Satisfactory 4 to 3 load balancer
With 4 input belts of 480/min each (a full Mk4), the build with the best result is the Matrix: 4 splitters and 6 mergers, with 480/min on each of the 3 outputs.
Step by step
- Bring in the 4 input belts (I1, I2, I3, I4), 480/min each.
- Column 1: 4 splitters into 3.
- Column 2: 3 mergers.
- Column 3: 3 mergers.
- Connect the 3 outputs to the destination lines: each carries 480/min.
Rate per segment
| Segment | Carries | Fits Mk4? |
|---|---|---|
| Input | 480 | ✓ |
| Each of the 3 parts | 160 | ✓ |
| Chain with 3 parts joined | 480 | ✓ |
| Each output | 640 | ✗ |
Other ways to build it
- Butterfly with sink: 16 pieces, 480/min per output
- Looped butterfly: 17 pieces, 274.3/min per output

What it is
A load balancer is a set of splitters and mergers that takes N belts and delivers M belts at exactly the same rate, no matter how much each input carries. There is no “balancer” piece in the game: you build it from regular pieces.
