Our take

TPU opens up flexible prints — phone cases, vibration dampers, wheels, gaskets. SUNLU's 95A shore hardness is firm enough to print on a direct-drive machine without a fight, making it the easiest entry into flexibles.

What we like

  • Firm 95A prints easier than soft TPU
  • Great for cases and gaskets
  • Good value
  • Durable, abrasion-resistant

What to keep in mind

  • Bowden setups struggle with it
  • Must print slow
  • Absorbs moisture quickly
Best for: First-time flexible printing on a direct-drive printer.
