Porsche announces that it will output and supply the old "old car" parts with 3D printers

byJean-Jacques MARCHAND

Spare parts of "old car" which passed decades after the end of production may become difficult to obtain with time, in the worst case the car itself may not function due to the lack of small parts. However, in order to recreate old parts newly, it is necessary to rebuild including the special tools for production, and if parts with high demand are still needed, it is clearly inefficient if only a small amount is needed. Therefore, Porsche announced that it will output spare parts of the old car which needs only a few with the 3D printer. Spare parts made by 3D printers are almost same as the original, both apparently and functionally.

Porsche Classic supplies classic parts from a 3D printer

For example, a super car that appeared in 1986Porsche 959"Clutch lever" used in the clutch of the clutch has already been abolished. This clutch lever made by gray cast iron is very high quality, but demand is extremely small because only 292 cars are made. Therefore, selective laser melting (SLM /Laser layered modeling method) Was adopted, and the method of completing a three-dimensional component was adopted by repeating the method of "melting by irradiating a layer of metal powder of 0.1 mm or less with a laser". When I conducted a test with a car equipped with a lever actually outputted with a 3D printer, it was confirmed that the function and quality are comparable. For plastic parts, "Selective Laser Sintering (SLS /Powder sintering laminate molding method) "Has been outputted.

After repeating such a test, Porsche succeeded in outputting eight parts in addition to the lever of the clutch using a 3D printer. Each part meets the same or higher quality standards as the original, and it is confirmed that it fits the car by the test.

In Porsche, in addition to the model of the 1980sPorsche 356We are also promoting this approach for classic cars that were born in the 1950s. In the future, further 20 parts will be developed and improved with 3D printers, which shows the intention to reduce parts costs and provide parts when demand is available.
