Because the shape of most auto lamps is irregular and surface is complex, it is difficult to make the mold. With SLA technology, it could make product sample accurately and rapidly, which provides a good reference for CAD mold design and CAM mold design.at the same time, with SLA technology, it could also produce lamps molds rapidly and accurately through investment casting process by integrate with vacuum injection method.

As the price of 3D printer goes down and the industry chain is mature (designer, manufacturer, supplier and integrator and customer) , 3D printing technology would change the market rule in auto market.

As the 3D printer technology is mater and widely applied, the auto customer could print out new product model of new design at any time and in any place, so it could provide new idea and new design materials source for design department of auto manufacturers, moreover, the new product designed by Crowd souring could be rich in form and dynamic

The customer could choose combined auto parts as they like from the specific market, mobile phone and network, such as auto pumpers, rear-view mirrors, headlamps, instrument board, steering wheel and other inner and outer side decorative parts. After the design demands from customer are confirmed by auto dealer, the 3D printing service dealer could make these combined auto parts and then the customer could get the customized autos.

The auto 4S stores or the owners of auto could print auto parts and maintenance tools by using 3d printer, especially; the 3D scanner is used to scan prototype, and then modeling by using reverse design software, finally, the copy of tools could be printed by 3D printer.
