Glow in the dark fillament recommendations

[Kurt Gluck]

Ok, I was resisting this, but granddaughters have moved to an actual bunk bed (not the one I printed :-) ). So… there is a request for stars and other items for the ceiling of the lower bunk.   Looking for recommendations for glow in the dark filament.   Radium need not apply :-).  

So:

Manufacturer/Filament/Printing-hints/any idea how long it glows :-)

I have loved Sunlu’s white glow green. Here it is in a green lantern ring.  I haven’t timed the glow but it’s reactive enough so once it’s charged in daylight, you can see it glowing even in a little shadow. 

I’ve also tried a white glow blue by hp3df and while it glows a nice blue, it is not as reactive as the green. 

I suggest getting a black light flashlight to help supercharge them quickly.

When you say - How long it glows - do you mean, on a single "charge"? Or, after it's printed - how long over time before it no longer glows after being charged?

I have my sculpture - which I printed the parts back in like early 2023 - and it still glows:

Filament is Inland(MicroCenter) ABS Glow in the Dark.

K-1, Michael 

I mean how long will it glow on the bottom of the top bunk in a bunk bed that has a tent over it without exposing it to a special UV light source :-) 

Thanks!

So far it’s been 20 minutes after the light has been on all day and the benchy is still glowing.

Yo there Mr. Doppelgänger,

Seems you're really Backing Yourself into a Corner - with what you want to do! Typically - you want the Glow pieces to absorb light by day - then they get to give off the light at night. But, seems - under the bottom of a top bunk - with a tent like structure around the bed - your making it so that the pieces really won't get hardly any light on them. 

When I was a young dude - a long time ago - during the early Stone Age - I had the idea I want to simulate an outdoor scenery of stars. Cause, I had gotten this tube of stuff - that you squirt out - and it dries - and it Glows. So - I made a bunch of dots on my bedroom ceiling - I even did like a Big dipper on the ceiling as well. But, in my case - it would easily get natural light by day - then it glowed nicely at night...

Do they have a night light or reading light by their bed in the lower bunk? For my kids with glow in the dark stars, the reading light activated them and they glowed for a while as they went to sleep.

They are 4.75 years old.   One of them has started to make requests.  For example, just as I was finishing the 1/3 scale bunk bed she told me that the dolls didnt have a dresser.  Then after the dresser was delivered she told me that Barbie also needed a bunk bed (printing now).       

When I get back from my RV trip west I will probably order some glow fillament.

Another question: I have been printing with the same hardened (not high flow) nozzles for over a year and a half (These are my 0.4’s I put on the XL at about my 6 month mark).  How do you tell when they are worn out?   Dont tell me it’s when your prints look bad, since if you’ve seen my prints, that would have been when they were new :-).

OMG - Mr. Doppelgänger - you're Funny as Hell - with your comment of " Dont tell me it’s when your prints look bad, since if you’ve seen my prints, that would have been when they were new :-)."

I wish I had a better answer for you. Honestly - if you have a Hardened Steel Nozzle - there is NOTHING TO Worry about for you - if you have NOT been printing Composite filaments - Glass or Carbon Fiber, or even Glowing Stuff(that's the Technical term). So - if you're only printing PLA & PETG - your nozzle should be JUST FINE - and NOT have Degradation - as those filaments will NOT degrade your nozzle. And, I suspect - if you print with ONLY those 2 materials - or even some TPU - you do NOT need to worry- and your single nozzle should in theory work FINE for a LONG Time - maybe several years - with no problems!!!

I sure HOPE that puts your Fears to Rest - at least for a little while...
