AMOLENTPU 3D Printer Filament, Transparent Multicolor Rainbow TPU 1.75mm, Color Change Flexible Soft TPU 3D Printing Filament Supports High Speed, 1kg Spool(2.2lbs), Blue Green Orange

Although all TPU filament likes to absorb moisture from the air, this Red, Glow-In-The-Dark filament from Amolen printed beautifully right out of its vacuum packed bag. My experience was the same with Amolen's green and yellow GID TPU filament. To keep these from absorbing moisture, I rotate the spools, keeping the other two spools in my filament dryer. As a result, my 3D printer is delivering beautiful results every time. The material charges up nicely with any UV flashlight, and it keeps glowing for a long time. Although these Red, Yellow, and Green Glow-In-The-Dark filaments are more than enough for my projects, I know I'll probably break down and buy Amolen's Blue GID TPU.

Awesome filament. Looks amazing and prints well. Was successful in printing our sweet new crocs (colors in the photo are a bit darker than they really are, so the colors appear to be just as advertised)! No complaints, comes off the spool nicely with no tangling. Follow the instructions of your prints and machines, and it should do well for you too.

It can be a bit tricky to print. I had to use the very high end of the nozzle and bed temp on the label. But it prints. The glow effect is way better than I expected. Many glow filaments don’t glow a whole lot, and those that say they sparkle don’t sparkle that much. This one does. Looks every bit as good as the product photo. It’s also a good price for what you get. I’d buy it again.

Does need to be printed at higher temperatures than normal PLA I had to change settings to make it print clean.Looks cool

These bags are working well with the battery vacuum I purchased separately. I’ve had a couple that leaked, but the majority are sealing up very well and holding strong. Overall, a good value and they do the job as expected.

I had bought this filament while half-disregarding the reviews, which was a horrible mistake. First red flag should have been that the bag the filament itself wasn't fully vacuum tight. First couple of test prints came out just fine, so I thought nothing of it and continued with the project I was working on for my nephew's birthday.Third print comes out weird so I try it again and watch through the whole 15 minute print. The first layer had massive over-extrusion issues, leaving globs of plastic everywhere. I go back and check my slicer settings, no change, tried a different filament with the same file, no issues. I go "this sucks but im on a time limit and i cant get another spool before the deadline" and carry on just much more carefully.Then, the filament stopped adhering to the build plate. I have a textured PEI sheet and i haven't had adhesion issues in a long time. I relevel my bed, realign the Z motors, clean the bed with rubbing alcohol, no change. I had to use glue stick AND painters tape to get these prints to stick finally.So I finally get most of the prints done and I have a few days before the deadline so I start doing final assembly. The screws glide through the captive nuts and het the slightest resistance from the plastic, shearing off the entire screwpost and ruining an 11 hour print. Print it again, higher screw tolerance, screw posts shear off. I tried using a soldering iron to melt some similar color donor filament into place and hold everything together. As soon as my soldering iron touched this filament, I got the instantly recognizable reek of ABS.I'm writing this review on the day of the deadline and my nephew is crying about how he didn't get a birthday present from me. This filament has no layer adhesion, will shift between absolutely glued to your buildplate and more slippery than ninjaflex without warning, and will leave globs of loose filament inside of your infill. I have less than 200g of this left and I won't even use it as a purge filament.

The print and adhesion quality is alright, but the glowing is not anywhere near what you see in the product images. I don't know what light source they're using, but my UV lights do not cause the glowing to work.
