Paragraph starter
The economic viability of manufacturing processes is a critical consideration in design. Research by Zhai (2012) highlights that Wire Arc Additive Manufacturing (WAAM) can be more cost-effective than traditional CNC machining, particularly for components with high buy-to-fly ratios, due to significant material savings. This suggests that for designs requiring substantial material removal, exploring WAAM could lead to considerable cost reductions.
