CNC Machining: What is the Difference Between CNC Machining and 3D Printing?

When quoting a prototype project, it is necessary to select an appropriate CNC machining method according to the characteristics of CNC machined parts in order to complete the prototype faster and better. At present, we mainly carry out prototype machining, CNC machining, 3D printing, filming, fast mold, etc. Today we will talk about the difference between CNC machining and 3D printing.



First of all, 3D printing is a material increase technology and CNC machining is a material reduction technology, so they are very different in material.







1. Differences in materials





3D printing materials mainly include liquid resin (SLA), nylon powder (SLS), metal powder (SLM), gypsum powder (full color printing), sandstone powder (full color printing), wire (D FM), plate (LOM), etc. .Liquid resin, nylon powder and metal powder make up the vast majority of the industrial 3D printing market.



The materials used for CNC machining are all pieces of plates, that is, plate-shaped materials. By measuring the length, width, height and loss of CNC machined parts, the corresponding size plates are cut for CNC machining. 3D printing is preferred for CNC machining materials. Generally, metal CNC machining parts and plastic plates can be CNC machined, and the density of molded parts is larger than that of 3D printing.
