Traditional casting process is that design mold according to the drawings, and then making mold etc. Too many procedures required to complete casting parts.
The 3D printing technology is virtual manufacturing software for casting process design, direct 3D print out casting hollow cavity, and then pouring. So, casting time can be reduced a half at least. Of course the income will be increased. Moreover, for the complicate structure and small casting products, when we use conventional casting process, the rate of finished product is only about 40% -50%.
If we adopt 3D printing technology, the final rate of finished products is above 90%.New technology let us understand that there isn't decline field, and not decline business. At this downturn moment of whole casting industry,3D printing technology point out a bright direction for traditional industrial enterprises.
