A method of producing a variable data design file for use in production of personalized copies of a reference 3D object may include receiving a plurality of fixed structural parameters for a reference object and receiving information for creation of a plurality of variable structural parameters corresponding to variable data regions on the reference 3D object. The method may include using the plurality of fixed structural parameters to develop an instruction set configured to cause a 3D printing device to form a 3D object that exhibits the plurality of fixed structural parameters; and including, in the instruction set, instructions for creating the plurality of variable structural parameters based on the received information that will cause the 3D printing device to render at least one of the plurality of variable data regions in the 3D object, wherein the variable data region differs from a corresponding region of the reference 3D object.
