The question is how much capital is required to start. At the moment, you need to either be a huge corporation or (like Tesla) market yourself well and get a ton of investors to start making cars.
If the price of building a small factory dropped enough, maybe your local library/school would have an open factory space where people go to print custom cars.
If you don't want a custom car, it'd probably be cheaper to buy one though (partially because the availability of such printing would force manufacturers to drop prices).
