About this build

The complete Factorio-SAT balancer collection in one book of 308 blueprints: balancers for every combination from 1 to 8 input belts and 1 to 8 output belts, in yellow, red and blue versions, both the most compact and the narrowest designs. A balancer spreads every input belt evenly over every output belt, so a factory line downstream gets the same share from each lane of ore or plates. These were found by Factorio-SAT, a program that uses a SAT solver to search for the smallest balancer of each size.

A few of the largest odd sizes (such as 7 to 5 or 8 to 7) are still missing; the program has not solved them yet.

Before you place it

  • Clear a space of at least 10 × 12 tiles for the largest blueprint in the book.
  • It works in the base game without Space Age.
  • It is large: construction robots will place it much faster than building by hand.
  • It was made in Factorio 1.1; the game converts it when you import it, so check it once after placing.
