Product Details

  • ADJUST HARDNESS WITH TEMPERATURE (75A-95A): Dial in your perfect flexibility with a single roll of filament. Print at lower temperatures for a tough, durable 95A finish, or increase the heat to activate the foaming process for a noticeably softer, lighter 75A feel.
  • UP TO 50% LIGHTER WITH ACTIVE FOAMING: Achieve massive weight savings without sacrificing elasticity or toughness. Perfect for RC parts, drones, cosplay, sports gear, and any application where lightweight durability is critical.
  • EASY, CLOG-FREE PRINTING: Stop fighting your extruder. Our unactivated foaming component keeps the filament rigid before it hits the nozzle. This makes feeding incredibly reliable compared to passive foaming or ultra-soft filaments. Supports flow rates up to 12mm³/s for fast, smooth printing on most FDM setups.
  • COMFORTABLE, FABRIC-LIKE TEXTURE: The foaming process creates a unique, premium matte surface with a soft-touch feel. It is ideal for skin-contact applications like wearable devices, watch bands, custom grips, insoles, and protective cases.
  • Full 1kg Spool (Net Weight): Every single roll of Siraya Tech Flex TPU Air 95A delivers a full 1kg of premium specialized flexible filament. This ensures extended, uninterrupted printing time for your large-scale engineering or creative projects without the need for frequent spool changes.

Printing Siraya Tech TPU

Siraya Tech TPU in Black runs on the TPU profile below, and this listing is a 1kg spool. TPU is best suited to flexible, rubber-like parts such as phone cases, gaskets, and vibration dampers. Brands and even individual spools vary, so treat these as starting points and run a quick temperature tower to lock in the sweet spot for your printer.

Nozzle Compatibility

Flexible filament is not abrasive, so brass and hardened steel both work. Size matters more: the higher pressure in a small nozzle makes soft filament buckle in the extruder.
