Neat! I was worried it'd be another 3D printer, but I was happy to find out it's entirely different process.
I was not familiar with pressure molding before, so I was wondering how "4 atmosphere" pressure they mentioned compares to industrial processes -- it sounded pretty low, my bicycle tires have higher pressure than that.
Turns out that yes, they must be using "low pressure molding" process [0]. The wikipedia says "very low pressure, typically 50 to 200 psi (3.5 to 14 bar)" and the pressure mentioned in the video (60 psi / 4 bar) seems to be right in the middle of that range.
