Innovative pistons from a 3D printer for increased power and efficiencyCooperation: Porsche develops new application for 3D printing together with Mahle and Trumpf
Stuttgart/Shanghai. 3D printing technology is already used at
3D printing allows the pistons to be manufactured with a structure that is optimised for the loads acting on the pistons. As a result, the pistons from the advance develop-ment project weigh ten percent less than the forged series production pistons. They also have an integrated and closed cooling duct in the piston crown that could not have been produced by conventional methods. “Thanks to the new, lighter pistons, we can increase the engine speed, lower the temperature load on the pistons and opti-mise combustion,” explains Frank Ickinger from the advance drive development de-partment at
Building up parts layer by layer permits realisation of new and improved de-signs
There are a number of different technologies for 3D printing. All are based on the principle that the components are built up layer by layer without the need to previously manufacture a special tool or mould. Practically any geometric shape can therefore be realised. The printer can be fed with the design data directly from the computer. Addi-tive manufacturing processes are thus ideal for producing structures that have been designed and optimised by means of artificial intelligence (AI). The pistons of the 911 GT2 RS were manufactured from high-purity metal powder using the laser metal fu-sion process (LMF). Here, a laser beam heats and melts the powder surface corre-sponding to the part contour.
