Help with acrylic engraving (edge lit LED)

I’m using a atomstack A5 diode laser, i’m trying to engrave clear acrylic. i have used quite a few methods the best so far is spraying the acrylic with black paint. the issue i’m having is, i’m not getting the frosted look on the engravings so when i put the acrylic on the led base the engraving is not visible.
any idea what i could do to improve?

Generally, an led can’t directly engrave clear acrylic… that’s why you have to paint it. The paint burns off and that’s what damages the acrylic.

It probably not going deep enough to get the results you want. If you want to do this, you’ll need something more like a co2 that will actually directly effect the acrylic. Even my fiber can’t do acrylic as well…

This is an early one from my co2 machine, still kind of Mickey Mouse. I think this is what you are looking for. You can feel where the laser took out the material as it’s relatively deep… The spots are the protective cover I forgot to remove from the back side… :frowning:

Good luck…
