Description
What is the recommended printing temperature for this filament? For optimal results, we recommend a nozzle temperature between 210°C to 230°C. The optimal bed temperature is 50°C to 60°C. However, we suggest starting with a temperature tower test to fine-tune the settings for your specific printer and environment What nozzle size is compatible with this filament? This filament works perfectly with standard nozzle sizes of 0.4mm. To address the issue of phosphor clogging the nozzle, we recommend using a 0.6mm nozzle size. What are the print speed recommendations? A good starting speed is 50-150 mm/s for general printing. For the initial layer, we recommend slowing down to 20-30 mm/s to ensure a perfect foundation. High-speed printers can often push beyond this with proper tuning. Is the diameter accurate? Yes. Our PLA glow-in-the-dark in the dark filament has a tight ±0.02mm tolerance for consistent, reliable feeding and print quality. Best uses for this filament? Perfect for creating glow-in-the-dark models! Ideal for Halloween/Christmas decorations, nightlights, toys, and creative projects with a magical luminous effect.

Set name: Firefly Green
As you can see in my video this Green Firefly glow in the dark PLA can print at __295°C__ without a problem (and without a fan blowing on it). Just amazing. The blue firefly is equally good and I've ordered it many times. In fact I played with them with my 3D printer pen and I was able to pull a molten filament as thin as a human hair and wrap it over and over around a pyramid I made of only these filaments. I felt like Spiderman or something. This stuff is on a completely different level than any PLA I've ever used and I don't just mean glow in the dark. I said "BUT" in my title. Why? Well despite this being my favorite glow filament (and i have purchased at least 100 different spools of glow filaments) with Firefly the glowing "firefly" particles can clog your nozzle AFTER you stop printing and let it sit hot so the crystals slowly sink in the liquid plastic inside the hot end and then coagulate at the tip like a clogged artery. If this happens because you had to pause the print for a while or something, usually just heating the nozzle up to 300°C will be the fix. But if the hot end cooled all the way down for hours or between prints, you might have to heat it up and use one of those needle tools to break it loose. The easiest fix in my opinion is to follow this very simple 3-step procedure when you're done printing or need to pause for more than a few minutes: 1) pause or end the print. 2) set the hot end down to about 60°C. 3) once you hit about 80C, reverse the extruder so you back the filament out of the tool head (basically a "cold pull" as it's called). That's all you need to do and it doesn't even take 1 minute. The 100% way is to just run 6 inches of non-firefly PLA filament through the hot end at 200C when you are done printing or need to pause for more then a few minutes. But my version of the "cold pull" has never left me with a clog that didn't burst open at 270°C and the other 19 times out of 20 it doesn't leave any clog at all. This might sound like a lot but it's very simple. And isn't it true the best things in life usually take a little extra work to properly enjoy? This is for SURE the MOST BRILLIANT glowing filament (PLA or any other kind) and that's a small price to pay. Unfortunately the price for Firefly is not small and there's no bulk ordering to get it cheaper. But once there is, I'll gladly by 4kg of blue and 4kg of green and actually any other color they do Firefly with. Oh and by the way, their Firefly style glow in the dark also happens to be the most beautiful and long lasting glow in the dark filament you can possibly buy. Do yourself a favor and buy a black light or UV lamp and you will have such a treat you'll wish you could comment on my review thanking me. Unfortunately you can't but at least you can click that this was useful because I would consider knowing the most physically remarkable and visually stunning glow filament to be very useful indeed!! UPDATE: I printed a plate full of stars and space stuff for my son's room. Since one of the stars was right in the center of the plate, i could run the print again without removing the various pieces. I ran it 3 times so the thickness was trippled. I then used some of that tacky glue you can get here on Amazon. It's the stuff for crafts that dries tacky so you can put things on walls and ceilings and in scrao books and move them around later. I put it on the pieces right on the plate (holographic plate for a little extra pop) and when it was dry i stuck them on the ceiling of his room and charged them up extra with my UV flashlight and his room light. Then at bedtime when u turned off the lights and he had blue and green stars, planets, satellites etc all over his ceiling, he was overjoyed. And the extra thickness to them means they glow for almost 20 minutes. And what did that memory cost me in materials? $2? If you try this technique please put a video of it in your review here and once somebody does that, I'll show mine. That way i know my effort typing all that out was worth it to somebody. 🙏

