I have seen laser etching into acrylic and that works but has limits as well.

What are you using the acrylic for?
Is there another plastic that will do the job and be easier to work?
Is the possible production level high enough to offset the cost of the laser and the cooling equipment needed?
If you are looking for finished edges, is milling the item then having it flame polished by an out source or buying a unit to do that reasonable to cost?

Those are just some questions that came to mind about where you are in this project and things that you might want to look into.

Thanks for the info on water jetting Michael! Thats out then :)

Didnt know or think there might be a the light transmission problem, never worked with plastics before this project so its a learning curve!

Production levels are unknown at this stage but we are exploring our options to try and figure out (guess) how many units we could produce on a daily/weekly basis!

We have tested flame polishing the milled edges but could not get a satisfactory finish (or even come close) using a butane blowlamp. lol
