Product Details
- 1KG 95A Flexible TPU Filament: Upgraded to a 1KG spool, this TPU combines extended printing capacity with 95A Shore hardness, delivering a reliable balance of flexibility and structural strength. Ideal for functional parts requiring both durability and elasticity, such as phone cases, wearables, insoles, and protective components
- Strong Layer Adhesion Performance: Engineered for stable extrusion and strong interlayer adhesion, helping produce smoother surfaces, improved structural integrity, and reduced print defects across both small and large models
- Moisture-Protected Vacuum Packaging: Each spool is thoroughly dried and vacuum sealed with desiccant, minimizing moisture-related issues such as bubbling, stringing, or clogging—resulting in a more consistent and reliable printing experience
- High Precision: Manufactured with tight tolerances at 1.75mm ±0.05mm, ensuring even filament flow, reduced risk of jams, and stable performance during extended print jobs
- Multiple Color Options for Applications: Available in Black, White, Blue, and Red, supporting both functional and aesthetic printing needs. Different colors are suitable for technical prototypes, product design validation, and personalized creative projects, enabling clearer part distinction and more flexible application scenarios

Printing SainSmart TPU
SainSmart TPU in Blue runs on the TPU profile below, and this listing is a 1kg spool. TPU is best suited to flexible, rubber-like parts such as phone cases, gaskets, and vibration dampers. Brands and even individual spools vary, so treat these as starting points and run a quick temperature tower to lock in the sweet spot for your printer.
Ranges checked against Bambu Lab and Prusa data. Heat resistance is the heat deflection temperature (HDT). Read our TPU filament guide for bed adhesion, drying, troubleshooting, and material-specific tips.
Nozzle Compatibility
Flexible filament is not abrasive, so brass and hardened steel both work. Size matters more: the higher pressure in a small nozzle makes soft filament buckle in the extruder.
