2.85mm
  • Printing temperature: 220-250°C
  • Tray temperature: 30-60°C

Choosing the right TPE/TPU filament

Frequently asked questions

  1. Which TPE/TPU hardness should I choose? We offer a range of Shore A hardnesses, from very soft (88A) to more rigid (98A). The choice depends on the flexibility required for your project.
  2. What packaging do you offer? Our range of TPE/TPU filaments is available in several packaging options: Sample, 500g, 750g, 1kg, 5kg, 10kg.
    For specific packaging requirements, please do not hesitate to contact us.
  3. Is TPE/TPU suitable for functional parts? Yes, TPE/TPU is ideal for functional parts requiring flexibility, impact resistance or anti-slip properties.
  4. How should TPE/TPU be stored? Store your coils in a dry place, ideally in an airtight bag with silica gel. TPE/TPU is hygroscopic and can absorb moisture.

Common TPE/TPU applications

  • Shoe soles and sports protection
  • Seals and sealing parts
  • Non-slip handles and covers
  • Flexible automotive parts
  • Smartphone protectors

Printing tips for optimum results

  1. Temperature setting: Start at 230°C and adjust according to results.
  2. Tray adhesion: use a tray heated to 40-50°C for best adhesion.
  3. Print speed :
    • Standard printers: 20-40 mm/s, slower than PLA due to the flexible nature of the material.
    • Optimized printers: Up to 60-80 mm/s with specialized direct extruders.

    The optimum speed depends on several factors:

    • Hardness of TPE/TPU filament used
    • Extruder type (direct drive recommended)
    • Model complexity
    • Desired final print quality
  4. Shrink: Minimize shrinkage or disable it completely to avoid jamming.
  5. Extruder: A direct extruder is strongly recommended for TPE/TPU.
