Dear Joe DeGuglielmo,

Your explanation of the SLS process means that only the surfaces of a
prototype are porous but not the whole part. If that is so, then how
works the RapidTool process? The "green" and "brown" parts must be
porous to be filled with copper. Does it mean that the SLS process
melts the plastic but only sinters the metal powders?

Dear Ian Gibson,

At the present stage of the process, is that a matter of choice, that
the powder melted or sintered? Melting for Nylon, Fine Nylon,
Composites, etc. and sintering for metals?
You wrote: "Slice thickness is a nominal 0.13mm, which once melted becomes
0.1mm." The DTM guys wrote the minimal layer thickness 0.003in
(0.076mm), the maximum 0.02in (0.51mm). The 0.13mm is the commonly used thickness?
