Product description

Overview

Hello3D Flexible TPU 0.8 kg – Rainbow A is a high-quality flexible filament based on thermoplastic polyurethane (TPU) with an attractive rainbow appearance. Thanks to a Shore hardness of 95A, it is suitable for flexible functional parts as well as aesthetic models.

Note: The “Rainbow A” designation is used by Hello3D for rainbow colorway; the resulting color gradient may vary depending on the model length and the section of the spool.


Why choose this TPU

  • Flexible and durable material for cases, grips, damping elements, or hinges.
  • Stable diameter tolerance and clean winding for reliable feeding.
  • Practical packaging: vacuum-sealed with desiccant, ready to print.

Recommended print settings

  • Nozzle temperature: 190–225 °C
  • Bed temperature: 0–60 °C
  • Print speed: ~25 ± 10 mm/s (with TPU, slower is better)
  • Nozzle: ≥ 0.4 mm
  • Extruder: ideally direct drive; for Bowden, print slower with minimal retraction.
    These parameters are based on Hello3D’s recommendations for TPU (0.8 kg) and common TPU printing practices.

Tips for perfect prints

  • TPU is hygroscopic – dry before printing (e.g., in a filament dryer).
  • Limit retractions and travel over gaps; increase flow for flexible details.
  • For more pronounced color gradients, choose larger models or “vase mode”.

Applications

  • Protective covers and cases, soft bumpers, cable holders
  • Accessories for sports and cycling, anti-slip elements
  • Decorative models with an eye-catching rainbow gradient

Compatibility

Compatible with FDM/FFF 3D printers using standard filament. (Diameter see technical specifications below.)
