AMOLEN Silk PLA 3D Printer Filament, Shiny Multicolor Christmas Rainbow PLA Filament 1.75mm, Gradient Color Change PLA 3D Printing Filament for Most FDM 3D Printer, Red Blue Green Grey, 1kg (2.2lbs)

This is a four pack of PLA filament. GITD green & blue, marble, & color change.The GITD filament worked as expected. The Green takes any light, even a pocket flashlight worked. It was very easy to print with & even as a novice, I didn't have any issues printing with it. I did put the setting (Matter Hacker) on translucent though. Everything else was the same.The GITD blue (shown as breath) printed very well with the same settings as above. It needed some supports (don't they all?) & these came off pretty easily. I didn't need any real sanding to clean them off.The blue needs a little stronger light, for a longer time, but did very well when it got that (see pix).Both GITD glued easily with E-6000 clear. "Super" glue wasn't as successful, but I didn't think it would be.They look great with a black light as well. Shown is a small section vs the color changing filament.Color changing filament.This filament printed quite easily, & I didn't have any issues at all. It stuck to the glued bed (I make my own bed adhesive), & there weren't any issues.It looked great on the heated bed & while it was printing, even the spool had a color change. It has a nice translucent skirt, & the colors were a yellow as it printed. Once it was finished, it didn't change color. Could have been the heated bed, I don't know. I was in a rush to get the gift done for someone. I tried using a black light as well, but as you can see, it didn't do anything.The supports were a little difficult to remove, but cleaned up very easy, with my thumbnail & finally with a riffler.I haven't used the marble filament as yet, but will in the future. I'll update this, when I do. It's vacuum sealed & stored in a hard plastic container.Overall, these filaments from Amolen are fantastic! I had very little waste, & that was from supports & skirting.I would like to see more combos or kits like this from Amolen. I don't always need or want a big roll, or I may not be sure about the filament & a small roll will be enough.I'm confident that any filament from Amolen will work just fine, it just depends on how you think you may need it to work (like the color change above).If you're looking for some great, easy to print filament, that adheres very well, you will do good in using Amolen when you get the chance. I may switch up my supplier.

I was hesitant to buy this since the price tag was about 40% higher than most other tri color silk filaments from other brands. But Amolen is probably my new favorite brand for quality after having bought 4 rolls of different filament of theirs. I really love orange and blue complementary colors. Firstly you would be hard pressed to find a blue and orange filament. Secondly, it would probably look like a brownish/bronze color in blended areas. But this one uses a light teal and includes a coral to balance it out. I printed a print-in-place articulated sparrow. A complicated print. I needed to use glue stick for the tiny joints on the first layer but otherwise the filament adheres really well to a textured plate. I printed at 205/65 bed. I printed this slow at 60mm/s. Retraction at 2 @40mm/s. No supports aside from beak. The overhangs show ZERO blobbing or sagging. Considering the big overhangs under the wings, this is very very impressive. There was very minimum stringing, which might be resolved with higher retraction. This print is basically perfect. Maybe the most perfect print I've had.My only complaint. One side of this bird looks green (still better than a bronze/brown). I don't think this can be helped. The blue is more pronounced on the undersides. A lovely perwinkle blue silver. I don't know how to get the blue to be more visible and the green less visible but I'll tinker with it.I absolutely will be purchasing the teal and pink filament in the near future which also looks amazing. But this one really exceeded my expectations.

The media could not be loaded. I actually ordered set A, but I was sent B instead. There was some sort of goof up at Amazon because of low stock on A. I was not too bothered since I was interested in getting some GitD Blue filament, and the Tri Color Change Lava sounded interesting.First thing's first. You have to get your slicer settings right for these filaments. My attached photo shows temperature towers going from 220C to 180C, bottom to top. Left-to-right are the Tri Color, GitD Blue, GitD Green, and Marble. I had a lot of stringiness above 210C. The odd waves seen in the picture at higher temperatures are partly an artifact of Octoprint going back to the center for photos, so ignore that. The TriColor had some serious issues when it got too cold, but 200C seems to be right for my Prusa i3 MK2S. Also, I measured all the filament with calipers, and they seem to be 1.71mm. After changing this in PrusaSlicer, it looks like my prints are coming out much better.I like the fact that these come in smaller spools, especially for what I would consider novelty colors. I am not a frequent printer, so I don't go through large quantities.Regarding the GitD Blue, you need to manage your expectations. GitD Blue glows much dimmer than Green. I knew this ahead of time. Still, it is a pretty blue glow.Regarding the GitD Green, I suspect it is using zinc sulfide as the phosphorescent pigment. It makes a good green color. I have a GitD Green from another manufacturer that glows brighter and has a slight bluish tinge (probably strontium aluminate for the pigment). The difference could also be due to the amount of pigment present, but that is something I cannot measure. Anyhow, more GitD pigment also means that you might be ruining your brass nozzle quicker (there are a number of YouTube videos about this). I made a crystal print using this filament (time-lapse video attached) with a bright UV LED to keep it charged up, and it looks pretty cool. Print was clean.Marble ... I don't know how much of this I will use, but it printed fine. I was getting the set mostly for the other spools, but it is good to have this in my back pocket in case I want it. Like most "marble" filaments, it is more of a flecked/peppered look as opposed to swirly marble.The Tri Color Lava is pretty neat. The darkest it gets is a sooty charcoal. Watching the color gradient during a print is fun. I have made some geometric puzzles with this filament, and it is fun watching the colors change as it takes people a while to solve them. I suspect this is made using overlapping dark-to-light and orange-to-yellow pigments. It takes a fair bit of heat to get into the full orange range and even more to get to yellow. I am thinking this would be a great filament for electronics cases (especially for something like a Raspberry Pi 4) to watch for hot spots.Update:Added photo of what I suggested. I designed a RPi4 case (you can find it at prusaprinters model repository) and used the lava filament. Under load, the CPU was registering 64C. The transition to yellow was somewhere around 54C. You can clearly see the hot spots with this filament, which is pretty cool (hot?). This helped me design some better ventilation.

Really beautiful, smooth silk pla! Prints great on my A1 with generic silk settings. Definitely buying more!

This color prints great, other colors not so much
