There are three differences between CNC machining and 3D printing:
Handboard processing mainly includes CNC machining, 3D printing, copying, rapid tooling, etc. Today, Noble will tell you the difference between CNC machining and 3D printing. First of all, you should know that 3D printing is a kind of additive technology, while CNC processing is a kind of material reduction technology, so they have great differences in materials
1. Differences in processing materials
3D printing materials mainly include liquid resin, nylon powder, metal powder, etc. These three different materials occupy the vast majority of the industrial 3D printing market; The materials used for CNC machining are all plates one by one, and the selection of materials for CNC machining is more than that for 3D printing. General metal and plastic plates can be processed by CNC machining, and the density of forming parts is also better than that for 3D printing.
2. Different processing accuracy
The hand board printed in 3D is rough and has low accuracy; However, the precision of the hand plate processed by CNC is high, which can generally conquer ten threads. The precision of the metal hand plate processed by high-speed drilling and tapping center can be achieved.

Description from product quality:
3D printing products cannot reflect the quality of products. The purpose of 3D printing is to observe in advance whether the size and structure of products are the same as the design concept.
The products processed by CNC can reflect the product quality, which can be directly used as a complete product.
In terms of price:
3D printing is relatively cheap, but CNC processing is much more expensive.

Choose 3D printing or CNC processing, the most important thing is to see what the demand is, and choose reasonably
