[QUOTE="BobCDT, post: 84795, member: 3119"] Sorry if I have misled you here. I believe the current state of printing technology does not provide inexpensive printers with adequite accuracy for crown and bridge. I may be a little out of line here (sorry) as i have not tested all of the inexpensive printers available. We have looked at several printers that manufacturers have claimed to be adequitely accurate for our indications. We have not been able to confirm this through our test results. In fact many of these printers have routine inaccuracy of over 100microns. The only printer that we have tested that will work within normal acceptabe tolerances (not necessarily just up to my standards) is the 3D Systems MP 3500. With this printer we are seeing maximum model inaccuracy of about 25 microns. [/QUOTE]
