The influence of process parameters like laser power, deposition velocity, etc. along with the chosen toolpath strategies on the build quality has been discussed in this chapter. It describes the methodology used for identifying key process parameters and their effects on geometrical and mechanical characteristics. The chapter includes detailed analysis of slicing and hatch parameters, fabrication of test geometries, and characterization of build quality. It also covers the fabrication of thin-wall demonstrator components, assessing different toolpath strategies and their influence on final component quality.
