Someday, nearly every home will have a 3D printer. When people need a new pair of shoes in just their size or in their favorite color or need a replacement part for an appliance or a tool, they will be able to simply pay for and download a file and print what they want on their own 3D printer, which will be as ubiquitous in homes as microwaves are today.
As for art, printing even larger sculptures than I’m able to today will be far more available and affordable, as will more exotic materials.
But what if a mechanic shop could just print it? Using quality filaments, mechanics can print the part, install it on the vehicle, and have it back to the owner in less than a day. Eventually, this could be done with metal parts with direct metal laser sintering. It would make car repairs cheaper and faster and put more money in local mechanics’ pocket—instead of their having to pay auto manufacturers for parts.
