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

• 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.

Siraya Tech TPU Air – The Future of Lightweight, Flexible 3D Printing. Built on our proven 85A TPU formula, Siraya Tech Flex TPU Air is an innovative active foaming filament that puts you in total control. By simply adjusting your print temperature, you can dictate the hardness, weight, and texture of your final print. This next-generation material reduces weight by up to 50%, offering an unparalleled combination of flexibility, strength, and low weight. Why Choose Flex TPU Air?
Incredible Value: Each roll contains a full 1kg net weight, giving you significantly more material than the 750g rolls commonly sold by competitors.
Prints Like a Dream: Because the foaming activates at the nozzle, the filament stays rigid in your extruder. This eliminates the frustrating clogs and feeding issues usually associated with printing 65A-75A flexible materials.
Skin-Friendly Finish: Creates a soft, shock-absorbing, fabric-like texture perfect for wearable medical supports, insoles, grips, and phone cases. Key Benefits:
Dynamic Hardness Control (65A-82A): Adjust print temperature for precise softness.
50% Weight Reduction: High foaming at elevated temperatures for ultra-light prints.
