Bambu Lab TPU 85A Flexible 3D Printing Filament Neon Orange (51305) – 1.75mm Ultra-Soft TPU

Product Description

Bambu Lab TPU 85A Flexible 3D Printing Filament Neon Orange (51305) is an ultra-soft thermoplastic polyurethane filament developed for applications where maximum flexibility, impact absorption, and wear resistance are essential. As the softest TPU offered by Bambu Lab, TPU 85A is specifically engineered for elastic, shock-absorbing, and vibration-damping parts that must endure repeated bending and mechanical stress.

This filament is ideal for engineers, product developers, and advanced makers in Bangladesh who require reliable flexible filament for functional prototypes and end-use components. With precise 1.75mm diameter control and consistent material quality, it delivers smooth extrusion and dependable print results on compatible FDM 3D printers. TPU 85A supports multi-material printing with PLA and PETG, enabling complex assemblies and flexible-rigid part combinations. Supplied on a high-temperature reusable spool, it offers long-term value and professional-grade performance for demanding flexible 3D printing applications.
