I had the opportunity to work with “Flexilase” for a project at the office, and thought I would share the settings. This material engraves well, though not as cleanly as rigid 2-ply acrylic. It is slightly flexible so you can stick your item to a curved surface. (The adhesive seems very strong, but I only applied it to flat acrylic, which is no challenge.)
I would only do black & white designs, this material is not intended for engraving at variable depth.
It’s $14 for a 12" x 24" sheet, but unfortunately you’ll pay about that much in shipping, too.

(LPI 675 seems high but short of that I got banding artifacts.)

(I like this stuff and wish I had a bunch of colors. Too bad there aren’t more vendors that serve the needs of small orders. If I could get 10 colors of this stuff shipped to me in a Priority Mail envelope, I’d totally bite.)
