With some bucket seats from the 911 and 718 as well as various classic auto parts – including the release levers for the 959 – already produced using 3D printing, Porsche is more familiar with technology than most. From now on, the manufacturer goes even further by 3D printing whole pistons for its most powerful 991 generation 911, the GT2 RS.While it doesn’t look like these 3D-printed pistons will end up in many production Porsches anytime soon, they represent little more than a simple engineering flex. There are very real mechanical advantages here. For starters, they weigh 10% less than their forged equivalents and have a built-in and closed cooling duct in the piston crown which apparently cannot be reproduced using traditional manufacturing methods. The reduction in weight and temperature translates into an additional 30 horsepower over the already powerful 700 of the GT2 RS.
