Differences in materials between CNC machining and 3D Priniting

First of all, 3D printing is an additive technology, and CNC machining is a subtractive technology, so they are very different in terms of materials. The main materials for 3D printing include liquid resin (SLA), nylon powder (SLS), metal powder (SLM), gypsum powder (full-color printing), sandstone powder (full-color printing), wire (DFM), and sheet (LOM) etc. Liquid resin, nylon powder and metal powder occupy the vast majority of the industrial 3D printing market.

The materials used for CNC machining are all pieces of plates, which are plate-shaped materials. By measuring the length, width and height + loss of the parts, plates of corresponding sizes are cut for processing. CNC machining materials have more choices than 3D printing. General hardware and plastic sheets can be CNC machined, and the density of molded parts is better than that of 3D printing.
