Hmmmm, two thousandths of an inch. Are you saying that all RP equipment
except Sanders is only accurate to that or is this only the Actua?
Of course the Actua (and Z-Corp and other concept modelers) will not
hold tooling tolerances. If we are talking about SLA & LOM, we
consistantly hold 0.25-0.35mm (0.010-0.014 inch) tolerance evben on full
envelope parts. I have many CMM printouts to support that. Maybe the
folks in question just don't know how to dial in their machines?
Let's compare apples to apples. A Sanders was never intended to be a
concept modeler. Maybe their recent marketing has tried to change that
but I think that that is a mistake.
