content: Smartphones, game consoles, cars and TVs are ubiquitous but you don't see them being sold at gas stations either. Ubiquitous in this case is not meaning the general consumer public but instead the smaller Maker and Hacker markets. The population who would make use of these machines in a desktop manufacturing capacity do either already own them, have regular access to them via a MakerSpace or use a service to get their parts made. You must have a need for a 3D printer to have a reason to use/own one, just like a USB storage device. I own s 3D printer as well as a laser cutter and use them both frequently to prototype creations for small runs that I sometimes sell. I don't have a publicly visible image or storefront so you wouldn't know I was manufacturing items unless you are in my channels. Ubiquity does not equate to visibility. As an interesting side note though, lasers have reached the point of invisible ubiquity and can be purchased alongside your cigs and PowerBall tickets. I have bought a number of lighters and flashlights at gas stations that have red diode lasers in them. It's an interesting thing for me because I remember being a kid in the 80s and going to swap meets/flee markets and thinking to myself that one day you will be able to readily purchase a laser in a market like that. It was a prophecy that did come true since these diode lasers are everywhere now. Count up all the lasers you have in your house and be amazed. I can count 35+ in my home ranging from 1 Mw Class Ia through 40 Watt Class IV. They're in everything it seems. I'm probably missing quite a few with the ones I don't even notice anymore.
