Yes, it’s possible to laser those blown egg shells.
I’m still working out the optimum settings for it, and there are a couple of tricks to get a clean egg, but I’ll get there eventually.
I’m gonna have to set it aside for a bit starting tomorrow, but I thought y’all might want to see the progress before I have to go play accountant and do other assorted family related things.
(Man, I hate tax time…)
DO NOT look at the flame when you are lasering an eggshell. I actually watch the reflection in the dull metal at the back of the unit. And it’s still too bright.
Like I said, I’m still working on the settings - if you have it set wrong, you will burn the inside of the egg - leaving unattractive black spots on the backside. (Which you can see through the cutouts.)
If you set the burn too lightly, no black spots, but the material isn’t removed. While that can be scratched out with a needle, it’s super easy to break the egg, depending on the design.
(The planters are actually repurposed logo fails.)
I need to mess some more with the focal distance as well, to determine the optimal settings - these were just “take a shot at it and see what happens”, and I didn’t bother measuring. (That will have to be done eventually, but I’m still figuring things out, and I’m out of eggs.)
