3D printing and CNC machining are relatively common production processes in the field of precision machining, and both have similarities and differences.

CNC machining is suitable for mass production. It can create many products in less time than 3D printing takes hours to create one product. ​prototype production ，What are the advantages of CNC machining over 3D printing?

CNC machines provide a better surface finish than 3D printing because the material does not deform during processing. The rigid material and cutting action hold the product together, reducing the chance of error or deformation. The surface finish of 3D printing is worse than cnc. Because the material is layered heated plastic.
