Tell you what Jeff, if you stop calling it RP, we can stop discussing what
else to call it!

The way I look at it - RP (Rapid Prototyping) is what I do, AM/SM
(Additive/Subtractive Manufacturing) are the processes I use to do RP.
Then there comes the whole CAD/CNC machining, 3D Printing (SLA, FDM,
etc...) as how the AM/SM processes are accomplished. And yes there was a

thread about this a bit ago - it seemed to dissolved into a circular
discussion based on point of view :-)
