For the Envisiontec machine the support and build material is the same as
only one VAT
what you may be experiencing is when the parts aren't properly cleaned some
residue is left on the surface
I will be giving a paper on the Perfactory system at the TCT Conference 2003
in Birmingham
We have a machine here at the University of Northumbria at Newcastle
Our experience have been very positive (except for a poor batch of resin,
new resin to be released soon with smaller shrinkage co-eff) the first part
produced was within 0.1 mm for a diameter.

I received a sample InVision part and put an image on this page:
http://www.georgehart.com/rp/rp.html
It is the third one down. The stl file is there too if you like. I can
send you a higher-res image of the part if you want.
I love the part for my purposes (as a mathematical model) but don't have
a high-res viper part to compare to. The material has a slightly waxy
feel compared to stl parts I have. I was told that this is due to the
wax support material getting mixed into the material.
I would love to have one of these machines.
