SUNLU TPU 3D Printer Filament 1.75mm, High Speed 95A TPU Filament, 1KG Flexible 3D Filament for Fast Printing, Dimensional Accuracy +/- 0.03mm, Suitable for Most FDM 3D Printers. (Black)

I was a little hesitant to try TPU since flexible filaments can sometimes be tricky, but this SUNLU 95A TPU printed much better than I expected. The black color looks clean and consistent, and the filament came neatly wound with no tangles straight out of the package. What really stood out was how smoothly it printed, even at faster speeds than I normally use for TPU. Feeding was consistent with no jams or bunching, and the dimensional accuracy seems very good. My prints came out clean with solid layer adhesion and nice flexibility without feeling too soft or rubbery. I used it for phone grips, protective covers, and a few small shock-absorbing parts, and it performed great for all of them. The finished prints are durable, slightly flexible, and hold up well to repeated bending. For a 1kg spool at this quality, it’s an excellent value. Definitely a great TPU option for anyone wanting reliable flexible filament that works well on most FDM printers.

This 4kg TPU filament bundle from SUNLU has been excellent for my 3D printing projects. TPU is my go-to material for flexible parts, and this bundle provides great value with multiple colors to work with. The 95A hardness is perfect - flexible but not too soft. The filament quality is consistent throughout the spools. I've been printing on my Bambu Lab P1S, and it feeds smoothly without jamming or under-extrusion issues. The dimensional accuracy of 1.75mm ±0.03mm is spot-on, which is crucial for consistent printing with flexible materials. The variety of colors in the bundle is great - it lets me create different prototypes and products without having to order individual spools. Each spool has printed clean layers with good adhesion between them. The finished parts have excellent flexibility and durability. For anyone regularly printing flexible parts - whether for grips, gaskets, phone cases, or other applications requiring elasticity - this bundle offers great quality at a competitive price. Highly recommend SUNLU TPU filament.

As someone who has been 3D printing for years, I’ve experimented with numerous filaments, this is easily a solid 5 stars. Print Quality: Right out of the box, the filament feels incredibly smooth and consistent. When I loaded it into my 3D printer, I was amazed at how easy it was to get started with no significant issues. The filament fed smoothly into the extruder without any jams, and the prints came out incredibly sharp and precise. I’ve printed several functional parts, including phone cases and mechanical components, and the results were fantastic. The layer adhesion is flawless, and the prints have a very professional finish. Flexibility & Durability: Its a nice floppy but durable TPU, not too rubbery, but enough to easily be able to print some flexible items. Print Settings: For those familiar with TPU printing, you know that it can sometimes be tricky with temperature settings and print speed. However, I found this filament to be quite forgiving. I printed at a moderate 220°C extruder temperature and 50°C bed temperature. It adhered well to both a heated bed and an adhesive surface, with minimal warping or lifting. I did slow down my print speed to around 20-30mm/s, which worked perfectly. The print quality was superb even with these settings. Surface Finish: The finish on prints made with this TPU filament is smooth and consistent, with no signs of stringing or oozing. This is often a problem with flexible filaments, but I didn’t experience any significant issues here. My prints had a nice matte finish, and there was no need for post-processing or sanding to achieve the smooth look I wanted. Value: For the quality of this filament, the price is incredibly reasonable. You get a high-quality product that performs consistently with minimal fuss, making it an excellent choice for anyone looking to print functional parts or high-quality flexible objects. Final Thoughts: This TPU filament has certainly raised the bar for me in terms of both quality and ease of use. Whether you’re a seasoned pro or a beginner looking to dive into flexible 3D printing, this filament is a great option. It provides the perfect balance of flexibility, durability, and ease of use, and the results speak for themselves. Highly recommend it to anyone looking for top-notch TPU filament!

Worked exactly as intended. It was spooled very neatly. I did the suggest 8 hours of drying before using. I had 0 issues with bed adhesion and zero issues with clogging or feeding. I wanted to use Bambu Lab's own but they are never in stock. Sunlu has been a great bang for my buck when it comes to 3D printing.

This TPU prints great. It is a bit hard to get off the smooth cool plate though. Usually need to put a little alcohol on the plate to release the sticky. 4 stars because they could give better colors.

I’ve been using SUNLU’s TPU mainly for printing waterproof gaskets, and it’s been doing exactly what I need it to do. It prints consistently once dialed in, with good layer adhesion and flexibility. The material seals well, which is key for gasket use, and I haven’t had issues with leaks when the design is right. It also feeds more smoothly than some other TPU brands I’ve tried, which makes a big difference on longer prints. Not much to complain about—solid, reliable TPU that gets the job done.

I bought this SUNLU High Speed TPU for some of my more functional custom projects, and it is excellent. Normally, TPU has to be printed very slowly, but this 95A formula works perfectly with the higher speeds of my A1. I print it directly from my SUNLU S4 dryer box, which is a must for TPU to keep it from stringing. The layer adhesion is incredible you almost cannot pull these parts apart. It’s perfect for gaskets, protective bumpers, or anything that needs to absorb impact. If you've been afraid of printing flexibles on a fast machine, this "High Speed" version is the one to get.

Prince Gray, super strong, great option for TPU!

With print profile provided by Sunlu, the print results on Bambulab A1 mini are quite precise with a smooth surface, strong layer adhesion even at high speeds. Also this tpu has allmost no stinging. 30% Cheaper then competitors gives a good price/quality ratio.

Si buscas TPU para proyectos funcionales, especialmente objetos flexibles que necesiten resistencia, este filamento cumple de sobra. Totalmente recomendable.

Mi crealty se tapona mil veces con este filamento

Es plástico con pequeña flexibilidad, en piezas pequeñas se deforman un poco, depende para que lo quieras utilizar, supongo que para algunas pieza puede valer, pero no es como engomada más bien es plástico flexible en piezas delgadas, contra mas gruesa sea la pieza va perdiendo flexibilidad.

I wasted at least 2/3 of the spool because it kept getting stuck. I had to unroll the spool and rewind it. This stuff was tangled through the whole spool.
