Siraya Tech TPU Air - The future of lightweight, flexible 3D printing. The Siraya Tech TPU Air is an innovative active foaming TPU filament that allows users to adjust hardness, weight and texture simply by changing the print settings. Built on our proven 85A TPU formula, this next generation material reduces weight by up to 50%, offering an outstanding combination of flexibility, strength and low weight. Each roll contains a net weight of 1kg, which gives users more material compared to the standard 750g rolls for similar filament types.
This breakthrough filament is perfect for applications that require soft, skin-friendly surfaces, shock absorption and light durability - from sports equipment and protective cases to portable medical supports. TPU Air easy-print formulation ensures reliable performance on most FDM 3D printers with high-speed extrusion functions.
