I'm using 3shape with a D2000 and an E3 scanner. When I create an order for a custom abutment + crown I design both at the same time, send abutment to implant manufacturer and mill the crown in-house. What ends up happening a lot of the time is the abutment gets grinded modified when we receive it or it won't fit the crown that designed with the abutment. Does anyone know why this might be?
As JMN has pointed out it matters what the settings are. people often don't understand the issues when attempting to mill things within tolerance. especially from two different places. milled pieces from one machine do not equal milled pieces from another machine. thats not how it works in any CNC industry.
the two imes mills i have do not make parts that easily mate.
so i know what i'm talking about here.
please review your design principles, following a thorough review of the settings used for sending files to each manufacturer. best way to find out whats up is to send each place a prism, like a cylinder or cube, and have them mill it and send it back UNTOUCHED, because then you will see if you have parts coming back off-spec.
it is a nightmare right now getting and keeping calibration down for me. the rigours of cutting hard vs soft materials take a toll on your axes. throws things out of whack if you frequently change.
yet another reason to stick to a single material per mill (for dental purposes) but i digress
