Again, scalpels have been around for hundreds of years, and yet home surgery kits aren't the number one seller Amazon. If me telling a techno-utopianist (with the magic phrase "you don't know, in 30 years everything could be different!) that they're overlooking a glaring problem is "off putting" to you, so be it.

None of what you said in the next three paragraphs has anything to do with what I just said. The problem is not the fucking accuracy. A Wanhao D7 could handily achieve the accuracy, and those are like, $500. The problem is Most people aren't orthodontists. They also don't have access to medically sterile environments, nor is making a medically sterile environment in a home feasible for any reason. Putting dirty, vaguely mouth shaped things into your face for long periods of time is not going to lead to a brighter tomorrow of home dentistry. It's going to lead to people with a lot of infected, fucked up mouths. This isn't some "fascinating glimpse into the future," this is a research project picked up by shitty clickbait blogs.

I'm incredibly excited for where 3D printing is headed. That's why I build them, and am looking to enter the market soon. I'm not interested in clickbait fluff. Now that sentence is quite off putting. However, people going full British because they tried to make their own dental prostheses at home is also quite off putting.
