Abstract
A metal fused deposition printer can use the thixotropic properties of a metal (e.g., alloy) to control the viscosity of the material being deposited. The viscosity of the metal can be controlled by shearing the metal before, during, or after the deposition process. Use of the thixotropic properties can allow the viscosity of the metal to be controlled independent of the temperature of the metal. This can allow for more precise control of the temperature differential between the layer being deposited and the substrate layer, for example, such that the temperatures are substantially the same.
