Excellent post on tool-paths for a popular automated concrete placing method called shot-crete in this case. As opposed to a gently placed layer the mix is β€˜extruded’ at high velocity with equal mechanical precision to 3DCP but quite a bit more kinetic energy at the extrusion point (not measured officially just guessing).

A guy built a super cheap robotic arm at home with 3 degrees of freedom. The complexity and frequency of these projects only keeps growing!
