Surface roughness for different processes and orientations

Dear All,
A few years back, Phil Reeves (then of Nottingham University) did some work
looking at surface roughness of SL parts for different build orientations.
Has anyone done or seen any similar work for other processes? I am
particularly interested in:
SLS (glass filled nylon)
Z Corp 3D printing (plaster)

but would also appreciate any other related info.

Many Thanks
