Excellent Flexible Filament with Outstanding Print Quality
Color: 1kg Black
I've been extremely impressed with the SUNLU TPU 95A Filament. TPU can sometimes be challenging to print, but this filament made the process surprisingly easy. The filament feeds smoothly, maintains consistent extrusion, and produces clean, high-quality prints with excellent layer adhesion. The flexibility is exactly what I was looking for. Finished parts are durable, resilient, and have a great balance between softness and strength. I've used it for protective covers, gaskets, and functional components, and the results have been fantastic. The 95A hardness provides enough flexibility without feeling too soft or difficult to work with. Another standout feature is the high-speed printing capability. Compared to other TPU brands I've used, this filament handled faster print speeds remarkably well while still maintaining strong layer bonding and sharp details. The black color also looks great, giving finished prints a clean and professional appearance. The spool arrived well-packaged, vacuum-sealed, and neatly wound, with no tangles or feeding issues. Consistent quality from start to finish made long print jobs stress-free. If you're looking for a reliable TPU filament that offers excellent flexibility, durability, and printability, this SUNLU 95A TPU is an outstanding choice. Highly recommended for both TPU beginners and experienced 3D printing enthusiasts. Great value, great quality, and excellent results!

Great flexible TPU
Color: 1kg Black
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!

Durable and Beautiful
Color: 1kg Clear Blue
I've always loved the PLA from brands like Sunlu and eSun.. I figured I'd try Sunlu's TPU... This is my first time printing with TPU. From what I've heard, TPU is not terribly difficult to work with, but is prone to stringing because of the elastic nature of the material... This stands true, as far as I'm aware, because when I tried a flow rate calibration with straight lines they all just looked the same, even though there was variance in the numerical values. So, if you're trying to fine tune this stuff to be perfect, good luck! So far the only things I have printed out of this TPU have been: a squeegee fluid clearing blade, Pastamatic filament re-spooling dampers, an 'airless' ball, and some AR style mag pulls. The squeegee fluid clearing blade works great. Not too bendy, not too stiff. The ball was more firm than I expected, and required quite a lot of strength to compress, even though the model was pretty light on walls and infill. Since the spool dampeners on the pastamatic machine are a consumable wear item made to be worn down and drag along a spools sides, to prevent back-feeding or unspooling, I can't really give it a grade on durability... Just depends how fast you run your machine... But, I can say that I noticed grooves after just 2 uses - but i was running the machine at full drill speed. Lastly, the magazine pulls - aka ranger loops - They are surprisingly durable and the layers are well fused. This was kind of the real-world durability test of this filament for me. This TPU material is super grippy, and doesn't slide off anything easily, even when it's TPU on nylon polymer composite plastic. I was pulling on both ends with all my strength after putting the item on, for its intended use, and the material never slipped off the item, and the material never de-laminated or broke in any way. To say that I was impressed was an under-statement. This material is very well put together to fuse and hold shape. It is very bendy and flexible in some applications, when done correctly on small thin items, and in others like larger & midsize objects its quite firm. On top of all that, it's a great value, and looks amazing. The clear blue color is perfect. I'm very grateful that this comes on a plastic spool. Yes, it does look a little messy on the spool, but it's TPU - It doesn't have to be wound tight and held that way. As one normally should do when receiving filament, I immediately put it in my filament dryer after unpacking before any printing was attempted. If you do want to get the true TD value and HEX color values of this filament, good luck - but, I'll share what I got here: Each attempt separated by a comma - TD: 20.8, 21.1, 23.3, 20.1, 25.4 HEX color code:154BA4, 1953DB, 1850B3, 164DAD, 1751B5 Naturally, I'm obligated to remind people of the filament they're looking at and what to expect -- This is a TRANSPARENT filament. You're not going to get an accurate TD or color reading from it. Expect some variance! Best you can do is a ball-park number/code and program it the best you can into whatever you're working on. Check out the photos and video provided, please.

Excellent TPU filament — flexible, strong, and surprisingly easy to print
Color: 1kg 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.

A good tpu filament
Color: 1kg White
The sunlu brand has been my go to for the past year or so and I've gotten pretty decent results with it. Just make sure to tune it correctly and dry it. This paired with a sunlu dryer is perfect. Color is true to picture, prints easily if correctly set, this tpu is pretty good for elastic things or things that need to endure hits

Good quality TPU, just expect some stringing
Color: 1kg Black
I've tried several budget filament brands, and SUNLU continues to be one of my favorites. Their TPU offers great value without feeling like a cheap product. The filament has a nice, consistent black color, and once printed, it has the flexible rubber-like feel you'd expect from a quality 95A TPU. My prints have come out clean with good layer adhesion and no issues feeding through my printer. The only downside I've noticed is that it can be fairly stringy, which is pretty common with TPU. It usually isn't difficult to clean up, but it's something to expect if you're printing detailed models or parts with a lot of travel moves. Overall, this is one of the better TPU filaments I've used in this price range. If you're looking for an affordable TPU that prints well and has a great finish, I'd definitely recommend giving it a try.

Gets the job done
Color: 1kg Black
For what I'm doing it's completely fine. I can't really blame the filament. It's 80% humidity outside, and inside isn't much better. That being said, it held up ok. If you're careful about pathing in your slicer software, you can get away with not a lot of stringing. Always use "avoid crossing walls" with a massive margin and you'll probably be ok. I see a lot of pictures with people complaining about the spaghetti nature of the filament on the spool, but it's fricken rubber in a string format 😅 what did you expect. It hasn't effected my prints in the slightest. It adheres to the print bed at a pretty low temperature which is cool. If your using direct drive you can probably print at a pretty high temp and print with a faster max volumetric rate. I'm using 10mm3 and I haven't had any clogs yet, even though the "generic TPU" preset started at 3mm3. Pretty cool stuff. It has really opened the door for some crazy projects.

Just works.
Color: 4kg Black+black+black+black
Great stuff - prints with default TPU settings from bambu. No issues with using it as an external mount - cold pulls well and then just works for many prints without issue. I've only bought the black so far but seems consistent for color between reels. Good price for a 4 pack; looking forward to making many more things.
