1. A method comprising:
- providing a first size of a build volume for a three-dimensional printer, the first size including physical dimensions of the build volume;
providing an object model having a second size greater than the first size of the build volume;
separating the object model into a plurality of sub-objects each smaller than the first size of the build volume according to one or more criteria, wherein at least a portion of the plurality of sub-objects are created such that two or more of the plurality of sub-objects can fit collectively into the build volume, with each of the two or more of the plurality of sub-objects in a stable orientation abutting a build platform within the build volume, for combining the two or more of the plurality of sub-objects for fabrication by the three-dimensional printer in a single print;
adding assembly features to the plurality of sub-objects to facilitate a joining of each one of the plurality of sub-objects to at least one other one of the plurality of sub-objects;
adding an identifier to a mating surface of each one of the plurality of sub-objects, the identifier uniquely identifying each sub object to distinguish sub-objects from one another to assist in assembly thereof; and
fabricating a physical instance of each one of the plurality of sub-objects with a three-dimensional printer, thereby providing a plurality of physical sub-objects.

17. A computer program product comprising non-transitory computer executable code embodied in a computer readable medium that, when executing on one or more computing devices, performs the steps of:
-
providing a first size of a build volume for a three-dimensional printer, the first size including physical dimensions of the build volume; providing an object model having a second size greater than the size of the build volume; separating the object model into a plurality of sub-objects each smaller than the first size of the build volume according to one or more criteria, wherein at least a portion of the plurality of sub-objects are created such that two or more of the plurality of sub-objects can fit collectively into the build volume, with each of the two or more of the plurality of sub-objects in a stable orientation abutting a build platform within the build volume, for combining the two or more of the plurality of sub-objects for fabrication by the three-dimensional printer in a single print; adding assembly features to the plurality of sub-objects to facilitate a joining of each one of the plurality of sub-objects to at least one other one of the plurality of sub-objects; adding an identifier to a mating surface of each one of the plurality of sub-objects, the identifier uniquely identifying each sub object to distinguish sub-objects from one another to assist in assembly thereof; and transmitting the plurality of sub-objects to a three-dimensional printer for fabrication of a corresponding plurality of physical sub-objects. - View Dependent Claims (18, 20)
