yes but here we are talking about the style of buildings possible with such tech not just that it exists.
Under the Venus project, you hawe an "city builder" printer ... the actual thing is the automatic building capability of high structural resemblence and acurracy. Actually, you can make an printer head for multiple materials printing at the same time, making building werry easy and whyte the printing mass height you can achieve an hardenning time to the moment the print-head comes back to the place ... actually, some metal things are made whyte the help of hi-power lasers in a bank of metall-dust ... just hardened afterwards ... so ewen an werry old candel-printer ... only, that lasers could not be powered by solars (not in our 50+ years as for they basic way of absorbing fotons to produce electron-mowement in the P-N- base structure ... ), its too low power from them (and not too stable too). But ... Russians already produce LED-like structured low power needed lasers (still a big energy-eater, but has the potencial in further developement). As Printed plastics-based electronics on a chemical base (from batteryes, solar pannels, transparent LED-s ...) i think its an future age of Printer-society before us ... well, still a little to far from our lives as we are organized and structuralized, but it will be ... if we really dont destroy our selwes .... in that case: Cameni !!!! How did you know whats gonna happen ?! ... this game of yours is not a game, its a sim. for preparing our children for REAL ANTENWORLD !!! ... I wonna a creo-capsule, right at the window !!!
