The assignee for this patent application is Relativity Space Inc. (Long Beach, California, United States). Reporters obtained the following quote from the background information supplied by the inventors: “Wire arc additive manufacturing (WAAM) is a production process used to 3D print and/or repair metal parts. WAAM is a process where a metal wire is provided from a tip of a welding robot while heat energy is applied to the metal wire and the heat energy melts the wire to allow it to be layered in the desired shape of the component being manufactured. Print orientation for WAAM is ordinarily vertical, such that each layer is stacked one on another in a height-wise direction (e.g., in a direction from the floor toward the ceiling). Vertical orientations are commonly assumed to be the only viable printing configuration for WAAM, in part, because gravity generally acts on each point of a layer uniformly.”
