SUNLU TPU 95A Black Filament — 1.75mm, 1kg, High-Speed Flexible TPU for FDM 3D Printing
Product description
What it is
SUNLU TPU Filament 95A in black is a flexible 3D printing material designed for use with most 1.75mm FDM printers. With a Shore hardness of 95A, it sits in the firmer end of flexible filaments, offering a balance of softness and resilience. The 1kg spool (1000g) is standard for hobbyists and small workshops, and the filament is advertised as capable of faster print speeds without sacrificing print quality.
How it performs on paper
On the sheet, this TPU claims faster printing than typical TPU filaments—up to about three times the speed—while maintaining good layer adhesion and wear resistance. The diameter tolerance is stated at ±0.03mm, which supports reliable feeding and dimensional accuracy across prints. Recommended settings suggest a nozzle temperature around 210–230°C and a bed temperature of 50–60°C with print speeds of 80–120mm/s.
What stands out
The combination of a relatively high speed for a flexible material and a stated 0.03mm dimensional accuracy is notable for users who want quicker, more forgiving prints without frequent reprints due to warping or layer separation. The material is described as wear- and oil-resistant with good elasticity and anti-ageing properties, and the black colour helps with hiding imperfections on visible parts.
Best use cases
This filament is well-suited for everyday flexible parts that need a blend of durability and formability: keyrings, insoles, phone cases and other handheld accessories. These applications benefit from the material’s elasticity and resilience while still being printable on a broad range of 1.75mm printers.
Limitations and caveats
Interpretation matters: the claim of “fast printing” is subject to printer capability, feeder reliability, and calibration. TPU can be tricky if a printer struggles with retraction, oozing, or poor bed adhesion. While the diameter tolerance is small, users with extremely tight tolerances or critical-fit parts should verify each batch before committing to high-stakes prints.
Who it’s for
If you prioritise somewhat higher print speeds from a flexible material and want a budget-friendly 1kg spool for prototyping or light-use parts, this SUNLU filament could fit. It’s less ideal if your priority is ultra-high precision or jewellery-grade finishes where tiny dimensional deviations would be critical.
Who it isn’t for
Not ideal if you require rigid parts, very high-temperature resistance, or prints where the surface finish must be flawless straight off the printer. Also, if your printer has known feeding issues with TPU at very high speeds, you may need to experiment with slower settings.
What to review before buying
- Confirm your printer’s TPU handling capacity, especially with retractions and extrusion pressure.
- Check bed adhesion options for flexible filaments (adhesive sprays, blue tape, or PEI sheets).
- Validate the target part’s required elasticity and dimensional tolerance against the stated ±0.03mm.
- Plan for post-processing steps if you need a polished surface on flexible components.
Practical example of use
Imagine printing a soft yet functional phone sleeve: you’d likely start at 210–220°C nozzle, 50–60°C bed, and 90–110mm/s to balance edge clarity with speed. The result should show decent layer bonding and a surface that’s comfortable to the touch, without visible blobbing if the printer is well-tuned.

FAQ
- Is 95A considered flexible? Yes, 95A is on the firmer end of flexible 3D printing materials, offering resilience with some pliability.
- Can I print fast with TPU 95A? The product promotes high-speed printing, however, achieving consistent results depends on your printer and calibration.
- Will this fit all 1.75mm printers? The stated tolerance supports broad compatibility with most 1.75mm FDM printers, though individual machines may vary.
Final decision
Final verdict
If you need a printer-friendly TPU that aims for higher throughput without a drastic drop in print quality, and you’re prepared to dial in the settings for your specific printer, this SUNLU 95A black TPU 1kg spool offers a practical balance for day-to-day flexible parts. It may not be the best choice if you require ultra-precise fits or high-end surface finishes straight from the nozzle.
