Traditional component manufacturing involves creating molds, casting and forging, then cutting and polishing to make parts, which generates significant scrap and is cost-inefficient. Complex shapes are often impossible to manufacture using conventional methods. However, 3D printing has precise manufacturing processes and high shape freedom making any shape possible. It can be manufactured based on design data, providing advantages in lead time and minimizing cutting processes, reducing material waste and enabling lightweighting. It also enables precise local repairs for components that were previously impossible to repair with conventional welding methods.
