CNC Machining and 3D printing: the manufacturing game between subtractive and additive manufacturing

Table of Contents

Do you know difference of cnc machining and 3D printing ? and do you also know the process difference ?Now reading this passage and you will know better about them.

CNC Machining and 3D printing represent two core manufacturing philosophies. CNC Machining is “subtractive manufacturing”, which precisely “carves” parts from a whole piece of material through cutting. It is skilled in processing high-strength materials such as metals, and has high precision and excellent performance in finished products. It is the cornerstone of traditional heavy industry.

3D printing is “additive manufacturing”, which constructs objects by stacking materials layer by layer. It does not require complex molds and can easily achieve extremely complex internal structures and lightweight designs, greatly accelerating product development and prototype manufacturing.

The two are not simply substitutes, but complement each other. 3D printing excels in rapid prototyping and complex structures, while CNC

machining excels in producing large quantities and high-strength final parts. In modern manufacturing, they are collectively forming a complete solution from design to finished product, driving the innovation of intelligent manufacturing.
