« on: January 09, 2017, 09:20:43 AM »
I seen on youtube how someone could lqser engrave plexiglass with their desktop chinese laser if they painted the plexiglass black. My question is does this work? And if so would inuse a water based paint....or any other suggestions would be great.

It should work, just a few days ago I showed an example of etching glass by painting it black.
I have not tried it on plexiglass, but if you do let us know how it works out.

I was using glass so I used acetone. You will need to find a water based paint to get it off the plastic.

What I was saying was that the concept works using black paint to etch, but I only did it on glass which is a whole different beast for getting the paint off.

I don't think anyone in this group has tried paint on plastic - so just try it out yourself - its OK to have failures, I know because I have many, but I keep trying until I find something that works.

What if we paint a glass black and we put it under the plexiglass could be nice to try out

Again we are into an area that no one has tried things. All I can suggest is to try things to see what will work and what won't - then let us all know. There is a little cost in material but so much knowledge can be gained by just trying out an idea. Don't wait for others - try it your self.

With the glass I had at least 10 failures before I thought about and tried the black paint. I can think of at least 12 more possible ways that "might work".

The one that I plan to try today is BLUE tape painted black on GLASS, might work might not. Yesterday I tried BLUE tape on glass that was sprayed with water and would say it worked fair but I was not really happy with the results.
