説明
Roamr TPU Air HR 80A is a professional-grade structural foaming filament engineered specifically for footwear comfort and cushioning.
It bridges the gap between experimental materials and production-ready shoes, offering a perfect balance of soft impact absorption and reactive energy return.
Not just soft—but supportive for every mile.
Applications of TPU Air HR 80A
Midsoles
Insoles
Slides/Slippers
Comfort Liners
High-Rebound Resilience
Specificallytunedforfootwear,itoffers48%–50%resilience,providinga"bounce"thatoutperformsstandardfilaments.
Ultralight Active Foaming
Achieve a 50% weight reduction. Create "air-infused" structures that feel weightless without losing structural integrity.
Controllable Hardness (64A—80A)
Control the "squish" via temperature. Dial in softer zones for the heel and firmer support for the arch in one print.
Premium Fabric-Like Texture
No more "cheap plastic" feel. The foamed surface provides a high-end, production-ready textile finish.
Shock Absorption & Anti-Flattening
Absorbs heel-strike impact while maintaining its shape over time—avoiding the "flattening" common in cheap foams.
Universal Compatibility ＆ Rock-Solid Reliability
Extensively verified for both enclosed and open-frame FDM printers, ensuring stable, hassle-free extrusion and repeatable results for every project
