AMOLEN TPU 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

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.

First time ever using any brand of TPU filament. Printed some antique mason jar gaskets (not for canning use) on a Creality Ender 3 Pro with a stock 0.4mm nozzle and bowden-tube type extruder. Following advice I read in a print forum, I printed just one object at a time to reduce stringing. The gaskets printed flat on the plate with no supports, using the settings shown in the picture (Prusa slicer). Worked perfectly on the very first try... Adhered perfectly to the stock magnetic plate and no stringing.Very pleased with this filament. Its very flexible and stretches easily. Not as much as a rubber band. It's more firm. And has more a feel like a flexible vinyl in terms of its surface traction. I plan to try printing some electric model car tires and tank treads to see how they work. May not be soft enough to provide good traction, but it certainly looks great. Very smooth printing so far.

So not going to lie, I’m only about 4 months into 3D printing so in no way am I a professional, and if the information I am about to impart on you is a “no brainer”, I sincerely apologize, but this could have saved me weeks of frustration. As stated, I am new to 3D printing. I have been using Hatchbox PLA exclusively in my Creality Ender 3 Pro with Glass bed (which I highly recommend) and for the most part, having little to no trouble at all. Then I bought a 1KG spool of the AMOLEN PLA Printer Filament, Multicolor Silk Metal Rainbow. Right off the bat, it felt “different” than the Hatchbox, stickier and more pliable. Load it up and try a quick sample string test print and it will not adhere to the bed. Just keeps getting all jammed up and stuck on the hot end. OK, no worries, I will just clean off the hot end and wipe down the bed with some alcohol and try again. Nope. Same thing. Check the bed level – it’s good. Swap back in the Hatchbox, prints like a champ. Put back in the AMOLLEN, no go. This goes on for a few weeks of putting the AMOLLEN back in, trying to get it to print, getting aggravated and putting back the Hatchbox. So, all the time I’ve been using Cura 4.6.1 as my slicer and have not adjusted a thing in the settings. Just for kicks, I decide to up the hot end temperature from 200° C to 220° C and lower the bet temperature to 50° C and BAM! It’s now printing with the AMOLLEN filament like a champ! No other adjustments necessary. Prints are coming out smooth and flawless. Again, I’m sure that this info is nothing new to a seasoned 3D printing vet, but to me it was going from throwing out the spool because I could not stand to look at it to what can I print now with this awesome multicolored filament. Buy it, with a little tweaking you will love it.

Before we get started let's just get my setup out of the way so you know where I'm coming from.Ender 3 (not pro)SKR Mini E3 v1.2Flexible Magnetic Build Plate (Creality Official)BMG Clone ExtruderCura Slicer with CHEP 4.7.X(Good) 0.2mm Profile.Alright so let's get into the meat of this review.When it comes to my printer I always wanted to try glow in the dark filament but was always worried that it wouldn't look good. Plain and simple, I'm glad I was wrong. Main thing to say is the glow works MUCH better when exposed to sunlight. I think it's the UV rays that is causing it to soak up so much energy so one day I want to try this with a black light.Temperature: I couldn't find a "best" temperature for it, everything from 180-210 or so seemed to look great which is a good thing. Means you don't have to worry about things looking weird and don't really just have to look for anything when it comes to the temperature. Just set it to 200c for the nozzle and 60c for the bed and you're good to go.Color: If you think you're getting a blue filament that glows blue don't. It's white under normal light but you get it in the dark and it glows a mighty blue. Just look at the pictures I posted. There are no filters. Just left them out in the sun for a few minutes, took them in a completely dark room, and took a picture. I really didn't expect the glow to be so bright honestly. It was a very pleasant surprise. I need to find some outdoor applications to use this in so that dusk looks even cooler outside my house. The white itself looks good and is even a little transparent. It could make a good surprise if you were to give a gift to someone who likes blue and they think you gave them a white item only for it to glow blue in the future.Adhesion: I'm starting to think the cheap filament I had before was what was causing them not to adhere to my bed but the 3 most recent filament's I have gotten have stuck well, though it may also be the new springs I got too. Layers stuck well to each other as well as to the bed. No layer shifting from anything and it didn't pop off mid print to ruin everything. No complaints when it comes to this category.Packaging: Came in a normal box with the flip open tab for easy storage as well as a sealed metallic zipper bag. Filled it with air and gave it a press to see if any air was leaking out and it wasn't so I went ahead and placed a few extra desiccant packs in there because I want to make sure this filament stays good till I use it all. I like the spindle itself. I don't know if AMOLEN's other filament's come on clear spindles as well or if this is it because the filament is a little translucent.Overall: I have 0 complaints and just can't stop raving about this. I'm hoping one day they have a glow in the dark purple and once they do I'm buying immediately. Next I hope I can get my hands on the shiny glow green (looks like it has chunks of EXTRA glowy pieces in it) and the color change ones one day. Cheers!
