[0002] Electric arc additive manufacturing technology (DED-ARC) is an advanced digital manufacturing technology that uses electric arc or plasma arc as a heat source to melt metal wire. Under the control of a program or software, it follows the principle of layer-by-layer cladding and manufactures three-dimensional metal blanks that are close to the product shape and size requirements from wire-surface-body based on a three-dimensional digital model.
