Abstract
Systems and methods in accordance with embodiments of the invention implement additive manufacturing processes whereby the constituent material of an object to be fabricated is manipulated prior to, or during, the respective deposition process such that different portions of the deposited constituent material can be made to possess different material properties. In one embodiment, an additive manufacturing apparatus includes: a nozzle configured to accommodate the extrusion of a constituent material through it and deposit the constituent material onto a surface in accordance with an additive manufacturing process to build up an object to be fabricated; and a subassembly configured to manipulate the material properties of some portion of the constituent material such that different portions of the deposited constituent material can be made to possess different material properties; where the subassembly is configured to begin said manipulation prior to, or concurrently with, its deposition onto a surface.
