Multi-axis Wire Arc Additive Manufacturing Using Optimized Fabrication Sequence: Exploring challenges in implementation and experimental validation of fabrication sequence optimization for distortion minimization in multi-axis wire arc additive manufacturing

Wire arc additive manufacturing (WAAM) is attributed to higher material deposition rates and medium to large build volumes. Integration of multi-axis (more than three) material deposition kinematics in WAAM can bring a paradigm shift in the metal additive manufacturing industry. The material build-up mechanism employing directed energy...

Predicting Thermal History, Microstructure and Hardness of Wire Arc Additive Manufactured Parts

Wire Arc Additive Manufacturing (WAAM) is a manufacturing technique with the ability to produce large metal parts with relatively complex geometrical shapes. One obstacle limiting full exploitation of WAAM in the industry is uncertainty on the mechanical properties of manufactured parts. Mechanical properties are strongly influenced by the...
