Difficulty: parts development takes a long time, from development to testing, many parts need to be made, which takes a long time and costs a lot.

The use of 3D printing can achieve customized production, printing complex structure, function complex parts. When there is a problem in the part test, the r&d staff can modify the relevant documents and print them again through the computer, which can overcome the disadvantages caused by the use of CNC machine tools or manual manufacturing in the traditional auto parts research and development mode. Greatly reduces the time required for product transfer design and prototype development, and rapidly modifies the design scheme. Improve production efficiency, ensure stable performance and quality, shorten production cycle, calculate short delivery cycle.

An engine block

European racing teams are using 3D printing technology to improve the engine performance of their cars. A new engine cylinder head was fabricated by SLM selective laser fusion additive manufacturing technology. Significantly improve the surface heat dissipation area of cylinder head, reduce vibration and weight. The result was a 66% reduction in cylinder head weight, from 5,095 grams to 1,755 grams, and a reduction in volume from 1,887 cubic centimeters to 650 cubic centimeters. The surface area of the cylinder head increased from 823 square centimeters to 6,052 square centimeters, mainly through the complex structure brought by the lattice structure, which resulted in more efficient cooling performance, which is crucial to the performance of the car.
