I will leave the following for troopy:
contraption works only inside, cost as much as a hadrian x, builds cement walls with no rebar can't build space for windows or doors and when it does it also needs manual labour to place elements to print above a window top opening or atop a door opening, walls are not wrench tested let alone fire tested nor isolated like wienerberger 2 in 1isolated bricks and on and on, you need time and men and cranes to position the contraption....etc....etc..
troopy what do you think?
will these cement walls crack like an egg?
