From Dual Universe Wiki
- In Dual Universe, each time a player wants to produce a construct it must first be built manually. A blueprint can then be generated from this construct, allowing it to be mass produced and even sold, should the owner choose. Blueprints can be used in combination with specific industrial units to quickly produce constructs that could otherwise take large amounts of time to produce manually. A blueprint master can be used an unlimited number of times, and blueprint copies can be created from them which only have a limited number of uses.
