If the 2500 hour number in the story is not a misprint, that means it takes 104 days nonstop to generate the body?
It’s a start. It is a bit of a disruptive technology, for firearms and soon cars. Eventually with an open-source approach and a cottage industry, cars like this project would overtake the current industry within 15 years.
If they can eventually get around to mass production, it will probably take about the same time that it currently takes to produce a vehicle.
The advantage that 3D printing might have is that there could be significant savings in transporting only the raw material, instead of having to transport parts.
