Lab

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

Production

Labs take two inputs: Electricity and Science pack.

As of 0.15, there are seven Science packs:

Labs output: Research progress.

Each force can research one science at a time, but can use many labs for faster results.

(For 0.14 there are four Science packs, Science pack 1, Science pack 2, Science pack 3 and Alien science pack)

0.12.6:
- The research speed of a lab is now not dependent on it's 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 blueprint.

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