Building a model car by pressing body panels in metal

[Hobbes]

This guy has scaled down the production process of a car: he created form tools (on a CNC mill, I think) so he could press the body panels in thin metal foil:

Very interesting, specially for me, coming from an industrial background where we did it for real. 

I wonder what the foil he used was, and would it retain its shape over time? In the 1:1 world the sheet is held at its edges and the dies produce enough force on the material to take it past the yield point, so afterwards it retains its shape.

I wonder how he joined the various panels together too, some kind of glue I guess?

The plastic parts appear to have been 3D printed (they have what look like the remnants of printing artifacts/lines on them).

The metal panels are glued using some kind of hot glue gun & then, it looks like, some kind of metal/body putty. However, most of them appear to just clip into place but he may not have shown that more than the once, as a demonstration of process.

The molds for the metal parts appear to have been cut with a CNC mill into a hard wood, engineering resin (like Renshape) or both. The white truck parts look printed in sintered nylon, which is a relatively cheap but strong material. The dark gray truck parts seem to be printed in PLA or ABS.

Pretty interesting process!
