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 clogs, and more finished parts.
Built for Real-World Use
Flexible parts are often worn, bent, or dropped.
Skin-friendly texture for wearables
Excellent impact resistance
Durable and bendable without cracking
Suitable for medical accessories and supports
Designed for repeated flex and load
Use this breathable flexible filament for wristbands, straps, grips, and sports padding. Create performance TPU material parts that feel comfortable and stay reliable over time.

TPU air filament is a foamed TPU material that expands during printing. It creates a lightweight TPU filament with a softer feel. By adjusting print temperature, you can control hardness and density. It works well for cushioning TPU and shock-absorbing filament applications.
How is air-infused TPU different from regular TPU?
Air-infused TPU contains active foaming agents that create a low-density flexible filament with less weight. Regular TPU stays solid and heavier. Foamed versions offer more comfort and better impact absorption for wearables and protective gear.
Is TPU air filament hard to print?
Most modern FDM printers can handle it with direct drive extruders working best. It offers stable extrusion and good bed adhesion. Proper temperature settings help control expansion and finish, making it easier to work with than you might expect.
What can I print with lightweight TPU filament?
You can print insoles, grips, straps, vibration dampers, and protective covers. It works well for sports-grade TPU filament needs like padding and supports. Many users choose it for wearable devices, phone cases, and flexible medical accessories.
Can I control the softness of foamed TPU material?
Yes. Higher print temperatures activate more foaming, making parts softer and lighter. Lower temperatures create denser and tougher prints. This allows you to tune performance TPU material to match your specific project requirements.
