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)

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!

Why did you pick this product vs others?:I bought this to see if my current machine was capable of printing TPU at a higher speed. The material is very forgiving of temperature as a temperature calibration tower showed almost no difference between the highest and lowest recommended temperatures. Next I printed 20x20x20 calibration cubes to dial in the speeds/feed. I was able to go just above the recommended rate to 130 mm/s. When I attempted to build larger things, the machine could not deliver enough material and I had to slow the feed down to 90 mm/s. This is still amazing because it is still 10x faster than older TPU would print.

This filament prints almost as easily as PLA, is odorless and gave me good results. My main emphasis is on functional prints like caps for my astronomy gear, and this filament is great. I like brilliant yellow, so I can find a cap I drop in the dark or at the bottom of a dark bag. LOL The filament does need to be dried before printing, but after that, it worked with a combination of the default settings (pressure, retraction, etc.) of my Bambu Lab A1 and the temperature ranges from Sunlu.I got a little very fine stringing on the collet for my eyepiece holder in the photo that could be fixed with some changes, but I didn't bother. The two caps came out just as I needed - The outer cap is slightly smaller than the thread diameter and the inner one slightly larger so they slide in and grip the very fine threads that don't print well. I've had them on the scope for a few trips, but they work great and have just enough flex to work exactly as I want. Unlike the really squishy prints the collet had 35% infill and the caps had 4 surface layers (top & bottom), which gave a good combination of strength and flexibility. I'm very happy with this filament, especially since it was my first try with TPU!

My studio tested this product out and print quality is by far exquisite quality low to no clogging packaging well done. We like the resealable bag with it as well.

Filament itself seems fine. I think they changed the plastic spool. For some reason they put a small notch in 1 side along the edge. Not an issue if you hang your filament from the inside of the spool, however if you put it in a heater/roller thing that expects it to be a perfect circle to roll/feed while resting along the edge of the spool, note that you'll need to take some tape and make this notch flat so it can spool.My first several prints kept "clogging" but I found it was actually that the spool worked fine until it got to this notched point and then it would "stick"/refuse to rotate anymore and the printer would fail to pull more filament. Annoying they did this at all, but after pulling the filament myself a bit, it became obvious what the issue was.

It was my first time printing with TPU and let me tell you it was absolutely AMAZING! It printed so well I dried it before use and I had no issues the laters were amazing and looked so good printing on my X1C. I printed it the way Bambu recommend too. Sunlu makes great filament.The only issue I encountered was the reusable filament spool it was on was loose and when I grabbed it it broke apart. The way the filament is so flimsy it wasn't an issue. I put it back together and glued it. Other than that I highly recommend this filament.

havent tried yet but good brand

Every single roll looks like it was wound by an infant. All 8 rolls are poorly packaged. If the return policy wasn't a scam I would request a full refund. This should never have passed quality control. This makes you question the price after receiving trash like this. This causes a delay and money lost for people when Amazon clearly isn't who there were and don't vet sellers before they sell trash.
