3d printers have the potential to flip some boards, car parts printed on demand on site, no more waiting days to weeks. Houses built in a week, with designs that allow vertical add ons, upgrades to phones by recycling previous ones, in the near future 3d printers will be as common as tvs. Also with food, still really early on that but basically Star Trek replicators for corporate stuff. McDonald’s at home through a 3d printer, you just pay a licensing fee and provide material tubes. Web3 is going to be interesting.
