Actually, we have three scale factors, one for each of X, Y, Z. In the X and Y directions,
there is a scaling for part growth combined with another for machine calibration (performed
at the beginning of every build).
the expansion is not uniform across different features. We have a good idea of what the
scaling should be for a given part, but in the end, it's our experienced LOM operator who
makes the final call.
