3d object parts and cage fabrication

An apparatus comprising:

• a processor;
• and
• a memory on which is stored machine readable instructions that when executed by the processor are to cause the processor to:
• access instructions to fabricate parts of an object, wherein the parts are to be assembled together to form the object;
• determine locations at which the parts are to be fabricated with respect to each other in a build envelope, wherein the determined locations correspond to positions of the parts with respect to each other in the object after assembly of the parts;
• and
• form, via three-dimensional (3D) fabrication, the parts at the determined locations.

A computer-implemented method comprising:

• accessing, by a processor, data pertaining to fabrication of items of an object, wherein the items are to be joined together to form the object;
• determining, by the processor, locations at which the items are to be fabricated with respect to each other in a build envelope, wherein the locations correspond to relative positions of the items with respect to each other in the joined object;
• modelling, by the processor, a cage to surround the items, wherein the data pertaining to fabrication of the items do not include data pertaining to fabrication of the cage;
• and
• controlling, by the processor, fabrication components to fabricate the items at the determined locations and the cage around the items.
