https://stream.echo6.co/videos/watch/2a6274e0-d83c-44ca-a9a4-5b0b005f6166 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.
