Systems and methods are described herein for fitting of a dental analog. In an embodiment, a test block may be printed that includes a number of analog pockets of different sizes. A dental analog may be tested within the analog pockets to determine which analog pocket provides the best fit. Once the best fitting analog pocket is identified, a corresponding library file describing the geometry of that analog pocket is identified, and a dental prototype model may be 3D-printed using analog pocket geometry based on the analog library file. By printing using common printing parameters and the identified analog library file, the resulting printed dental prototype provides the same fit as the analog pocket identified within the test block. This use of a test block reduces or eliminates the need for iterative cycles of printing and testing multiple printed dental prototypes.
