HELLO3D Glowing in The Dark Orange PLA Filament 1.75mm, Luminous PLA 3D Printer Filament, Dimensional Accuracy +/- 0.05mm, 1KG(2.2lbs)/Spool, Fit for Most 3D Printers, No Winding, Eco-Friendly

I love the shade of blue in this multicolor filament! It has a very nice blue and is a semi opaque filament when its not charged. The glow seems to be spread nicely in the filament and was very easy to print with.

The media could not be loaded.  First I want to start off by saying that any of the reviews saying that this luminous rainbow filament is anything other than perfect haven't taken the very little time it takes to do a temperature and retraction tower.I can honestly say that this filament exceeded my expectations by FAR. I've used "glow in the dark" filament from most of the big name brands, and this stuff is so much better.Was delivered in a vacuum sealed reusable package. It actually made a suction sound when I opened it for the first time. It was rolled very nicely on the spool without any overlaps or tangles. The spool itself is a very durable clear plastic. Much nicer than other brands I've used.The color shift is even and predictable and glows beautifully! During the day, it's a really nice white that's pleasing to look at. You would never know that it glows in multiple colors until the lights are turned off and it comes to life!I took several measurements of the diameter at multiple locations, and it was all well within the advertised specifications of +/- .05mm.Hello3D is the only company I could find online that offers this Luminous Rainbow color. I saw something close but this was exactly what I was looking for!I highly recommend this filament to anyone in the market. Look no further, this is your stuff!TLDR: Don't believe the reviews from people who don't necessarily understand that every filament is different and require different settings. Prints like butter, very high quality. Look no further... This is my new "Go-to" filament for luminous projects!

Not a fan of printing with glow in the darks as they can be more brittle and finicky than other filaments, but had a special request order for a gift. Have to say the color is bright and longer lasting than many other colors! No problems with printing with it. Would buy again if situation arises.

I bought this because it was the only yellow glow filament I could find a whole roll of on Amazon. It prints well enough but unfortunately the glow effect is very, very faint. Even leaving a print in direct sunlight for over an hour, the glow is barely visible in total darkness. (Incidentally, leaving any PLA prints in the sun warps them, so don't do that!)

The media could not be loaded.  Well after a few quick tests I went and did 2 of my largest tests to see how it looks... the Women’s body is 3 perimeters and 0% infill... the Benchy was 3 permiters and 10% infill, the cylinders were 4,5 perimiters and 0% infill... I’m currently doing what I think is the best setup of 3 perimeters but with 10,20,30% infill and I’ll compare...After some temp tests I also found that at 230-240 above the recommended temp the filament is amazingly clear but if you print it at it’s recommended temp of 210 you should get results like mine. I also ran them at 100,105, and 110% flow... I found that at 110% I got the best results and made sure the layer lines all overlapped themselves of else you would see transparent gaps.I’ll post up other prints down the line when I get them done. Initial thoughts are pretty damn amazing... it’s def a different type of look than regular GITD but it would def make some prints really look amazing

Works great in my 3 d printer

Printed good with some of our small pieces but did not adhear to our heated bed on a larger flat print . The glow aspect is almost non existent

I have waited to write this review cause I wanted to test and see if things changed as I used the roll. This is PLA filament how it is pretty low quality. it doesn't print very smooth and is prone to breaking. Oh and it doesn't glow as the post claims. If you put a black light on it, it will sort of reflect it but it is translucent (not entirely) so it really doesn't react to black light either. Pretty much a waste of money and I only use it as a test medium now to verify a print file and test fit.Not worth the money. Do Not Buy

Necesita parametros muy especificos para que funcione como un PLA comun, el brillo en la oscuridad si aparece, pero necesita cargarse demasiado en compracion a otros filamentos

Not sure if the issue is our printer or filament, but nothing is sticking - did make two items and since then nothing.

Buen material.

Product prints well. It is difficult to charge in order for it to glow in the dark. It needs direct light like a flashlight shining directly at it to create any charge.

Lo he tratado de imprimir desde 190 hasta 210° y el brillo no dura, el filamento es transparente y hay que dejarlo mucho tiempo al sol para que brille, pero el brillo es muy tenue y tiene que estar completamente obscuro para que se vea el brillo, ademas que dura muy poco
