3D printing and CNC machining are common production processes in the field of precision machining. There are similarities and differences between the two. For example, CNC machining is suitable for mass production. It can create many products in less time, and it takes several hours for 3D printing to create a product. Compared with 3D printing, what advantages does CNC machining have? As a company that provides Aluminium CNC Milling Machining Service, we believe the following are the main points:
First, surface treatment advantages
CNC machines offer better surface finish than 3D printing because the material does not deform during processing. Rigid materials and cutting action keep the product together and there are fewer opportunities for errors or distortions. The surface finish of 3D printing is poor. The material is bent, twisted or twisted because the material is layered to heat the plastic.
Second, the prototype integrity has been improved
CNC machine tools do not heat the material and modify it. Compared to 3D printers, materials remain stronger and have better structural integrity, and 3D printers must heat materials to build the desired product. 3D printers may also need to add foreign matter to the mixture to make a prototype, while CNC machines do not.
