The emergence of 3D printing prototypes will have any impact on CNC machining

both 3D printing and CNC are tools for prototyping. 3D printing is a hot technology in recent years. CNC machining is a more traditional prototype processing technology. So will the emergence of 3D printing prototypes have an impact on traditional CNC machining? The answer is yes. Let's take a look at the comparison of these two processing methods.

1. Comparison of working principles:

is a way to create materials layer by layer. Similar to building a wall with bricks. Just this'Brick'It may be solid or liquid. CNC machining is to do subtraction on the material, using the CNC machining center to remove the excess parts of the material, so as to get the shape on the drawing.

2. Comparison of the materials used:

3D printing prototype: extremely high material utilization, how much to use, no waste;

CNC machining: The utilization rate is not high, the waste is ABS plate, and the cost is relatively high;

3. Process comparison:

3D printing prototype: 3D printing can process various complex surfaces and special-shaped structures, and complete one-time processing;

CNC machining: complex parts need to be made multiple times, and the workload of splitting programming is large, and the amount of manual assembly in the later stage is relatively large;

It seems that CNC machining is basically defeated in these aspects, then CNC machining is really useless at all. In fact, CNC machining has an advantage in processing large prototypes, while 3d printing can only process small prototypes due to limited travel, in addition, CNC machining can also have a wide range of materials. In addition to plastic prototypes, metal prototypes can also be processed, and some can even process Wood.

so the emergence of 3d printing prototypes will affect CNC machining, however, CNC machining cannot be completely replaced.
