Methods and apparatuses for repairing a broken object. A processor retrieves information describing the size and shape of a broken object. A processor retrieves information describing the size and shape of an intact object, wherein the intact object includes a part missing from the broken object. A processor generates a first three-dimensional model of the broken object based, at least in part, on the information describing the size and shape of the broken object. A processor generates a second three-dimensional model of the intact object based, at least in part, on the information describing the size and shape of the intact object. A processor generates a third three-dimensional model based, at least in part, on a difference between the first and second three-dimensional model. A processor sends one or more instructions to a three-dimensional printer to create an object based, at least in part, on the third three-dimensional model.
