Computational design for the wire and arc additive manufacturing process

Abstract

The world has seen industrial revolutions with advancements in manufacturing technologies. The advancements in Additive Manufacturing (AM) technologies will bring another revolution sooner rather than later. Nowadays, the Wire and Arc Additive Manufacturing (WAAM) process is already used to manufacture large-scale structures such as ship propellers, pedestrian bridges, aircraft components, and heavy-lifting structures. These structures are critical load-bearing structures during operations. WAAM has high material deposition rate which is unique within the entirety of metal AM processes. Moreover,WAAMreduces lead time and material waste compared to conventional manufacturing processes such as milling and casting.
