Is SUNLU TPU Filament 1.75mm worth it?
A top pick in Additive Manufacturing Products on Amazon (#11 when we checked, Nov 7, 2026)
Worth it if you want a flexible 95A TPU filament for compatible 1.75mm FDM printing, especially for parts that need elasticity, wear resistance, and a black 1kg spool. The listed 210-230°C nozzle range and 80-120mm/s speed target make it a practical choice for flexible projects.
Good to know: If you need rigid parts or a filament outside 1.75mm TPU printing, look for a material matched to that job and printer setup.
Flexible TPU filament for faster, more forgiving prints
Your hands will find the corner a filament cuts, especially when a flexible part needs to bend without turning soft and floppy. SUNLU TPU Filament 1.75mm uses 95A thermoplastic polyurethane, giving the printed material flexibility with a firmer feel than very soft TPU. That suits parts for flexible applications, robotics, fashion projects, and everyday wear and tear.
The useful design choice is the stated balance between flexibility and resilience. Because the material is flexible, a printed part can handle bending and collisions differently from a rigid filament. SUNLU also lists wear resistance, oil resistance, and elasticity as material properties, while the buyer overview describes the filament as nicely flexible without being too rubbery. That gives you a clear lane for the spool: functional flexible parts rather than ordinary rigid models.
The listing recommends 210-230°C at the nozzle, 50-60°C on the bed, and 80-120mm/s printing speed. It also lists 1.75mm diameter with dimensional accuracy of +/- 0.03mm and says the filament suits almost all 1.75mm FDM printers. Check your printer's material compatibility before ordering. The spool is vacuum packaged, so it reaches you sealed against moisture from the factory.
You get one 1 kg spool of flexible 95A TPU, enough material for repeated flexible projects rather than a one-off trial. The stated 1.75mm format and recommended settings also give you a clear starting point for setup.
Great for
- Flexible parts for compatible 1.75mm FDM printers
- Robotics and wearable project components
- Fashion projects needing elastic printed material
- Makers wanting a 1kg black TPU spool
- Prints exposed to everyday wear and handling
Maybe not for you if
- You need rigid PLA, PETG, or another non-flexible material
- Your printer does not support 1.75mm TPU filament
- You need a color other than the listed 1kg black spool
SUNLU TPU Filament 1.75mm is a sensible pick for makers who want flexible black parts from a compatible 1.75mm FDM printer. Its 95A hardness gives you elasticity without the listing's described overly soft or rubbery feel, while the recommended speed range supports a quicker starting profile than ordinary TPU. The 1 kg spool, vacuum packaging, and stated dimensional accuracy add practical value. Choose it for flexible applications, robotics, fashion projects, and wear-focused prints where TPU is the right material. Your hands will find the corner they cut, so check fitment first.
