Mass spectrometer

This is the construction part of the fab. It takes elements and directs them atom at a time to specified locations.

This page includes time to build per mol of product, which in turn shows the frequency of the atom stream at the deposition end.

Scaling up might involve a lot of deposition ends.

We decided the average mol of raw material is 54g so as a rough guide, 1kg is 20mols.

There's no getting away from the fact that we need a lot of these. Each beam can handle 1E10 atoms/s at most, with 1GHz discrimination, whether it is the 3D printer unit or the refinery. So long as the size of these is small enough, production will scale to usable periods.
