They’re poised to print a real functioning human liver this year and a heart within a few more years. That’s no cottage industry.
Sorry, I didn't mean to suggest that what they were doing is a cottage industry, I was referring to a family business in Maine making high cap magazines and other parts for guns, fishing, etc.
The more I think about it the more I like the things a family could do with a 3D printer, and from what I am seeing online, tehy are not all that expensive.
