Laser Wire Additive Manufacturing is a 3D printing method that enables to manufacture samples with complex geometries, while having a high flexibility due to the Direct Energy Deposition of the feedstock. This process can be used for different feedstock materials like duplex stainless steels. The aim of the study was to explain the relationship between the process monitoring signals, with the process stability features. This means finding a relationship between process parameters, such as electrical conductance and Line Energy with features like defect ratio of the manufactured parts. To obtain the results, data that was obtained from previous manufactured samples was examined, such as, process parameters, monitoring signals and video recordings from a coaxial camera. Also, the conductance signals were analysed using Fast Fourier Transform and Image Analysis, and the Line Energy was as well calculated. The results showed a direct relationship between the Line Energy, conductance signals and the defect ratio of the samples, where higher Line Energy input and stable conductance signals, lead to lower defect ratio
