SUNLU TPU 95A Flexible 3D Printer Filament - Black, 1.75mm, 1kg
SUNLU TPU 95A is a flexible 3D printer filament with a Shore hardness of 95A - soft enough to bend, stretch and absorb impacts, stiff enough to print as easily as PLA on almost any 1.75mm FDM printer. This 1kg spool of black TPU is the go-to material in Indian homes, workshops and engineering labs for parts that need to flex rather than snap: phone covers, gaskets, wheels, bumpers, drone mounts and vibration-damping feet.
Every spool is produced with laser-monitored diameter control and held to a tight 1.75 ± 0.02 mm tolerance, keeping extrusion smooth and consistent through long prints. SUNLU's fully automated winding lays the filament 100% neatly on the spool - no knots, no tangles, no mid-print failures.
Key Features
- Flexible and tough: Shore 95A hardness with over 900% elongation at break - parts bend, stretch and spring back without tearing.
- Impact and abrasion resistant: absorbs shocks and resists wear, chemicals, grease and UV for long-lasting functional parts.
- Easy to print for a flex: prints on direct-drive and Bowden printers with standard settings - no enclosure needed.
- Precise 1.75 ± 0.02 mm diameter: laser-monitored consistency keeps extrusion smooth and layers even.
- 100% neatly wound: SUNLU's automated spooling prevents knots and tangles that ruin long prints.
- Wide compatibility: works with 99% of 1.75mm FDM printers - Bambu Lab, Creality, Anycubic, Prusa, Elegoo and more.

Good to know
- Print slower than PLA (50-80mm/s) and keep retraction low for clean results. A direct-drive extruder makes TPU easiest, but Bowden setups work with slower speeds.
- TPU absorbs moisture faster than PLA. For the best surface quality, dry the spool at 55-65°C for 4 hours before printing, and store it sealed with desiccant.
- A PEI sheet or glue stick helps both adhesion and easy release of flexible parts.
