Developing 3D-Printing Tech for Cars (medium.com)
New submitter kynthelig writes: There are a hundred reasons why 3D printed cars might not work. But that's true of almost any great idea in tech. A few automotive entrepreneurs have developed a vision — along with actual physical cars — that rethink the assumptions about how cars get built. The result has a smaller environmental footprint than either conventional or electric cars, allows for faster innovation, and retools car manufacturing into a local, community-oriented business. The car revolution isn't just in automating them: it's also in how we build them.
Cardboard also has a lower environmental impact than all that crap they use for cars.
That does not imply that if I built a car out of cardboard that could pass safety regulations, it would still have a lower environmental impact. All that required equipment might be the big factor there, not the legendary inefficiency of automobile production lines. ;)
