iSANMATE PLA 3D Printer Filament, PLA Filament 1.75mm Bundle Dual Color Filament Silk PLA, Dimensional Accuracy +/- 0.03 mm, 250g x 4 Pack

These glow in the dark filaments are great! They just need a little light and they glow a long time. The only thing is if you want all the rainbow colors on a print, it needs to be fairly large. Otherwise, you willnonky get 2 colors. Quality is good. No issues with printing.

Review is for the: "iSANMATE 3D Printer Filament, PLA Filament Glow in The Dark, 1.75mm Dimensional Accuracy +/- 0.03 mm, 1 kg Spool" As with most any filament from the factory... it works best when dried for 10+ hours. Many people report how brittle this filament is & yes, wet filament is brittle. So, dry it first. Then it will work well. I have had great prints with the Glow filament. After charging off a Bright light for 20 minutes, it will last for a few hours. Thicker prints works best of course, as there is more product to glow. Good detail can be printed with this. Important to have the settings correct, as the Glow is actually a PLA+ which melts at a higher temp than PLA. Appears to be a bit stronger than PLA, but not like a CF or PETG. I would purchase again. Be sure to dry it first.

The color is vibrant, consistent, and looks amazing on finished prints—exactly what I was hoping for. It has a smooth, rich tone that really pops, whether I'm printing small models or larger pieces. Print quality has been excellent. The filament feeds perfectly with no jams, and layer adhesion is solid. I’ve had zero issues with warping or stringing, and the surface finish is clean and professional-looking every time. It’s clear this is a high-quality filament, and it’s become my go-to for any projects that need a bright, eye-catching pink. Highly recommend for anyone who wants great results and reliable performance!

I was excited to find some nice strong glow in the dark PETG! I had some little water resistant keychain containers I wanted to print and I thought a glow in the dark lid would "brighten" them up. The colors print beautifully on my Bambu P1S (I might have had to raise the temp 5C ) and printed smoothly. I noticed no brittleness, stringing, and used a 04mm hardened steel nozzle - so no clogging. Note, I keep my plates well scrubbed with Dawn and wipe with IPA before each use. I also store my filaments in cereal boxes with plenty of fresh desiccant and keep them below 20% moisture. The reason I took off a a star was the purple did not glow. I got the 4 color sample pack and maybe I got a bad batch but I did read one other person had trouble with the strength of the purple glow. Mine did not glow at all. Now it is STILL a beautiful color and I am thinking of ordering another roll (I am a purple addict). Forgot to take a picture of them. Next time I print all 4, I will add a photo to the review.

My first batch of this filament was good. Read my original review below. Not sure what happened, but this current batch is absolutely terrible. The first batch at least looked like it matched the colors. This batch, even though they were all different colors, all looked green. Not a problem, just annoying. The real problem is that it is so brittle! It snaps mid print, and even to the point it became extremely hard to unload as it kept snapping. Lastly it appears to glow less bright and for less time. Really not a good experience at all. I definitely won't be back for more. Sad. I'm new to 3D printing, but I have been a quick study and I'm starting to get some really cool stuff coming out of my Creality Ender 3 V2 Neo. I bought this glow in the dark medium to get some Halloween decorations ready for myself and my friends. The filament loaded into the printer fine and I never had a problem with it not sticking to the base or getting caught in the feeder. The haunted stump took 12 hours to print and it never had an issue. When it came time to unload it to put my normal filament in, it came out without a hitch all in all I'm very happy with the product. I just wish that they sold the colors individually as running such a big print ate through my green spool pretty quickly! ;). PS - It's been two week since I printed this and it still glows super bright in the dark.

I was fighting with my self on if I should knock a star off. It works fine. Looks very similar to sunlu glow in the dark blue but doesn't glow near as bright. I ordered this one because it could ship next day and sunlu was going to be a few days. I guess I wish I had waited. Now I feel like I am shorting my customers giving them a less bright glowing dragon. The one on the right is iSanmate in both photos. Used a UV flashlight to make them both glow.

Mixed review. Plenty of filament for the price and the variation in colors is awesome. Shipping was no problem and everything was packaged perfectly. Printing quality with this varies greatly depending on what your printing. It seems the melting point of the filament is definitely higher and our printer struggles a lot (using ToyBox Plus). Our temp is set to 210C and this filament cools very fast, almost faster than the printer can print it out and tends to clump up or not ahere properly to each layer making long filament strings all over the print. It seems to work fine with smaller and more compact prints like figures and sculptures but anything that requires the printer to print multiple areas such as legs on figures or longer items such as hexagonal patterns it can become a big mess. Would not recommend for smaller scale/introductory print machines such as ToyBox or lower heat units.

Great quality filament for the price. No adhesion issues. Filament works great.
