Quoted from Sheprd:I looked into this at one point, and like you, struggled to find anyone that was using a small laser for our application. One thing that I did see is that it is difficult to cut clear plastic with a laser... energy wants to just pass through. Cutting opaque sheets is no issue. I hope you find a solution, because I also would like to do laser cutting. I'm sure it can be done (CPR cuts theirs with a laser), but how large of a laser is needed to cut clear PETG?
Just an off thought. I am in the sign business, but we don't cut with a laser. However, if you applied dark matt finish vinyl to the top of the plastic. Would the laser then heat up enough at that point to cut through the clear? Seems it could go either way, yes and great. Or no, just cut the vinyl and pass right through the clear.
