02 — Blueprint String

This is a valid Factorio blueprint string generated from blueprint JSON and zlib encoding. It contains 15 assemblers, 148 belts, 36 inserters, 12 beacons, six substations, and a small combinator note with the 900/min target.

03 — Why It's Optimized

9:6 assembler ratio

Nine assembling-machine-3 cable makers feed six electronic-circuit assemblers: 45 copper cable/sec into 15 green circuits/sec.

Inline cable spine

Copper cable is produced beside the circuit machines so the short-lived, high-volume cable never has to travel across the bus.

Beacon-ready shell

Twelve beacons and six substations reserve upgrade lanes without changing the base 900/min rate until you module the block.

// throughput math

Six assembler-3 electronic circuit machines at 2.5 crafts/sec each produce exactly 15 circuits/sec, or 900/min. The nine inline cable assemblers produce 45 copper cable/sec, matching the three-cable recipe demand without routing copper cable across long bus lanes.

04 — How to Use

  1. 01

    Copy the blueprint string from the block below.

  2. 02

    Open Factorio, load your save, and press Ctrl+B to open the blueprint library.

  3. 03

    Click Import String, paste the copied blueprint, and confirm the import.

  4. 04

    Place the array on a cleared 19 × 39 tile pad with power coverage connected to the substations.

  5. 05

    Feed copper plate into the copper lane and iron plate into the iron lane; the inline assemblers produce cable locally.

  6. 06

    Connect the output lane to your bus or train loader and let the yellow-belt circuit output saturate at 900/min.

// verify before placing

Want to inspect the string first? Paste it into the Factorex Blueprint Decoder to confirm the entity count and footprint.
