I wonder if anyone else knows the answer to this (it may count as a spoiler so Kyzrati won't be able to answer?): is this fab with matter containers next to it in the caves a relic of the earlier fabbing system, where you had to feed matter in, or is there still a way to use it? (Status on the fab reported 0 matter available.) I didn't want to throw this game by messing around trying to feed matter into the recycling unit and see if it went to the fabricator.
