It is cool, but the size likely makes it too large for "metal 3D printers" (for now).
Cleanup of "support" structure from DMLS parts can be a nightmare, not to mention the challenge of maintaining accuracy and tolerances or such a large part.
I did not look to see how large DMLS machines have become though.
The optimization process is great, but beyond creating a prototype/concept, I'm not sure this is the best method for producing car frames.
Looking at the frame, I see a layout which could largely be formed via welding (like a roll cage).
Outside of tubular structures, a more traditional frame building process of punching, stamping, forming, pinching, and welding flat stock could create much of the structure.
Maybe make a few "printed parts" and bolt/weld them to the more traditionally produced parts?
It will all come down to accountants in the end. What is the cost of "printing" a one piece frame vs. the cost of welding tubes, or forming flat stock into a similar shapes?
The seat makes no sense. Is that a $20,000 3D printed, foam seat? I'd prefer the traditional inexpensive seating option, then I'll have money remaining to actually buy the car!
