Got the 10.6 μm wavelength laser finally dialed in specific for this (weird) pmma material. Either that stuff is as hard as crystal, or we simply need a new laser. The stuff is so hard the feed rates to cut it needs to be turtle speed. 12mm/minute + air assit + new focus lens. For sure we're not dealing with regular plastics here :/

The etching turns out frosty - s-t-u-n-n-i-n-g. Very happy. Unfortunately this shot got snapped using my mobby... looks a tad better in real life. LED light is completely lost inside and the material is clearer than glass (92%). Pretty cool 'chemicals' I have to say.

Chopped some scrap/sample material so I have a template to work with when fitting the LED module. I just don't want to scrap a full window size piece of pmma atm. Hopefully this coming weekend I'll be able to etch my boxster's window (my flower lol).
