Stack of 12 foundries, 3 levels of 4. The original design of this was to have 24 foundries (see picture), however it wouldn't fit in the blueprint machine so this is just half of it.

This blueprint uses tier 5 conveyors and requires access to aluminium. See https://satisfactory-calculator.com/blueprints/index/details/id/1487/name/Foundry+Stack+for+tier+4 for a variation that uses tier 3 conveyors.

To make it a 24 stack again:

1. paste one half,
2. delete the side of input lifts/splitters,
3. paste the second half,
4. reconnect the input lifts/splitters from the second half).

Power point is under the input lifts.

Logistics

In the unaltered 24 stack form:

• 2 x 2 inputs under the center (each input services 12 foundries)
• 3 outputs (each output is merged from 8 foundries)
• This is suitable for recipes no greater then 50pm input (50x12 = 600) and 100pm input (100x8 = 780 + 20 excess)

You can also alter the design to have 2 outputs (each output is merged from 12 foundries, suitable for recipes with 60pm output). To do this, delete the central bottom merger, and add lifts from the other outputs to connect them to bottom output row.
