About

TPU air filament from Siraya gives you lightweight flexibility without giving up strength. Our collection is built for 3D printing users who want softer, lighter parts that still last. You get air-infused TPU and other performance TPU material options designed for speed, comfort, and durability. Ideal for insoles, grips, wearables, sports gear, and impact parts. Easy to print. Reliable results. Made for real-world use. If you need cushioning TPU that does not feel bulky or heavy, this is where to start. Options That Match Real Needs Different projects need different levels of softness and strength. Adjustable hardness from soft 65A up to firm 95A and beyond Foamed TPU material for low-density flexible filament prints Solid flexible options for higher load parts Sports-grade TPU filament for active use Expanded TPU and air-infused TPU for weight savings Fine-Tune Feel and Performance Print at lower temps for denser, tougher parts. Raise temps to activate foaming and reduce weight. Get the balance of softness and durability your design needs. Consistent Quality That Delivers Better Results Flexible prints should not fail under stress. Up to 50 percent weight reduction with active foaming Shock-absorbing filament for impact protection Strong layer bonding and low warp Smooth surface finish with soft-touch feel High flow design for faster print speeds This lightweight TPU filament keeps elasticity while reducing mass. Parts feel lighter in hand but stay tough under pressure. Perfect for cushioning TPU insoles, vibration pads, and protective covers. Works with What You Already Use You should not need a special setup to print flexible parts. Compatible with most FDM 3D printers Optimized for direct drive extruders Stable extrusion up to high flow rates Good bed adhesion and low odor Moisture-resistant packaging for long shelf life This low-density flexible filament feeds smoothly and supports faster printing than many standard TPU materials. That means less tuning, fewer
