PolyFlex™ TPU90

First time using TPU. It worked well. I didn't do anything complicated. The first print the seam was a bit pronounced, but after that it was much better. It is a nice color, and so far holding up well. I used it as a boot on a stainless water bottle.

Wanted a flexible filament a little softer than 95A. This TPU delivers! The color is great and it prints relatively easy. I took one star off because it didn't print very smooth, despite being bone dry. It may be user error and it could be I need to tweak the settings.

Prints wonderfully

Not tried it been waiting for p2s combo for 5 wks

Consistent color over the years. And great print quality I have printed on an ender 3, century carbon, and H2C with this tpu and have been very happy with the results.

This functional PLA is a dream to work with.
Thanks for making such a great product.

I have a Bambu A1 Mini and I wanted to print out softer TPU protection for my DIY FPV Cinewhoop and this product worked great as bumper material.

Good

Really beautiful results.Easy to print. Just put it in and go. Same pla profile as normal.Printed onAnycubic cobra 3Prusa i3mk3sPrusa Mk4Ender 3

No drama printing on my Prusa, using a flex filament preset. It can be a little stringy, but nothing that ruins a print so far.

Very surprised how easy this prints. Will continue to keep buying

Polymaker is quickly becoming my goto filament brand. It's quality is superior to many other brands I have used so I decided to try their poly flex material and was beyond satisfied. This worked so incredibly well in my bambu x1c printer. The filament lays down smooth, and printing was a breeze..I highly recommend this filament if you need to print Tpu. We utilize ours in combat robotics, so it must be strong, be capable of correct sizing and overall high quality as it will be subjected to extreme stresses.

I have used this for multiple printed ant combat robots and it has held up great, no damage has ever been done to a part made from this. The one drawback is the fine tuning that is necessary to get a clean print, I haven't even figured it out yet. My models usually have so much stringing that I have to sit down for 30 minutes and clean it off using a heat gun and scissors. Other than that, it has worked well for many things other than combat robots too. It is probably best to use this in less precise applications at the start, while you figure out the settings.

Was a pain to feed into my Prusa Mk3 and I had to tweak the idler tension, but once I got it "right", the "amazon basics TPU" preset in PrusaSlicer is all I needed to set. Great adhesion to the textured sheet - first layer calibration has a lot of leeway since this stuff sticks so well.

This filament was a bit tricky as it required very slow printing speeds to get good results on my Bambu Lab X1C. That being said, after dialing in the settings just right, I was able to get great results.

First time use of TPU and I found this to be very easy to print. Using a Prusa MK3 I choose the FIllamentum Flexfill 92A profile and adjusted the temperature to 220 and saved it. I used the default 0.2 layer height settings and adjusted any speeds greater than 50 mm/s down to 50 mm/s (recommended max speed per the guide). Everything printed better than expected on the first print. I did have some stringing when I printed multiple small parts closer to each other that was easily cleaned off. I have not yet taken the time to tweak anything to minimize stringing. Over I am very pleased with the PolyFlex90. For that matter I have been happy with every filament I have used from Polymaker.

I found the filament to be a bit tricky to configure (~30 minutes of adjusting). Once I figured it out, the printing is going great. Most of the trouble was connecting the infill properly, as it was only one path wide.0) Turn off (or limit) retraction if possible! The filament got soft and bent around the feeder gear, with retraction on.1) The printing speed on the box (30-90mm/s) does not match the speed on the roll (30-40 mm/s). I'm printing very slow.. probably 30-40mm/s.2) With a triangle infill, Cura has it so there is a zig-zag pattern which produces the infill. The second zig-zags were tearing up the first, so I raised the extruder temp to 235C. Slowing down helped this too.3) Turn up the bed temp to 80C or so for the first layers to get good adhesion, this stuff cools fast and then shrinks
