Removing Spray Paint with C02 laser
My ultimate goal is to create a resist mask for electroplating a watch dial. I was thinking that I could spray paint a brass disc and use a laser to burn off the paint selectively to reveal my pattern which I would then electroplate, and then use acetone to remove the paint to reveal my actual design. I am not looking to mark/engrave the brass, just remove the paint.
I posted the picture of what I am leaning towards.
It would be a 28.5mm diameter disc which essentially makes my project tiny details. Would the entry level C02 lasers you see on Amazon for $150ish work for my project? Would they give me good enough resolution?
If not, what should I look for?

Suck it and see. Probably not but for sure you will learn plenty. I have an expensive 1024nm engraving laser. I tried the sort of thing you are talking about but attempted to make printed circuit boards. It worked but was not worth the bother. You have to also consider the stuff generated when you burn the paint. Kills filters fast..
Re: Removing Spray Paint with C02 laser
I originally got my idea from the PCB making community. I have done toner transfer and get good results its just that the good results are inconsistent. Since this is a watch dial, when put under the glass any errors are magnified a bit. When you say it worked but wasn't worth the bother, can you explain a bit more?Originally Posted by stjohn4
Luckily, I'd be doing this in my shed with door open and fan blowing out so vapors wouldn't be an issue.
