Abstract
A metal fused, deposition printer, that uses the thixotropic (or other) properties of a metal (or alloy) to control the viscosity of the material being deposited. In the invention presented in this patent, the viscosity of the metal is controlled by shearing it before, during, or after the deposition process. Since thixotropic (or other) properties allow for the control of the viscosity separately from the temperature, the taught invention allows for precise control of the temperature differential between the layer being deposited, and the substrate layer.
