“…-Path generation: this is an important parameter that affects geometry accuracy, cohesion in the part, residual stresses, and the finishing state [20,63,91]. Path generation needs to handle as much the change in process speed and the transition time at the borders [92]. A specific branch of research is dedicated to the optimisation of tool generation path including studies related to the improvement of the scanning mode [93,94], geometry slicing strategies [95,96], optimal material deposition [97,98], multi-directional AM [99], tool path anticipation procedures [100].…”
