Not sure how other lasers will perform, however, here are some samples from mine. I use plexi with the protective film on both sides.... cutting is crystal clear with no "whiteing".
A set square I tried a while back after being inspired by DT's on the other site,
initially the markigs were clear, however, a log got lost when "glueing" the two halves together... engraved/etched on the inside...
Bench dog bushings... they are 25mm OD and 20mm ID, values engraved were the dimensions used by the laser to cut... allowance for the laser kerf.
5th. Pig puzzle measuring 75mm x 53mm x 2 layers of acrylic mm,
Pandora's Box puzzle, 73mm x 73mm x 49mm, with top layer of acrylic with engraved numbers,
If the film is missing from the acrylic, I use this special laser engravers tape,
Don't ask me about other alternatives as I haven't tried any.
This picture clearly shows the transparency of the laser cut through 6mm acrylic,
If your first cut is too short... Take the second cut from the longer end... LBD
