How accurate can the parts be made on a good 3d printer? I just finished this fabrication job at a Lampworks metal shop and the pieces that I needed to fit on a lamp in brass angle was too big by .030
I had to sand down all the pieces after they were molded.

When I looked into buying a 3D printer, the sale's guy said + or - .005. But my sample parts were not even with in that range, roundness was less than expected and they all had small deformities. I was not impressed. Parts where made on a Stratasys Design Series printer out of ABS plus.

Tolerances much tighter than .005 can be held. At work, we have been using SLA since the late 1980s for making patterns for investment castings, and hold tolerances of much less than .005 all day, every day. And this is on pattern segments as much as 24" square.
Then again, our machines cost 200,000 and we do alot of calibration on them.
