The use of Z-axiz cement extrusion is, to me, pedestrian in vision. Id much rather have a 6-degrees nozzle that can do organic shapes in the landscape, and especially sub-terraniean tunnel dwelling: Carve tunnels/cave outs powderize what you carve out, mix it into slurry cement augmented with various fortifying elements, grwo a mycelium very porous - loofah like spongy wall membrane and spray into it the slurry of aerogel-particle-insulating filler materials for fire, radiation, weight reasons and the robot has multiple nozzles on arms that have spray heads like mini cropduster apparatus to spray the foam in. But you use soft robots to expand the foundations and run fiber and other wiring/cabeling/ventellation tubes through the loofah then spray around it. where the spray head is on a steerable flexible sof robot, and the slurry is pumped through one of the many tubes of the Mars HydraPed. https://www.youtube.com/watch?v=eLVAMG_3fLg https://www.youtube.com/watch?v=eLVAMG_3fLg
