Modeled in sculptris
and truespace 5
test printed 2 shells 0 infill
some top of model holes (typical on rounded top things)
I ran a big print using the accelerated settings.
2 shells 0% infill
adequate for my purposes
as with many of my models,
I do a follow up using ABS / acetone goop to fill in
gaps and small holes.
if you want to play with using infill and other settings you might minimize the holes.
I prefer the 0% infill and multiple shells.
My experience since switching to using the 0% infill
is far less issues with separation cracks, lighter objects
(therefore using less plastic) and if i go to 3 shells
the objects are really solid.
