UV resin can add a splash of color to projects. I'll show how to cut a wood nametag with a magnetic back and basic UV resin work. It's an example of how to add colorful UV resin accent to any engraving project.
I used the rounded rectangle and sized it for the name tag. It was placed in a layer to be cut last. The large lettering that will get UV resin was cut in the middle layer. The 2-pass engraving of everything else in the top layer. I had previously tried just deeply engraving the letters for the UV resin but the dark bottom left by engraving really diminished the brightness of the resin. The lion was AI generated and I removed the background in XCS. The solid maple was from the Hardwood Edge store at Amazon.
I'm using UV resin rather than epoxy resin. For a small project, it is fast and easy to use. I used standard low viscosity clear resin from Let's Resin and coloring dye from Sig-WongUS (both from Amazon). I squirted about a tablespoon of resin into the paper cup and stirred in 3 drops of blue and 2 of white dye. I found adding the white made the color show up much more. (Note: I forgot to take a small amount of clear resin and place a thin coat around the lettering then hardening it before continuing - it would have prevented the faint blue stain you can see in the final result). Put the tag on some backing - cardboard, paper, or tape - to prevent the resin from falling out and fill up the cut out letters mounding it a little. You can use a UV light but I use sunlight. I gave it 4-5 minutes then flipped it and did another 2-3 on the back (if you apply clear acrylic first, 2 minutes is enough for the thin coat before going back and adding the blue resin). The resin is now hard. Sand the mounded resin flush trying to avoid the engraved areas as much as possible. I took it down quickly with 80 grit on the belt sander then a little 240 grit by hand. It will look like your engraving is turning white. Don't worry, this is saw dust. Clean it out with a papertowel and mineral spirits. UV resin will break down with a lot more UV exposure and I want the tag usable outside so I chose a UV-protecting spray finish. In this case, Rustoleum Varathane spray (water soluble spar varnish from Amazon). Attach the magnet on the back with it's adhesive (or use something like Gorilla glue) and you're done.
