Siraya Tech Flex TPU Air - Active Foaming 3D Printer Filament, White, 1kg

Product Details

• ADJUST HARDNESS WITH TEMPERATURE (65A-82A): Dial in your perfect flexibility with a single roll of filament. Print at lower temperatures for tough, durable parts, or increase the heat to activate the foaming process for a noticeably softer, lighter 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.
• 1KG SPOOL (MORE VALUE): Every spool of Siraya Tech Flex TPU Air contains a full 1kg (2.2 lbs) of filament, providing ample material for continuous printing and large-scale projects.
