Differences and Similarities Between 3D Printing and CNC Machining


3D printing

As we know it is a additive manufacturing, creates objects by printing layer by layer. It can be applied to a variety of materials, such as resin, ABS, PA and so on.

CNC Machining

Also as we know it is a subtractive manufacturing and it is quite different from 3D printing. The process usually starts with a solid block of material, and then uses various tools to remove the material and shape the part. CNC machining materials include plastic and metal. It is currently one of the most popular and mature manufacturing methods, suitable for small and Low-Volume Manufacturing.





What are the differences between 3D printing and CNC Machining?


The main difference between 3D printing and CNC is that they work differently. 3D printing is an additive technology, while CNC is a subtractive technology. As we all know, 3D printing is easier to use than CNC machining. When the file is ready, you only need to select the part orientation, fill and support as needed. Then start to print. There is no need for a supervisor to supervise the whole process of printing. However, CNC is a labor-intensive process. It requires both skilled operators and different tools. It also requires complicated post-processing. 


What are the similarities between 3D printing and CNC Machining? 

Both 3D printing and CNC involve 3D files and can also produce robust and fully functional parts. In addition, the finished product after 3D printing may require a little machining to meet the standard of use when it is post-processed.
