Blueprints are the last of my concerns. What I think will be hard to do is to implement a full supply chain into a single space-travelling factory, including sourcing and refining of raw materials. But, regarding the blueprints, it now occurs to me that our "recipes" are made to work on our planet. Another one may lack some "ingredients" or have atmospheric conditions that could mess with the chemical reactions we use here. So we would need an advanced AI able to adapt production to the environment it finds.
