Here’s the “final” version done with Inventables two color blue on white 1/16 inch acrylic.
Here’s what it looked like before any cleanup. I opted to peal back the plactic film they ship it with, because engraving looks terrible if you don’t. Most of the mess just wiped away with a cloth, although I think I should have rinsed it first because wiping it left some blue streaks in the white areas.
This is what it looked like after wiping it with a cloth, then rinsing and rubbing a little with the cloth.
I ended up using a little 70% Isopropyl Rubbing Alcohol poured into the cloth and then using that to rub out the blue streaks in the white. It worked well and took only a minute or two total.
The settings are used were the ones @pdobrien said he used for his One Ring Escutcheon the gold on black Acrylic. Although, I did try increasing the cut power to 75, but it still didn’t quite cut all the way through. It was still easy to “pop out”.
I’m pretty happy with the result, however I’d like to get a higher quality (more details, better resolution) artwork for a future revision.