This is a great filament. But there are three things you have to understand before you start to print with glow in the dark filament. 1. You need a hardened nozzle for your printer. Glow in the dark filament in abrasive, and will wear away your nozzle. Once or twice for small projects won't affect it too much, but more frequent usage will.. 2. The Firefly Blue and the green Filament look great and glow in the dark, but you have to increase the infill to get it to be a brighter glow. More Surface area also helps as well. 3. This filament is UV reactive, so having a UV flashlight and shining that onto the filament will cause it to become extra bright. Even a cheap basic UV light works well to charge the filament. I used this filament to print crystals for a DnD campaign, stars and planets for my daughters ceiling and they have worked well. It is a speckled glow however,, not a full pure glow,, so just a heads up on that.. they Even glow a little just from her ceiling fan light charging them. Overall, I am happy with Amolen's filament. It is easy to print, and was easy to use, adhered to the bed very well at 55 C and the blue color is great. Its a good value for the money and had a few tangles. But I also bought used and returned so that is to be expected but it wasn't a big deal.

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.

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 v1.2 Flexible Magnetic Build Plate (Creality Official) BMG Clone Extruder Cura 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!

Very disappointing filament. I bought this specifically because it is advertised as “Glow in the Dark Purple,” but there was essentially zero glow-in-the-dark effect. Under a black/UV light, the filament reacts slightly while the light is shining on it, but once the light is removed, there is no meaningful afterglow at all. That is not what I would consider “glow in the dark.” The other big issue is the color and opacity. The filament is almost completely transparent, more like a lightly purple-tinted stained-glass effect than a solid purple filament. If you print it over or combine it with another color, you can clearly see the other color through it. If you specifically want a very translucent purple filament that reacts under UV light, maybe this will work for you. But if you are buying it because the listing says “Glow in the Dark Purple,” I would not recommend it. What I received did not perform anything like I expected from that description.

I'm using a Bambu X1C, and After my temperature towers looks pretty mangled, I was worried about this red glow PLA. But my ironing test was ridiculously good, and this test search I made is one of the cleanest I've ever created. Then I noticed cover for my tool head had fallen off, so that probably explains the mangled looking temp tower. The color is a lot lighter than I was hoping for, considering the reds in the product photos, which is the main reason I'm sharing these print pictures. It reminds me more of a red PETG than any red PLA I've used. Which explains why they don't show any regular lighting pictures on their product page. My phone's white balance is having a very confusing time, I'd say the swatch showing the transparency is the best representation of the actual color that comes out. Does it glow in the dark? Definitely. With my UV light the light reaction is even more pronounced than Elegoo's matte red, which pops really well under a UV light. I created a color test with a much darker red base of Elegoo's matte PLA and layered this on top to see how many layers I needed for how strong of a glow effect and if it doesn't detract from the main red base. The glow pop with the UV is almost blinding, even at just 0.2mm. however at 0.2mm without the UV, in regular color it already mutes the underlying stronger red, because this color is so milky in comparison. The glow in the dark at 0.2mm was ok, but as expected it got progressively stronger and brighter the thicker the layers. I've seen other filimaents in other colors glow a lot more at a lot less material thickness, but it's still very pronounced in the dark and should still look great on actual regular prints. I'm guessing since red is pretty rare for glow in the dark stuff, companies can only do so much with this kind of chemistry.

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've been on a quixotic quest to find 'The Perfect Orange' filament. I'd gotten so desperate that I didn't care if it was PLA or PETG or some ratty shoestring from the closet floor. Dozens of spools that looked amazingly orange in the bag...turned into some sickly pastel, amber yellow, fluorescent/hi-viz, or 'BaskinRobbins pink'-colored abomination on the build plate. This Amolen 'Pumpkin/Carrot Orange' PLA filament, however, is the the most perfect, honest, no-nonsense orange I've ever found. Its color holds true throughout from spool to finished piece. And my Bambu A1 loves it: it prints smoothly, is silky-shiny and feels wonderful to the touch. There's almost no post-processing work beyond pulling off the supports, and those come off very cleanly. I print mostly gaming minis, knife scales, jewelry and other small, detailed work. So far, with my .4mm nozzle, settings on 'Generic PLA', I'm getting phenomenal results! I'm going to try my .2mm nozzle and the 'Minis' setting on my slicer to see if the quality holds up. I'll update this post, once I have data.
