I've used nylon SLS for lab and commercial optical work. It's strong and you can tap it. It's much cleaner than dealing with resin prints. The quality is fine if you're making simple polygonal shapes and unless you need really fine detail it's enough. You can also do things easily with SLS which are really annoying to do with printer technologies that need removable supports, like cavities and overhangs.
