Secondly, the modular design allows for transport (thus UPS) efficiencies not possible with some other designs. Each building block unit is fully self-contained 62.5sci/min factory requiring 250MW of power.įirstly, it allows you to scale from 1 science per second up to gigafactory size with exactly the same factory design. It takes in raw materials from 3-8 trains and researches science. Gears via Main Bus always seemed lacking, even if I put extra lanes in.This is a modular, tileable UPS-friendly sci/min megafactory design blueprint. The places that gears are needed are in great quantity, such as belt manufacturing arrays, it's easier to make them onsite by diverting iron plates in. (Many products require both iron plates and gear wheels) In place they are used sparingly, 1 gear factory provides more than enough for an assembly line, and they can be placed such that the iron comes on half the assembly line, and the gears are placed on the other half. Gears: While the ratio of iron plates to iron gear wheels is advantageous ratio-wise, (2 plates makes 1 iron gear wheel), I've found (through real experimentation) that it is much more efficient to make Gears locally.They are also inefficient to belt - 1 copper plate makes 2 copper cables, inflating the need for belts by two-fold! Far better to make these locally as needed. Copper Cables: While they are high in demand for green circuits, they are used in almost nothing else.When you find yourself needing an extra component that is used for very few items, (like stone, stone bricks, or coal), either run a line to the side of the main bus, ending it at the assemblers, or carry the materials in via robots & requester chests.Place Concrete or Stone Brick under a couple lanes of your bus & in one of the spaces between lanes (at a minimum) since it gives you a speed boost when running.Add more production to fill your belts with intermediate products: Copper & Iron Plate, Steel, Green Circuits, etc.When you get robots, you can easily extend the bus with blueprints.You can replace splitters and undergrounds similarly by just placing upgraded versions on top of the old, (without the need to deconstruct them).

The easiest way to upgrade belts is simply run along the line, holding down the mouse button to place belts on top of existing ones.(I normally skip red belts and go straight to blue to save myself the annoyance of replacing the bus 2 times). Upgrade belts when more throughput is needed.

Make sure to re-balance belts after you split from them.

Done! Two science packs made efficiently and traveling together on the same belt!.

For the belt furthest from the assembler, split off green circuits.

Place inserters as per screenshot - only inserters need long-arms.

Place 2 rows of belts along the gear, inserter, and belt assemblers, and place the snaking belt that leads to the Green Science assemblers as per screenshot below.

Place these one tile away from the Red Science output belt.

Place Assemblers: 1 crafting Iron Gear Wheels, 1 each for belts and assemblers, then 8-10 for Green Science.

Green Science needs belts and inserters to craft. Neatness matters! Make sure the empty side is across from the inserter! (As shown).

For the belt close to the assembler, split off half a lane of iron plates.

For the belt furthest from the assembler, split off copper plates.

Place a regular inserter and a long armed inserter to feed each Science assembler.

Place 2 fast inserters in, and 1 fast inserter going out of the Gear Wheel assembler.

Place another belt along the output side of the assemblers. Place 2 rows of belts along the assemblers.Place Assemblers: 1 crafting Iron Gear Wheels, 6-8 making Red Science.Red & Green Science Red Science needs Gears & Copper to craft. If your lanes are getting chronically unbalanced, consider putting in a proper 4 lane belt balancer, which splits products equally:Ī proper 4 lane belt balancer, (on iron), which splits products equally next to the space-saving solution (copper) which is a stop-gap solution when you have less space.Īnother example of splitting two products off the Main Bus: After the split off at lane 4, splitters allow movement of product to go all the way from lane 1 to lane 4, replenishing product on all lines. Therefore, use 3 splitters to divert resources back to that lane.Īrrows show direction of product movement. On a 4 belt line, you need to make sure the furthest belt from the split can feed into the edge you split from. On a two-belt line, (like steel or plastic), use a regular splitter. Balance After you split off to the side, you will need to balance the belts again to feed more back to the lane you just took from.
