For a silk the stuff is great. I have done some 10hr prints with this and did not have any issues with heat creep. Prints more like a regular PLA and the color shift is really attractive. has some layer strength issues. but adding extra walls will compensate for that.

It's a great filament. I've only ever used Amolen filament. The color transition is amazing. It looks like a different color depending on the angle. Love this stuff. Worth the $. Especially if u only have a single color printer. Gives depth to a print without having to change out filaments. Runs great off a ams too. Just buy it already. (I suggest drying it out with a dryer, it does hold a bit more moisture, than basic pla.)

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.

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.

The filament overall is great quality, little to no issues when using. I received a badly wound 2 color roll and should have refunded it, as the layers are very noticable as it alternates on the layers. It is easy to tell if the roll is wound properly as one side of the roll will be one color and if you flip it it will be the other color.

I've been running a 3D printer for about eight years, and I've gone through at least 300 1kg spools, mostly PLA. My current printer is a Prusa MK4. I bought a spool of this filament for a project, and it printed everything great. I still had more pieces for the same project, so I bought two more spools. Almost immediately, the second spool *of the exact same filament* failed. Every print jammed after the first 2-3 layers, leading to nasty nozzle clogs that required multiple cold pulls to remedy each time. See photo #1 for a typical example. Since the results were baffling, I tried reprinting the same model with my tried-and-true Hatchbox PLA. No problem - printed perfectly on the first attempt. See photo #2 for an example of the same model printed with Hachbox PLA. I reloaded the AMOLEN filament and tried again - again, failure with a bad nozzle clog after the first few layers. Again, I used Hatchbox PLA to clear the clog and printed a model - again, printed perfectly, zero issues. I thought that the second spool of AMOLEN might have had some weird issue, so I loaded the third one... and got the same result. I'm mystified as to why I'm having such vastly different experiences with different spools of the same filament, printing the same models under the same conditions, separated by a span of only a few days. It couldn't possibly be moisture - the second and third spools failed less than 24 hours after being removed from their packages. And my printer certainly isn't the issue, since it still prints perfectly fine with other brands of filament. I'm going to submit for a reimbursement of both spools and will reorder an additional spool from another vendor. Very disappointing.

This filament has worked with both rolls i have bought on my Bambu X1C. It is a beautiful color and well liked.

This filament definitely has a higher cost than other silk single or multi color-changing PLA, but we have found the increased cost to be justified by fantastic value and quality. The attention to detail we have appreciated: including a resealable storage bag, proper winding of the spools for problem free feeding, plastic spool (controversial, but we prefer it), accurate diameter for amazing outer surfaces, and overall nice packaging. This isn't a full review. We just wanted to point out some interesting things about the dual sided filament. Unlike filament that changes colors either gradually or rapidly, the two colors remain the same throughout the entire roll. The gradient effects seem to be based on the direction of travel of the nozzle. The samples in the photo and video were printed on the FLSun V400 delta style printer, but that shouldn't really matter in this case. One thing we've learned is to rotate your print in your slicer to orient your gradient where you want it. There is a center line where the majority color begins to transition to the other color, so you can get creative with orientation for very interesting gradients. If you noticed poor overhang on the bottom of the oinkarinas, that was due to printing too fast, as well as one of the two cooling fans was inoperable. We will be using AMOLEN for decorative/visual prints in the future if these qualities are consistent.

Pretty good stuff

Good filament, prints good, watch temps when printing.
