Features:

• [Customizable Softness & Hardness (77A93A)]: Want your prints tough or soft? Flex TPU Air lets you control hardness by adjusting temperature and speed. Lower temperatures yield durable, strong parts; higher temperatures trigger foaming for lighter, softer prints
• [Super Lightweight]: Thanks to advanced active foaming technology, Flex TPU Air can expand up to 172% in volume while staying strong and elastic. Compared to regular TPU, it reduces weight by up to 50%, meaning 1 kg of TPU Air prints the same volume as 2 kg of standard TPU. Perfect for large models, cushions, or wearable items without the usual bulk
• [Bounce Back Instantly]: Flex TPU Air springs quickly return to their original shape after compression. Ideal for shoes, wristbands, sports gear, or any project that needs soft yet durable performance. Your parts stay flexible and comfy even under stress
• [Smooth Matte Finish]: Say goodbye to rough layer lines! Prints have a premium matte surface and a soft-touch feel, perfect for grips, protective cases, or anything that touches skin directly. Comfort meets style in every print
• [Versatile for Various Applications]: Flex TPU Air 3D printer filament is perfect for a wide range of projects. Whether youre printing sports gear, insoles, grips, wristbands, protective cases, soft toys, or medical support devices, it delivers lightweight, flexible, and resilient performance for both functional and creative designs. Ideal for DIY makers, wearable tech, and professional applications alike
