Wire arc additive manufacturing of porous metal using welding pore defects

Materials & Design, 2023
A novel wire arc additive manufacturing process is proposed to produce porous metal (PM). The innovation is to convert harmful welding pore defects into a beneficial structure of PM, and then the PM parts can be additive manufactured layer by layer.

A Review of Wire Arc Additive Manufacturing

International Journal of Scientific Research in Modern Science and Technology
Wire Arc Additive Manufacturing (WAAM) is a metal additive manufacturing (AM) process based on the technique of Directed Energy Deposition (DED), which uses an electric arc to melt wire feedstock for the layer-by-layer fabrication of large, near-net-shape metallic components of complex geometries.

On wire and arc additive manufacture of aluminium.

, 2020
Wire and arc additive manufacture (WAAM) is a process in which an arc is used to melt and deposit beads of feedstock wire layer by layer onto a substrate and then subsequent layers to create near-net shape components. WAAM has the potential to reduce costs and material waste, as well as shorten lead-time, compared to conventional manufacturing methods.
