Science packs put into the front lab will be passed to labs behind it.

Labs are buildings that perform research for technologies by consuming science packs. Use of a lab is required to progress in Factorio.

The player can only research one technology at a time, but can use multiple labs for faster results. The speed bonus of labs when Lab research speed is researched and modules are present can be calculatd using this formula: research_bonus * module_bonus = speed_bonus; the percentage bonuses have to be converted to decimals (e.g. +140% = 2.4) before the formula is used.

Production requirements

Calculating the number of science packs needed per second is straightforward:

• Adjusted Cycle Time = <in-game Cycle Time> /((<in-game Lab Research Speed> / 100) + 1)
• Packs per Second = 1 / (Adjusted Cycle Time / <# of labs>)

Thus, for a 10 lab setup, researching Nuclear Power (30 second cycle time) with Lab Research Speed 4 (140% bonus), the math would be:

• ACT = 30 / ((140 / 100) + 1)
  • = 12.5 seconds, adjusted cycle time
• PPS = 1 / (12.5 / 10)
  • = 0.8 Science per second

This means 0.8 science packs per second, of each type, would need to be produced to continuously supply the labs.

History

• 0.12.6:
  • The research speed of a lab is now not dependent on its electricity consumption, and can be scripted.

• 0.12.0:
  • Lab research is now continuous; Science packs now have progress bars.

• 0.9.2:
  • Labs are now named after early access backers when built from blueprints.

• 0.7.2:
  • Changed the recipe of Lab to require 4 transport belts, down from 5.

• 0.6.0:
  • New graphics.

• 0.2.7:
  • Contents of the Lab is now shown in the entity info.

• 0.1.0:
  • Introduced
