Abstract
An apparatus and device for building an article by additive manufacturing or 3-D printing. The method includes feeding a supply of particulate slurry to and through a nozzle, such as including an integrated pump, to form a plurality of beads and layers of the slurry on a deposition surface, and ultimately forming a desirable article from the layers of deposited material. The liquid phase of the slurry is desirably removed by heat, and the deposited layers can be sintered or otherwise fused as needed.
