Abstract: Embodiments of additive manufacturing systems are disclosed. In one embodiment, an additive manufacturing system includes an array of multiple electrodes for sequentially depositing material layer-by-layer to form a three-dimensional (3D) part. The system includes a power source to provide electrical power for establishing a welding arc for each electrode. The system includes a drive roll to drive each electrode. The system also includes a controller to operate the system at a first deposition rate to form first resolution contour portions of a layer of the part. The controller also operates the system at a second deposition rate to form second resolution fill portions of the layer of the part. The system provides variable width deposition at the second deposition rate using a variable number of the electrodes. The first deposition rate is lower than the second deposition rate, and the first resolution is higher than the second resolution.

Abstract: Embodiments of the present invention are directed to systems and methods of predicted a welding property for a given welding operation using at least one electrode. Embodiments determine a predicted weld deposit property and compare the predicted property to a desired property to determine whether or not a selected electrode for the given welding operation can achieve the desired weld deposit.

Abstract: A method for three-dimensional printing includes depositing, via a first metal deposition device, first metal on a base along a first path and simultaneously depositing, via a second metal deposition device, second metal on the base along a second path to form a three-dimensional structure. The three-dimensional structure includes the first metal along the first path and the second metal along the second path. A first end of the first path is adjacent to a first end of the second path. The first metal deposition device moves independently from the second metal deposition device.
