Abstract: A three-dimensional (3D) printing apparatus using selective electrochemical deposition is provided. The 3D printing apparatus is used to selectively deposit a metallic material on a substrate using a nozzle for jetting an electrolyte at a predetermined pressure to enhance 3D printing speed of a metallic product stacked on the substrate. The 3D printing apparatus is configured in such a way that a metallic product is 3D-printed as a metallic material is selectively deposited on the substrate while the electrolyte is continuously jetted at a predetermined pressure and, thus, 3D printing speed of a metallic product stacked on the substrate is remarkably increased compared with the case according to the prior art (Korean Publication No. 10-2015-0020356) in which plating is performed only when a meniscus is formed. Accordingly, the 3D printing apparatus is also applied to 3D printing of a bulk type of a metallic product with a comparatively large shape.
