Not just traditional industry My brother owns one. He's always willing to sell a few parts if someone asks for them. I think that the hobbyist who owns one of these is going to be a middle ground between the manufacturing industry and the tinkerer, and it's likely to enable types of small businesses that we've never seen before. I think you're right that, at least in its current state, it probably won't reach PC levels of adoption. That said, it's hard to watch one of them in action without imagining what you could make with it. They may not be ubiquitous in the coming years, but they won't be uncommon either.But I can see it drastically changing manufacturing. I am sure there are plenty of components shipped about that could be printed as needed at a lower cost.
