      With the continuous advancement of manufacturing technology, additive manufacturing, commonly known as 3D printing, and traditional manufacturing processes like numerical control machining (CNC) and reduced-material manufacturing are working together to promote the development of manufacturing. Although 3D printing cannot wholly replace CNC machining, it affects traditional manufacturing methods in several ways.
