I am a grad student at the Arizona State University. I am
currently working on characterizing the surface finish on rapid
prototyped parts from the GEnisys m/c( from Stratasys).
I would like to know if any of you know of a surface roughness measuring
device which can be used for the rough surfaces produced by rp m/cs.
I am talking of RMS values in the range of 200-1000.
