Do 3D Printing And CNC Coexist or Compete With Each Other?

2020-11-13

With the development of 3D printing, whether the traditional way of reducing material manufacturing such as CNC machine tools will be replaced has become a hot topic among all walks of life. Generally speaking, CNC machine tools need to be pre-programmed to shape objects through constant cutting. The working principle of 3D printers is similar to that of CNC machines, also based on computer instructions, the difference is that 3D printers manufacture products by accumulating the 3D Printing material layer by layer. Therefore, 3D printing is also called "additive manufacturing".

The significant difference between 3D printing and traditional manufacturing lies in the process of molding a product. In traditional manufacturing, the entire manufacturing process generally involves molding, cutting, casting or forging and component assembly. 3D printing eliminates the complex processes and molds, it is one-off molding. As a result, 3D printing can overcome some of the designs that cannot be reached in traditional manufacturing to produce more complex structures.

It is understood that 3D printing technology has been applied in China current industrial parts manufacturing, but it has not yet been widely used in industry. The process and equipment, as well as in the medical, aerospace and other fields of application are to be further developed. In the current situation, 3D printing technology does not have the conditions to replace the traditional manufacturing industry. In mass manufacturing and other aspects, machine tool manufacturing for the embodiment of the efficient low-cost traditional material reduction manufacturing method is better.

With the emphasis on metal augmentation, more and more equipment manufacturers in the traditional machine tool manufacturing field have entered the additive manufacturing field. The long-term coexistence of subtractive manufacturing and additive manufacturing methods is an identifiable trend. However, this may change in the future. In any case, it is expected that the methods that enable fine, automated, and efficient manufacturing of products will be used in a variety of applications.
