What type of CNC machine is used for 3D cutting?

A CNC milling machine or CNC router is designed specifically for 3D cutting because it operates by moving a cutting tool in multiple axes (typically three or more) to create complex shapes and contours in various materials. The milling head can be adjusted in different directions, allowing for intricate and detailed profiles that are characteristic of 3D cutting.

CNC routers are particularly suitable for working with softer materials like wood, plastics, and composites, while CNC milling machines are more versatile and can handle a wider range of materials, including metals. This ability to achieve precise depth and shape in a three-dimensional context makes them the ideal choice for 3D cutting applications.

In contrast, CNC laser cutters are primarily used for cutting and engraving flat materials and may not be able to produce three-dimensional profiles effectively. CNC plasma cutters focus on cutting metals using a high-temperature plasma arc and are better suited for two-dimensional profiles. Similarly, CNC waterjet cutters are primarily used for cutting through thicker materials and may not provide the fine detail required for 3D shapes compared to milling machines or routers.
