SainSmart101-90-158 White Flexible TPU 3D Printing Filament, 1.75 mm, 0.8 kg, Dimensional Accuracy +/- 0.05 mm

I have been getting the neon yellow TPU material for years and it has never had a knot and never given me print issues. I use it in my combat robots and it holds up great.

Good product.Okay... first time printing TPU after using PLA exclusively. On the first few attempts, I had adhesion issues like everyone else here. Even cleaning the bed with rubbing alcohol between prints didn't do the trick (I always do this whenever my fingers touch the bed). Adhesion is easily fixed with the right settings.I'm using a 0.5 mm nozzle to print some tubular adapters, so I care more about function than things looking pretty, but the settings should translate to other nozzle sizes too. Here's what I'm doing:* Printer: Ender 3 v2What I find makes or brakes this TPU:* Nozzle temperature: 200 C (anything hotter, even at 210 C, the filament starts looking "bubbly" and unclear/cloudy rather than smoothly transparent; I can probably lower it to 190 for even more clarity - see picture for what I mean)* Bed temperature: 50 C (cooler bed seems to perform better, anything hotter and I get bad adhesion)* Initial layer speed: 10 mm/s (first 6 layers are at this "slower" speed, # can probably be reduced to like 2-3)* Speed: 30 mm/s (max, I typically reduce this even more down to like 50% i.e.15 mm/s)* Wall speed: 15.0 mm/s* Cooling: from 50% to 70% during the first 4 layers, then 70% for the rest (I tested starting at 0%, which made the bottom layers look way off compared to the rest of the print)* Retraction: 6.5 mm @ 25 mm/sWith TPU being so "stretchy" compared to PLA, I think some retraction is necessary regardless of what I read online. I haven't tried it without, as even with retraction there is some "smearing" / trailing happening, but it's very minimal and hasn't impacted the structural / look of my pieces.Other print settings I'm using that may have an impact:* Layer height: 0.25 mm across the board* Line width: 0.5 mm across the board* Wall line count: 3* Top/bottom layers: 4* Infill: 50% (for my use case)This works for me, adhesion is no longer an issue, no need for tape or whatever other hacks are suggested out there. Just lower your temperatures a bit and it will work great.Hopefully this helps everyone having issues.

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!

I used this filament for table legs and it prints really well! At 230 there is no bubbling and layer adhesion is great. (stock creality k1 at 230c, otherwise default tpu settings)

perfecto como siempre!
