One of the deep and subtle magics of fabrication is how many ways you can get approximately the same result with different procedures. It’s a bit like cooking, where the choice of whether to bake or broil, pan fry or deep fry, can have a profound effect or make little difference at all depending on what goes in and the desired result. Having a laser on hand means I can fiddle with my methods and iterate a bunch of different solutions each with minor tweaks until I get the result I was searching for. Also, with the coming laser singularity (when lasers become more common than printers), more materials and toys are available for added lazing satisfaction.
