In the lab I work in the vast majority of our CNC'd robot parts are lasercut delrin. So, yeah, it works.

Turn the power down low, do multi-pass if you have to (on 1/4'' delrin, we usually do 3-4 passes). I don't know what model lasercutter you have, but I can stop by the lab and tell you the specs on ours and the standard settings for various thicknesses. We can get up to about 1/4'' thick before the melting starts to get unacceptable for our required precision.

Make sure you have a nice exhaust system set up so you're not breathing in any of the fumes, though.
