The majority of the body I modeled in Rhino. I found a blueprint or spec sheet with all the measurements and angle. Then I sculpted the Skull in ZBrush. I'm pretty sure this was printed in a large format resin printer. It's possible I'm not remembering correctly if it was a resin printer or not but I do know that it wasn't printed on a regular size printer because I specifically asked if I would need to cut it up to be printed and then assembled.
I do know that everything fit pretty well with only some minor sanding in a few spots. I have asked for photos several times.
