According to foreign media reports, if 3D printing technology is used for tooling and the application of 3D printing technology is no longer limited to the production of prototype parts, the automotive industry will save billions of dollars in product development. .
Lonnie Love, corporate research director and project leader of OakRidge National Laboratory, attended the management of Centerfor Automotive Research on July 31 in Traverse City, Michigan. Briefing seminar (ManagementBriefingSeminars). He said at the meeting that 3D printing tooling is promising, and its results have already begun to appear.
Engineers and researchers at Oak Ridge National Laboratory in Tennessee have produced a tooling that can be used to make automotive hoods. 3D printing relies on Big Area Additive Manufacturing (BAAM) technology. In 2014, Oak Ridge National Laboratory and Cincinnati, LocalMotors and other partners adopted BAAM technology. It took only a few days to manufacture a 3D printing vehicle, and then optimized the process, and created a thank-you with 3D printing technology. Erbe Cobra sports car.
Love said: "Printing a vehicle is a multi-million dollar market, and printing tooling is a multi-billion dollar market." The automotive industry spends billions of dollars a year on tooling, usually requiring steel molds. Or dies, and the above-mentioned molds are usually time consuming, and the cost of acquisition and maintenance are also quite high. Love said that 3D is a good solution, and using this technology will shorten the production time of molds and stampers.
The Oak Ridge National Laboratory has been a compression mold for Ford's producers and is working with the filmmaker DiversifiedTooling Group on additive tooling.
Love said: "The company is trying to achieve this goal in a few days, without spending weeks or months plus hundreds of thousands of dollars in money. The company is undergoing major changes in the moment of pivotal time in the US manufacturing industry. The company is very optimistic about the prospects of 3D printing tooling, the market for additive manufacturing will become very large, the growth rate will be very fast, and the price will become relatively low."
The study focused on plastic and metal additive manufacturing, while 3D printed parts required finishing operations on the surface, but Love said it could be machined or coated to make the surface smoother and shiny.
