The tech levels available in locus-1 are one of those oddities that the way crafting works in starfinder I think. Basically if the corps or somebody gives you access to those patterns then your fabricators can use UPB to make them. So you can potentially have very small bases that are heavily corp backed that have ability to make almost anything. You don't need some massive manufacturer base or work force. A hand full of skilled techs with access to the patterns and a fabricator and sufficient UPB can do almost anything.
