Correct. And where are iPods and portable MP3 players now? If not dead, have become a worthelss commodity market. The patents on SLS have expired, and that is now the next big thing in 3D printers. If you have ever tried to coax a consumer FDM 3D printer into a working reliably and repeatably, you'll understand. The point I'm trying to make is that if you are looking to invest, then invest in the big companies that make the huge and expensive commercial and industrial 3D printers. The consumer 3D printer market is an over-saturated cut-throat me-too race to the bottom, and will only get worse.
