The micron thickness specified by the machine makers would at
first glance seem to be more than adequate. The issue is that they
are generating a voxelated (pixel picture element voxelvolume
element) model of a curve function. It is always going to be an
approximation of the original curve that will result in aliasing
and other artifacts. The artifacts of this process will always be
there. Yes you can make the voxel smaller but there are issues. One
drawback of going for higher resolution is that the build time goes
up geometrically with the increase in resolution. So if you half
the voxel size your build time goes up by a factor of 8 so an eight
hour build now takes 64 hours unless you can also increase the
build speed. Increasing build speed is not so easy to do.
These guys run the printing fairly slowly. They have a lot of
machines, they have them running all the time.
The models are smooth to the touch, straight from the machine.
When I go, I'll ask for wax samples, if I get some I could send you
I was impressed the first time I saw one, and I'm quite fussy too
