What is 3D printing CNC?

If you’re a maker, tinkerer, or 3D printing hobbyist, you’ve likely heard the term “CNC” used quite often. It stands for computer numerical control, which is a process used to control many types of traditional machining tools as well as newer additive manufacturing machines like 3D printers.

Is CNC the same as a 3D printer?

They key difference between 3D printing and CNC machining is that 3D printing is a form of additive manufacturing, whilst CNC machining is subtractive. This means CNC machining starts with a block of material (called a blank), and cuts away material to create the finished part.

What is better CNC or 3D printing?

Surface Finish: With the right tools, CNC machines are capable of producing much smoother surfaces than 3D printers. 3D printers are capable of producing parts for fit and finish, but for parts that require exceptional smoothness for mating with other precision components, CNC machining may be preferable.

Are printers CNC machines?

In addition to these tools, exciting new machines, such as 3D printers and fabrication and assembly robots, also utilize this technology. 3D printers are technically examples of CNC machines.

Can 3D printed parts be machined?

Printed parts can also be machined in order to achieve dimensions with critical tolerances or required surface qualities, or even to mill threads. Jigs and fixtures as well as clamping and positioning tools made by 3D printing facilitate working with CNC machines.
