I see items made out of baltic birch plywood all the time on the internet and just recently tried cutting some. I wasn't too happy with the results. I've made ornaments out of 1/8" alder that really looked nice. I wanted to try the baltic because it is cheaper but the edges char. Do most people put a coat of finish before they laser cut them. I imagine that the unfinished wood will get dirt and smudges on it that will not easily be removed.
