-Miniaturization 1 is a (new) prerequisite for modular armor;
-Miniaturization 2 is required for Mk2 components (shields and batteries).
-Enables building miniature versions of the three assembling machines, which are 2×2 instead of 3×3 but more limited in their capabilities. Also adds a mini electric furnace – handy for saving space and requiring less retooling of your old burner furnace setup – if you can wait long enough for the research, anyway.
-Limiting an assembler to one ingredient is… pretty limiting! (Level 3 assemblers can handle three ingredients which is enough for many common items.) Normal assembling machine included in picture for scale.
