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)

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!

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.

This was my first try with TPU printing and it went off without a hitch. I use the K1C and a creality dryer and had no problems with this filament. All I did was adjusted the settings in the printer app to TPU and BAM started printing. It isn't as shiny as it looks but does have a little shine to it. I have printed a lot of things and still have a lot left I need to find projects for. It seems to have great quality (again my first TPU) and the prints are not brittle and have flexiblity. I will be buying more colors to try out.

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.

Parfait sur Prusa.

Ich bin sehr zufrieden mit dem Filament es lässt sich sehr gut drucken!
