      First of all, what is injection molding. It is a traditional industrial manufacturing technology. The principle is to melt the material and inject it into various mold cavities and finally obtain the required part contour through cooling and solidification. This technology is also Rapid prototyping technology. Its advantages are: fast molding speed, mass production, disadvantages: low dimensional accuracy, low surface finish. In the injection molding process, fillers can be used to change the hardness and strength.


      The working principle of 3D printing is to make slices through computer modeling, and then connect to the 3D printer to stack layer by layer to form the final shape. Its advantages are: fast forming speed, no need to add fixtures compared to CNC machining, high surface finish, and dimensional accuracy Controllable. In 3D printing, you can test and process it after confirming that it is correct. This process can effectively save time and money, and it can also improve the design of the product. Compared with traditional CNC processing, 3D printing can avoid material waste, reduce waste, and reduce production costs.
