The components used in heavy equipment need to be made of industrial grade materials and durable. The pressure to innovate, improve efficiency and shorten R & D time drives design engineers and plant managers to use 3D printing, because the technology can not only save time and cost greatly, but also produce heavy load components with flexible design and equivalent quality. Using standard foundry industrial materials, processes can be easily integrated into existing manufacturing and foundry processes. In the traditional manufacturing method, the possibility of human error is very high. 3D printing can reduce the probability of human error and the scrap metal ratio.
