I have what are basically toy 3d printers capable of 1 micron precision...
Cool. Build 10 pieces and fit them together with sub 10 micron precision.
Ok, and once that's done with the high level of repeatability and quality I've done it a thousand times, then what?
Scale that up to a 4 ton production-ready consumer vehicle without introducing defects, I imagine
The heaviest Tesla is around 2.5 tons...but that's beside the point.
The scale doesn't matter. In fact, taking a desktop process and industrializing it makes it more accurate and repeatable - especially in a large-item manufacturing setting.
The best argument against the 1 micron requirement is that it's unnecessary from a practical standpoint. I completely agree with that, for sure.
