  • $\begingroup$ How freely can the printable species be designed? Part of your question of a working ecosystem hinges on a concept of reliance of one species on another (e.g. plants needing CO2 and providing O2, and animals needing O2 and providing CO2). But intelligent design of the species can significantly simplify that process. Are you trying to stick to an Earth-like ecosystem complexity/variety, or are you open to a significantly simpler version that only works based on intelligent printer designs? $\endgroup$ Commented Aug 14, 2025 at 1:17
