A pre-designed and shareable construction plan in the game Factorio that facilitates the efficient layout and replication of a specific type of conveyor system. This design centers around the use of “blue belts,” a high-throughput transport mechanism that moves items between machines and storage. The resulting saved design can be placed elsewhere in the game world, automatically queuing up the necessary materials and construction tasks for automated building by construction robots or manual player placement. For example, a complex intersection of these high-speed conveyors designed for even distribution of resources can be saved and duplicated easily.
This mechanism allows for significant time savings and standardization across a factory. By using a reliable high-throughput conveyor design, bottlenecks are reduced, and factory output is optimized. Furthermore, sharing these designs within a multiplayer setting enables collaborative base building and streamlined expansion efforts. The concept gained prominence as players sought to optimize factory layouts and share their knowledge of efficient resource transport methods within the game’s community. This became essential in the game due to the game’s complexity.
