A Closer Look at Precision CNC Machining vs. 3D Printing

We are continuing our series on the differences between precision CNC machining and 3D printing.  When it comes to contract manufacturing, prototypes to production manufacturing, small part machining, close tolerance machining or any other machine shop service, it is important to understand the advantages and differences of different process types. Our previous article discussed the 3D printing and precision CNC machining processes themselves as well as the setup of each.  This article will explore two more areas and the defined differences of each.


There are significant limitations as to the materials you can use with 3D printing.  CNC machining, on the otherhand, can accommodate all types of solid materials including metals, wood, composites, plastic, and, as we discussed in a previous article, ice!

Surface Finish

Precision CNC machining allows for just about any type of surface finish for any material being used.  3D printing is somewhat limiting in this aspect.
