I believe @elonmusk stated molten alloy injection for Model Y rear underbody takes ~40 milliseconds
I don't see additive manufacturing being able to compete with state-of-the-art die casting on critical metrics of mass-volume production: cost, ease, & speed of manufacturing
Elon Musk@elonmusk· Oct 8, 2020@TashaARK Additive manufacturing of parts is still far too costly for cars, but can rapidly create tooling to accelerate pace of innovation.
It’s already sensible for rocket engine parts. To the best of our knowledge, SpaceX is 2 or 3 years ahead of other companies in use of additive.

Yeah, it’s not a contest. Advanced casting crushes best-case 3D printing, but casting doesn’t work well for complex enclosed volumes & high strength or high temp alloys.
