one,
1. Different accuracy
3D printed prototypes are rough and have low accuracy; while CNC-processed prototypes have high accuracy, which can generally reach plus or minus ten wires. The metal prototypes processed by high-speed drilling and tapping centers can be reached in accuracy.
2. Different costs
3D printing processing programming is easier to use than CNC programming, and it is charged by gram.Therefore, lighter weight prototypes can be selected for 3D printing processing, and large and heavy prototypes prefer CNC processing to be more affordable.
Two,
The material processed by CNC is relatively wide, and it can process all kinds of plastics and metals (such as stainless steel, aluminum alloy, etc.), and its stroke is relatively large, at least more than 1 meter, like a gantry machine tool. The plan can even process a plan of two to three meters in one piece. Since the materials used in 3D printing are liquid, the characteristics of the 3D printing prototypes are not as good as the prototypes processed by CNC. In terms of strength, the strength of the 3D printed prototype is relatively poor, and a screw on it will simply cause a crack; in terms of high temperature resistance, the CNC processed PC prototype will not deform at a high temperature of 90 degrees, while the 3D printed prototype It will be deformed at 60 degrees. The CNC prototype is processed directly on the plate, so it has better characteristics in all aspects. The difference between the two is still great.
