Adjustable Hardness & Softness: Flex TPU Air filament allows dynamic control over hardness from 65A to 82A by adjusting the printing temperature. Lower temperatures yield tough, durable parts, while higher temperatures activate foaming for a lighter, softer feel.

Up to 50% Weight Reduction: Featuring advanced active foaming technology, TPU Air 3d filament achieves significant weight savings while maintaining excellent elasticity and toughness, perfect for lightweight applications requiring durability.

Comfortable Fabric-Like Texture: The printed surface has a unique soft-touch feel, making it ideal for wearable devices, grips, and protective cases that require direct skin contact.

Optimized for Easy Printing: TPU Air utilizes active foaming technology. The unactivated foaming component is evenly distributed within the filament. This results in the filament maintaining better hardness compared to passive foaming materials, which results in easier filament transportation and printing. The filament density is also maintained. Compatible with most FDM printers, it supports extrusion flow rates up to 12mm³/s for fast, smooth printing.

Versatile for Various Applications: Ideal for sports gear, insoles, grips, wristbands, protective cases, soft toys, and medical support devices, Flex TPU Air 3d printer filament brings flexibility and lightweight performance to functional and creative projects.
