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

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.

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.

This filament glows like it was forged in a radioactive wizard’s lair. Prints smoother than butter on a hot pancake, with zero clogs, tangles, or sad spaghetti disasters. The glow is so intense that I half expect my prints to develop superpowers. Left a test print in my room at night and nearly had a heart attack when I saw a glowing ghost-octopus staring at me. 10/10, would mildly frighten myself again.

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.

Amolen filaments offer outstanding quality and a great selection, comparable to top-tier brands. The spools work seamlessly in the Bambu AMS without needing printed rings, and they print flawlessly using both generic and Bambu profiles. The consistency and reliability make this a go-to filament for high-quality prints. Highly recommend!

DO NOT BUY.Edit: despite what I said below, I tried the new bright rainbow glow filament. It’s beautiful and glows super well…except what I said below still stands. I have spent the past 24 hours having to repeatedly take my printer apart to dig out broken filament pieces, and with 45 minutes left in a 16 hour print, it finally failed completely, which means I wasted over half of the roll of filament (not great at $30 a roll). I’m also having to buy new Bambu nozzles bc the filament wrecked 2 during this attempted print, so I’ve wasted around $40 plus many, many hours of my time on this. Not happy.I love almost everything Amolen does. The vast majority of their filaments and colors are excellent, and I have zero problems with them. These glow in the dark ones are trash though. I have had to take my Bambu X1C apart and extract broken bits of this filament from various parts of the machine TWICE now in 2 days. I managed one print (but still had to dissect my machine after), then the second print failed, and required an even greater dissection to get all the little bits out of everywhere. I will not be using anything from this line again, I don’t want it wrecking my machine.
