Wire arc additive manufacturing employs an electric arc as a heat source and metal as the deposition material. Standard arc welding equipment and readily available filler alloys coupled with a multiaxis robot means a system can be purchased for a little more than $100,000.
As in standard MIG/MAG welding, metal wire is added as the electrode melts in the arc and its droplets form layers on the substrate. Processes with lower heat input, such as controlled short-circuit metal transfer, are preferred given the heat sensitivity of most materials used in additive manufacturing.

Make Metal Parts Faster & Cheaper with EBAM ® Metal 3D Printing Technology 3D Printing has had an undeniable impact on the manufacturing world. Parts made faster, with less material waste, reduced machining time, and shorter time-to-market are just some of the benefits attainable with 3D printing (a.k.a. Additive Manufacturing or Direct Digital Manufacturing).
For GMAW-CV the welder selects the wire feed speed (WFS) on the wire feeder unit and an appropriate voltage on the welding power supply. The internal circuitry of the power supply then supplies an appropriate amount of welding current necessary to maintain a stable arc.
3DMP ® can replace all the types of conventional manufacturing and machining methods for metal parts, such as forming, cutting, joining, coating, milling, turning, etc. Compared to the conventional manufacturing of near-net-shape parts for mechanical finishing, 3DMP ® is definitely the most economically efficient additive manufacturing method with production cost savings in the range of up

Most EPA inspectors used to pay scant attention to welding fumes; these days they warrant much more attention. Regrettably the EPA relies on AP-42, a document that is thorough in some areas but not too detailed in welding processes. This means an overly zealous inspector might rate your facility as emitting more than it really does, forcing you to implement expensive and unnecessary controls
Abstract: This paper presents the benefits and challenges of using a standard robotised laser welding cell for additive manufacturing (AM). Additive manufacturing, sometimes denoted 3D-printing or rapid prototyping, has lately met strong interest in several areas of society, and a variety of technologies and materials have been in focus.
