Wire + Arc Additive Manufacturing

Wire + Arc Additive Manufacturing(WAAM) is a process which can create parts made from strong materials, such as aluminum and steel. The wire based method builds a part in the vertical direction by depositing single layers of material in an additive process. This process gives a high level of design freedom, reducing part weight and complexity.

They solve tens of billions of equations quickly in inexpensive computers.

Wire and Arc Additive Manufacturing - TWI

First patented in 1920, WAAM is probably the oldest, outwardly simplest, but least talked about of the range of additive manufacturing (AM) processes. Using wire as feedstock, the basic process has been used to perform local repairs on damaged or worn components, and to manufacture round components and pressure vessels for decades.
