This guy DIY’d it way back in the early days of concrete extrusion. He actually let a college class i was in see it. It was definitely an involved project and the result was pretty rough around the edges.
Unfortunately I don’t remember much about the type of mix he used or the pumping system. So I can’t guide you in the right direction.
