Product Details
- 【Ultra Soft & High Elasticity】 YOUSU TPU 85A filament is significantly softer and more flexible than standard TPU 95A, delivering a true rubber-like feel. With an elongation at break of over 600%, your printed parts can bend, stretch, and compress repeatedly without breaking, cracking, or whitening — perfect for functional parts that require genuine elasticity and shock absorption.
- 【High-Flow Formula for Faster Printing】 Unlike traditional flexible filaments that demand painfully slow speeds, YOUSU TPU 85A is engineered with an optimized high-flow blend that enables printing at 50–90mm/s without sacrificing surface quality. The filament feeds smoothly through direct-drive extruders, reducing the risk of buckling, clogging, and stringing for consistent, professional results every time.
- 【Wear-Resistant & Tear-Proof】 Despite its extra-soft feel, YOUSU TPU 85A offers outstanding wear resistance and tear strength. Printed models maintain structural integrity and surface quality even under repeated friction and compression — making it ideal for RC car tires, phone cases, shoe soles, gaskets, and other functional parts that undergo constant wear in real-world use.
- 【Precision Diameter & Broad Compatibility】 Every spool is manufactured to a strict ±0.03mm diameter tolerance with laser-based quality inspection for consistent extrusion. Compatible with most 1.75mm FDM 3D printers, with optimized performance on direct-drive systems including Bambu Lab (X1/P1/A1), Prusa (MK3/MK4), Creality K1 series, and other TPU-capable printers. No special adjustments needed for basic printing
- 【Vacuum-Sealed Freshness & Reliable Support】 Each 1kg (2.2 lbs) spool is vacuum-sealed with a desiccant pack to ensure low moisture content upon arrival. We recommend drying the filament at 50°C for 7–12 hours before printing if exposed to humidity. Recommended settings: nozzle 230–250°C, bed 35–45°C, speed 10–35mm/s. If you have any questions, our customer support team is always ready to help.

Printing Yousu TPU
Yousu TPU in Black 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.
Based on Bambu Lab and Prusa guidance. More in our nozzle types guide.
