How the prototype factory processes the complex prototype model

Now the product will do one or several prototypes in the R & D stage to verify the size, structure, as large as the car, large household appliances such as air conditioners and refrigerators, although most of the prototypes are product models, occasionally they will encounter some more complex prototypes. How can these prototypes be processed?

There are two main ways to process complex prototypes--CNC machining and 3d printing. CNC machining is mainly used to process prototypes with large volume and high machining accuracy. Once the complex prototype is processed, it needs to be disassembled, and all parts of the prototype are Gonged Out through the CNC machining center, and then spliced back. However, in doing so, the strength and other performance of the prototype are not as good as that of the whole processing.

while 3D printing can be processed complex surfaces and special-shaped structures, forming once. In short, in the view of most people, the traditional prototype manufacturing can only be an infinite approximation of the prototype of the product, thus verifying the product, but there will always be errors, and 3D printing can directly output the product. However, 3d printing is charged by weight and is not suitable for printing large prototypes. The turbine prototype in the following figure is printed in 3d. It is small in size and complex in shape. It is very troublesome to do it through CNC, and the time spent is relatively long.

to sum up, large complex prototypes are processed by CNC, while small complex prototypes are made by 3d printing.
