3D Printing x CNC machining

3D printing and CNC machining are two of the most common prototyping or manufacturing methods used in the twenty-first century. Both methods can physically create models using digital design files such as CAD.

If you’re thinking of using either of these methods, we would strongly advise you source an experienced CAD modeller, first.

3D Printing

3D printing works by adding material, layer by layer to build a structure. You can use a range of materials, such as; stainless steel, aluminium, a range of plastics and even carbon fibre.

Benefits of 3D Printing

Complex products can be produced rapidly.

Prototypes can be produced at a low cost.

Speeds up product development journey, allowing you to get to the point of large scale manufacturing, quicker.

CNC Machining

Unlike 3D printing, CNC machining is a process which involves the subtraction of materials. When you are CNC milling, you can use various materials, including stainless steel, aluminium, titanium, brass and a range of plastics.

How does CNC Machining work?

You start off with a block of material, and the CNC machine removes material until your design is revealed. It’s kind of like a sculptor chipping away at a block of stone, to then unveil a sculpture.

Benefits of CNC Machining

CNC stands for computer numerical control and the benefits of CNC machining or milling include:

Accuracy: Its measurements are recorded at a thousandth of an inch.
Faster run time than older traditional methods.
Multi purposeful: CNC machines use a range of tools meaning that they can apply different manufacturing techniques in one session
Can be used for large scale production.

CNC machining is such a precise and reliable manufacturing method that it is even responsible for producing some of the everyday-items you’ll see, such as parts in your car or the metal pieces within the internal workings of your smartphone.
