Re: .010 slice for sla 500

Bob and Ingrid,

I am curious. Why do you want to build at .010" layers? There is
considerably more finishing to do, and there is theoretical and empirical
evidence to show that the maximum layer thickness for speed is somewhere
close to the Dp which is typically around .005-006". Are you exceeding the
limit of the scanning system at these layer thicknesses?
