[simpits-tech] to MARV re: RP

[Jim K.]

Marv,
The quality of RP prototypes seems to rely on the machine being used and 
what type of RP is being used.  There are several different RP methods and 
they do produce different results.  I think you can change the quality 
outcome of a part via your drawing and/or the settings in the RP machine 
itself and the way you make the part is critical as well.  I.E., you have 
to choose the correct orientation of the part from which to start.  I have 
some RP parts here and the top final surface that was generated is as 
smooth as glass but the sides have that "grain" to it.  I don't think FDM 
parts have this grain to it but I'd have to check.  I just brought this all 
up as an option.

hmmmmmm, thinking here:  What if you made a mold of the part via a CNC 
machine and then melted lead or some type of plastic into the mold to make 
your own parts???
