With the wide application of 3D printing technology, a frequently question being asked is if 3D printing better than CNC machining?
Well, the answer is "it depends".
CNC machining is one of the most common manufacturing technologies.
It offers excellent high accuracy and a wide range of materials, it tends to be a labor-intensive process.
The operator will have to manually set up the workpiece in the machine, keeping all these factors in mind, and knowing whether the component will be ready after machining.
All of these factors will affect the quality and the working time.
CNC machining offers greater dimensional accuracy and producing better mechanical properties in all three dimensions.
However, CNC machining usually comes with a higher price tag, especially with smaller volumes of parts.
3D printing builds parts one layer at a time, this process doesn't require special tooling or fixtures, so the initial setup cost is minimal compared to CNC machining.
When traditional methods are not able to produce the part efficiently or cost-effectively, 3D printing is a best choice.
When you create a new design and are not sure about the structure, 3D printing is the most cost-effective way to do the prototype.
In general, each process has evolved to meet different demands - so it's important to know which process will best suit your needs.
