How exactly is 3D printing revolutionizing manufacturing?

The usual process of traditional casting is to use easily moldable materials to create a master mold that has a similar appearance to the product. Then, in the mother of the mold is covered with a certain viscosity of the sand, with the machine vibration and then take out the mother of the mold, the sand will naturally form the mother of the mold is also the shape of the product, such a casting mold is called the sand mold. Finally, the molten metal is poured into the sand mold through the reserved pouring holes, and after cooling, the surrounding sand mold is removed and then mechanically processed to a certain extent.

With 3D printing technology, it is easy to adjust the design and generate the master mold in real time. The master mold in the traditional process doesn't need to be machined purposely anymore, which greatly saves the time and efficiency of making the master mold. It is like replacing engraving with movable type printing, no need to discard the whole plate because of a plate-making error, and adjustments can be made easily at any time. At the same time, the master mold generated by 3D printing can be selected according to the specific circumstances of different materials, for the durability of the occasion requires high metal materials, for the cost of the occasion requires high resin materials, in either case there is no traditional wood mold sensitive to temperature and humidity, easy to deformation of the low life expectancy of the defects. Even the production of the mother mold process can be skipped, the use of 3D printing technology can directly generate casting sand, of course, this time the raw materials used are ceramics that can withstand high temperatures. This 3D printing sand mold can maximize the original form of the casting, greatly improving the accuracy and yield of the finished product.

We must note that 3D printing can flourish in the context of the times, that is, the steady progress of computer computing power and related software to enhance the function. In the 30 years since the birth of 3D printing, there have been no revolutionary breakthroughs in materials and electromechanical fields, but the computing power of computers has increased thousands of times over, ultimately revolutionizing our lives and production patterns and contributing greatly to the development of 3D printing.
