Advanced Lab

Lore & Background

In the Factorio world, the Advanced Lab is less a single invention than a threshold. The basic Lab proved that science packs could be manufactured and consumed in a loop, but it was the Advanced Lab that demanded the player look beyond the mine and the furnace. To build even one, you must have already mastered the oil field—drilling, pumping, refining, and converting light and heavy oil into the glossy, uniform bars of plastic that snap into the lab's housing. That single requirement reshapes the factory's geography: pipelines now snake across the terrain, refinements hum beside the assembling machines, and the once-quiet green plains are threaded with the slow, viscous flow of petroleum. Fans often describe the first Advanced Lab as a quiet victory. The recipe is not complex, but the *chain* behind it is. Every iron plate, every copper plate, every circuit, and every plastic bar traces back to a raw resource node, and the player must now keep all of those lines fed simultaneously. The lab's blue indicator light, pulsing steadily as it devours two science packs per second, becomes a small beacon of progress in an otherwise grey-and-green industrial sprawl. Within the broader narrative of the game, the Advanced Lab is the gateway that makes the advanced science pack—and eventually the military, chemical, and signal science tiers—feel achievable rather than abstract. It is the lab that says: you are no longer a lone survivor tinkering in a shed. You are an engineer, and your factory is a living system that must be balanced, expanded, and defended.

In Their Own Story

The rain had stopped, but the ground still glistened. Klonan stood at the edge of the oil field, watching the new pipeline snake toward the refinery like a dark vein laid across the grass. Somewhere behind him, three assembling machines clattered in unison, spitting out plastic bars with a soft, satisfying thud. She hadn't slept in two days. The basic Lab was still running, still consuming, but the research queue had grown too long, too hungry. One lab was a candle. She needed a furnace. The Advanced Lab recipe glowed on her screen: thirty iron, ten copper, ten plastic, ten circuits, one lab. She'd built the first one at dawn, set it down beside the old Lab, and watched the science-pack indicator flare from a single blue dot to a bright, steady pair. The research speed doubled. The queue shrank. She wiped grease from her forehead, listened to the oil pumps groan in the distance, and smiled. The factory was no longer a survival kit. It was a machine, and it was hungry, and she was going to feed it.

Reader's Guide

The Advanced Lab recipe requires 30 iron plates, 10 copper plates, 10 plastic bars, 10 circuits, and 1 basic Lab, all assembled in an Assembling Machine 1 or higher. Upstream dependencies: Iron plates come from iron ore via a furnace. Copper plates come from copper ore via a furnace. Circuits require 1 iron plate + 1 copper plate in an assembling machine. Plastic bars require 1 light oil + 1 heavy oil, both products of the oil refinery fed by crude oil from a pumpjack. The basic Lab itself needs 20 iron plates, 10 copper plates, and 10 circuits. The typical bottleneck at this stage is the plastic bar line. Oil refining is slow, and the refinery's output of light and heavy oil must be balanced so neither product backs up. A common early mistake is building only one refinery and then discovering that the plastic bar assembler is starved half the time. Scaling to two or three refineries, with a buffer of storage tanks between the pumpjack and the refinery, smooths this out. Circuits are the second pressure point. Because both the Lab and the Advanced Lab consume circuits, and the Advanced Lab also consumes the Lab (which itself consumed circuits), the effective circuit demand is roughly 20 per Advanced Lab. Ensure your circuit assembler has a dedicated, uninterrupted supply of iron and copper plates. As the factory grows toward the advanced science tier, the Advanced Lab is typically replaced by the Production Lab. At that point, the iron, copper, and plastic infrastructure you built for the Advanced Lab becomes the backbone of the entire mid-game factory, and the oil pipeline you laid for plastic bars now also feeds chemical science and later, space-age research.

Did You Know?

• The Advanced Lab is the first building in Factorio that requires a product of the oil refinery, making it the gateway that forces every player to build their petroleum infrastructure.
• Each Advanced Lab consumes 2 basic science packs per second, exactly double the basic Lab, so swapping a single Lab for an Advanced Lab doubles that station's research contribution.
• Because the recipe includes the basic Lab as a component, building Advanced Labs in bulk temporarily consumes a large number of Labs, which in turn spikes circuit and iron demand in a way that can bottleneck a small fact
• The Advanced Lab's blue science-pack indicator is visually identical to the basic Lab's, but the doubled consumption rate means the pack icon depletes noticeably faster, a subtle in-game cue that the research engine is w
