The 3DMP additive manu-facturing technology is based on well proven electric arc welding and uses wire as original material. The final part is formed by applying welding layer over welding layer. Compared to other additive manufacturing technologies, which are based on powder as original material, 3DMP is less expensive.

2018/9/21· Abstract For wire and arc additive manufacturing (WAAM) technology, the instable formation and the quality of the weld bead is still a problem. In welding technology, the weave bead welding can improve welding efficiency and welding quality. Besides, the weaving
In wire-feed AM, a metal wire is used as supply material to build components – typically large ones of moderate complexity. Depending on the energy source used for deposition, wire-feed AM can be classified into three groups: wire and laser additive manufacturing (WLAM), electron beam freeform fabriion (EBF3) and wire and arc additive manufacturing (WAAM) [1, 2].
Arc welding and wire arc additive manufacturing or WAAM techniques are attracting interest from the manufacturing industry because of their potential to fabrie large metal components with low cost and short production lead time. This process exists alongside
2019/2/14· The welding system 100 contains a welding power source 109 which is coupled to both a welding torch 111 (having a contact tip assely—not shown) and a wire feeder 105. The power source 109 can be any known type of welding power source capable of delivery the current and welding waveforms described herein, for example, pulse spray, STT and/or short arc type welding waveforms.

Wire-laser additive manufacturing (WLAM) is a technology in which 3D components are built by continuously feeding a wire into a melt pool generated by a laser beam. This process enables costs and time saving in comparison with traditional methods, which
Electron-beam additive manufacturing, or electron-beam melting (EBM) is a type of additive manufacturing, or 3D printing, for metal parts. The raw material (metal powder or wire) is placed under a vacuum and fused together from heating by an electron beam. This technique is distinct from selective laser sintering as the raw material fuses
In wire-feed AM, a metal wire is used as supply material instead of metal powder. Depending on the energy source used for metal deposition, wire-feed AM can be classified into three groups, namely: laser-based, arc welding-based and electron beam-based [29
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.
Beginners’ welding course instructors will start by telling you about wire. Both the MIG welding process and the flux core process use what’s called a wire welding machine. A wire welder differs from a process like stick welding because the electrode, the metal that melts to make the weld bead, comes on a roll of wire instead of a long steel rod.
