I watch some of the machinist YouTubes so can venture a guess… Molds need super high precision CNC machines because any flaws will show up in the parts. So think expensive. And they aren’t going to be giving away machine time any time soon. On guy I saw who was being interviewed had such a machine he bought second hand from (I believe) UC Berkeley and it was something like one out of three that were ever imported to the US. I guess it was a popular machine to make cell phone cases back in the day and Berkeley ended up with one for some reason.
