A Review of the Recent Developments and Challenges in Wire Arc Additive Manufacturing (WAAM) Process

Abid Shah et al.

Summary: Wire arc additive manufacturing (WAAM) is an emerging technology that has the potential to produce medium-to-large-scale metallic components/structures for various industries. It offers advantages such as shorter lead time, reduced material waste, and cost-effectiveness compared to traditional manufacturing processes. This review paper discusses the critical aspects of the WAAM process, challenges faced, monitoring methods, gases used, and different materials utilized. It also provides an overview of recent developments in depositing copper-based alloys using the WAAM process.

Revisiting the fracture forming limits of bulk forming under biaxial tension

Rui F. Sampaio et al.

Summary: This paper presents a new upset formability test geometry and an analytical expression for characterizing the formability limits of bulk metal forming parts. The authors use a combination of experimentation, analytical modeling, and numerical simulation to study fracture in bulk metal forming parts subject to stress-triaxiality values beyond uniaxial tension, aiming to fill the knowledge gap in this area.

Economic and Environmental Potential of Wire-Arc Additive Manufacturing

Manuel Dias et al.

Summary: This study focuses on the potential application of Wire-Arc Additive Manufacturing (WAAM) in producing metallic customer-oriented parts. The economic viability of WAAM is evaluated using a process-based cost model, and its environmental impact is assessed through life cycle assessment. The results show that WAAM can be economically and environmentally viable, and further development and optimization will enhance its ability to address novel production challenges in a time and cost-effective manner.
