Actually that would not be necessary as this is just a discussion -- I'm
a currently LOM & SLA user and not interested in purchasing other
equipment. However I have used FDM, SLS & SGC in the past (about 3
years ago) so naturally still interested in all RP. I was not aware of
a "quickcast-esque" build style for the FDM. Is the material usage low
enough to justify using the ABS (expensive at around US$4.70 a cubic
inch last year) versus the assumably cheaper wax? Or is it simply a
speed issue? Is this style applicable across the Stratasys line or only
certain machines?

As far as coming to Malaysia, feel free to call me. I don't mind
showing off my lab and then talking RP over a few cold ones!
