SainSmart 1.75mm Flexible TPU 3D Printer Filament 800g Solid Color, Dimensional Accuracy +/- 0.05 mm (Liquid Luster)

Set speed to 40mm/s and 220C nozzle and 50C bed with an 8mm retraction length. Smooth print surface Get the nozzle really close to the bed. First layer with the white needs to look almost clear. Great prints no strings.

I bought this in black and yellow, waiting on the multi-color pack to get back in stock now. I spent a week in hell, as I was new to FLEX and had to learn some things the hard way. Punch line: this is AWESOME filament! The yellow looks like a glowing fiber optic when light is nearby, it is simply marvelous!! They are both extremely strong, but also soft and lustrous. Super elastic. You can take the single skirt extrusion and stretch it to perhaps 10 times it's size without breaking, but the material seems to remain slightly stretched if you do that, perhaps 30-60%, but after that it always snaps back to that size. Ordinary prints are super strong and hold their shape perfectly.Here are the bottom line lessons learned if you are new to TPU: LOOSEN THE IDLER!; start at 15-20mm/s for everything except travel; be certain your 1st layer is dialed in well for this filament; and TURN OFF RETRACTION. TPU will wrap itself around your extruder gear, or jam, and speed and retraction are the enemy here. Get it to print, enjoy how amazing it is and be happy, and optimize from there!I have a Prusa i3 MK3. My original hell began on this, and I naively tried to use the stock profile for Sainsmart TPU (I mean, it was there, right?). It seemed to work, but ended up dying mid print, almost always. Ended up wrapped around the extruder gear. Annoying to open things up and unravel it. Rinse and repeat, no joy. Played with very many settings, read very many blogs. Nothing worked.Finally blew the dust off my MK3S upgrade kit, bit the bullet, and spent a bunch of hours tearing down and rebuilding my extruder. Tried again, this time switching to the much more expensive *good filament* I bought (Ninjatek). IT JAMMED AGAIN. WORSE. OVER AND OVER. Finally, it basically tied a knot around the gear and I had to do a 50% disassembly of the extruder to get it out (luckily the MK3S upgrade anticipates this and it's easy).Ditched the Ninjatek (I really dislike that filament, it's expensive, has a dull luster, is too soft, and even harder to print, what a bunch of overhype!). Read a bunch more blogs, and finally realized the only real problem was trying to use the stock profile. The answer was go extreme at first, and optimize after you are happy and can go from there. Here are the full changes I made to the stock Sainsmart profile to start with:- Everybody says "loosen the idler"....but to what?! I had to loosen the idler almost entirely, for me almost the entire screw head was jutting out, and perhaps 1-2 turns of the screw were in the nut. This is super important, and I found you can find the sweet spot by starting loosest (screw just biting), try to load, and tighten until it loads, then stop! Experiment from there.- Bed Temp 70 deg C- Extruder Temp 235 deg C- All print speeds 15mm/s (keeping fast travel speed seemed fine, if a little stringy)- Turned off "keep fan always on"- Enabled auto cooling- Turned off retraction! (in Prusaslic3r this is in the printer settings tab under Extruder 1)I have so far turned the speed up to 35mm/s for infill and it seems to work fine, others say 40mm/s works.I love this filament. After a week of misery, once tuned in it just works every time, good luck!

My first time printing TPU with my FLSUN V400, and this filament worked great at 220C. The end product was not as squishy as I had expected, but the Yellow transparent color is incredible, and pieces really fluoresce brightly under just a little UV light.

I bought some TPU from them and originally it printed great. Soon after the material was printing terrible. I contacted customer service as soon as I started to dry the material. They were very responsive an offered a replacement spool but once the material was dried it printed great. I would buy from them again in a heartbeat (Sainsmart).

Always consistent size and quality. It’s my go to filament for TPU!

I'm choose the Sain Smart TPU sure to the reviews on Amazon. In general, my printer is dialed in very well. I have a QIDI X-Max II. The detail in the print is as good as PLA prints, but that where the similarities end. TPU is a very flexible material good for phone cases, watch bands, etc. The Sain Smart printer does give excellent results free from stringing, it has excellent layer adhesion and comes off the printer with minimal post print work needed. I will buy again if I need more TPU in the future.

It's nothing to dislike, once you have your printer set it's a piece of cake. Here is set I use cura tpu set up, only use sainsmart because of the heat to work is 210 to 220 and when you use cura tpu set it set to 228 which is what give excellent prints every time.

Absolutely nothing wrong with the product. Very well made TPU filament in fact. My issue is related to how the listing says "Orange" but you are actually buying "Translucent Orange". One has to scroll all the way to the bottom before seeing anything detailing translucent. I contacted support and was told that the opaque orange is called "Mango Mojito". In my mind when I see a listing Orange means Orange so I didn't think twice about it. I'm taking away one star because of the misleading listing. In the end it's taken my time to correct it.However, if anyone wants to know, Customer Support is on point with SainSmart. That's why they're getting a positive review here. Very professional and it's clear that they care about their customers. SainSmart is going to update the Amazon list to say "Translucent" in the title so nobody else has this issue, and they worked with me to sort out a replacement. Thank you!

Gave to a friend , have no idea how good or bad as 3D printing goes but items printed look good.

This is my new favourite filament. First time printing with TPU and I'm amazed at the ease and quality at which this prints. I highly recommend this filament. I'll definitely be ordering more.

Pas facile à imprimer (cheveux d’ange) mais pas de bouchage de buse. Température 210°c et 20mm/s. Globalement positif sauf le côté pailleté/brillant qui n’était pas précisé.Mise à jour: aprés avoir correctement réglé la sonde de tempétature de mon extrudeur, je n’ai plus de cheveux d’ange.Pour le côté brillant/pailleté du filament, aprés un premier contact par le vendeur afin de trouver une solution, il m’a offert un remboursement. SAV d’excellente qualité qui cherche à nous aider.

Tpu fantastico, sainsmart una garanzia. Avevo già avuto modo di provare la qualità di questi filamenti, ma questo nero è incredibile 😍. Lucido, facile da stampare, resistente e bello flessibile, perfetto per i miei droni fpv e parti per moto. Assolutamente consigliato.
