[QUOTE="deadhead, post: 307249, member: 19095"] we used to have this issue on our bridges too. Tried everything from stabilizer bars and editing our sintering times. nothing worked, then we milled out of wax and still had an issue with fit. bridge fit perfect on each prep individual so we looked at design and found our problem. The designer was not setting the path of insertion right so when it was generating the NC file it was not compensating for under cuts of a bridge so our bridges would not fit. once we got our designer on the right page about path of insertion our fits have been perfect. We mill full arch bridges to 3 unit bridges with no stabilizer bar and havent had a fit issue since we ressolved our issue. hope this helps. When in doubt go back to design and check all parameters and path cause now a days if you use high end ZR stabilizer bars are not necessary. if you have a fit issue i would definately check your path and design parameters first before messing with sintering cycles and bars [/QUOTE]
