Having been inspired by the coasters on thingiverse designed by Timberwolf0810 I decided to try flowing resin into the recessed pattern in one. I thought the pattern might be a bit detailed, and was concerned that two-part resin might start gelling before it had all been encouraged into the detailed areas, so I measured one of his coasters and redesigned it to match with some chunky recesses in a shape with dams designed for controlled resin flow and multiple batches.
Then I thought about my small bottle of UV cured resin and thought it might give more time for getting the resin into details before choosing to cure it with light. I went on eBay and found some bigger bottles of UV cured resin intended for casting small objects.
To see how it would work I mixed in some eBay glow in the dark Strontium Aluminate powder from China and instead of using the little UV flashlight/torch that came with the resin I chose to use another eBay gadget, a USB rechargeable UV nail varnish activator. It works well and has a built in timer.
The result is pretty good. It does help to chase the resin around with a low power hot air gun, but that isn't essential as it has as much time as you want to flow into every crevice. The hot air did help bring bubbles up to the surface and pop them.
Note that it does cure on the exposed surface first. Putting it in sunshine or daylight to finish curing inside may be a good idea.

Here's the script for making one of these coasters in openscad.
//RESIN-FILL COASTER
$fn=100;
difference(){
union(){
//bottom plate
translate([0, 0, -1])
cylinder(h=3,d1=94,d2=100);
//raised lip section.
translate([0, 0, 2])
cylinder(h=3,d1=100,d2=100);
}
//Inner core.
translate([0,0,2])
cylinder(h=4,d1=94,d2=100);
//recessed patterns
//central disk
translate([0,0,0])
cylinder(h=3,d1=15,d2=15);
//six sub disks and radials
for (i=[0:60:300])rotate([0, 0, i]){
translate([-30,0,0])
cylinder(h=3, d1=15, d2=15);
translate([-21,-2,0])
cube([20,4,3]);
}
}

You do have to pour in layers. Sometimes, doing an additional cure upside down (with clear silicone molds) can help get the light to all areas/layers.
Acetone cant damage pla. Acetone has no affect on pla. On abs acetone has effect.
I also tried something with print and glow in dark powder and resin.
Hi Clive you should do more projects with uv resin
The way I dealt with the stickiness was to leave it in warm soapy (dish soapy water).
Question. Do you know how long the glow lasts when charged? how long should you charge it? And id the "glow" duration relative to the qty of powder in the mix? thanks clive. love the vids 👌
Looks like a push nut !
I recommend an old beer mat ,works a treat ! 😂
Beautiful
I hope that’s not strontium 90 from the local power plant that they’re getting rid of on eBay…
I love these "Clive plays with Glow in the Dark" videos because I'm the terrain maker for our Warhammer group (mostly due to owning 3d printers) and these give me all sorts of ideas. (The current idea is some of this glowing UV resin in a processed Resin printed model for glowing detail)
Best way to charge this kind of objects is using photography flash, instant and very long lasting effect, try it.
I ordered this raisin and it just came from China. I have to say I am impressed!
It cured almost instantly in the mid day light here in Northern Greece! Literally in seconds!
It cures so fast that i managed to repair my vacuum cleaner using additive 'manufacturing' technique… put some glue, expose to sun, some more glue etc.
Very very interesting! But expensive. Any cheaper alternative?
This is epic!
I remember as a child using some glow in the dark face paint at a Christmas theatre showing of Charlie and the chocolate factory… happy days.
Probably really bad for you but i'm still here.
there are better UV resin that isn't sticky. UV resin shouldnt be sticky after curing. just a lil tip. ty for your video
Will this UV light kill germs? Sorry youtube suggested this video after today's upload lol
Isn't there UV Resin that cures at different wavelength?
wow the gitd resin is truly magical in this….MAKE ALL THE THINGS GLOW <3
