The ModuleWorks Wire Arc Additive Manufacturing (WAAM) calculation core incorporates a toolpath planning algorithm epecially suited for manufacturing complex geometries and customized structures. The various process parameters such as welding speed, current, voltage and wire feed speed are defined in the Post Processing Framework (PPF) to achieve a specific geometry wall width/height (multi-layer) with maximum deposition efficiency. This calculation core facilitates the manufacturing of near net shape geometries for varying welding processes like Cold Metal Transfer (CMT) and synchrofeed welding.
