The RG models in particular are insane!
Check out this video of Adam Savage making one: https://www.youtube.com/watch?v=xfmD1yYqP6k

> The leg inner frame is molded in sequence in ABS plastic, which is semi-crystaline and only bonds to itself. The second plastic is in Polypropylene which is fully crystalline and also only bonds to itself. This creates working joints without having to have radically different thermoset temperatures because the two plastics chosen simply don't cling to each other. No additional coating of release agent is required at all, it just uses the plastics' innate properties.
That's awesome!
But I don't know enough about this process, by a large margin. I didn't even know co-molding was a thing.
The build time doubled as I was marveling at the precision involved and the thought put into the design and instructions.
I can only imagine what the larger "perfect grade" stuff is like.
My kid impatiently wanted his robot already...
