The German parts manufacturer Mahle, industrial machine manufacturer Trumpf, and automaker Porsche have 3D printed pistons for the well-known 911 GT2 RS that are not only stiffer but also lighter. They have also integrated and closed the cooling duct in the piston crown, thus enhancing its power and efficiency. These 3D printed pistons will not be entering production any time soon since the piston crew feature cannot be reproduced via the conventional manufacturing methods. However, it should be noted that they do offer mechanical benefits since they weigh 10% less than the forged ones. These features, including the likes of reduction in weight and temperature, can help generate an extra 30 horsepower apart from the 700 horsepower that GT2 RS is already capable of generating. The 3D printed pistons have been created using the high-purity metal powder and relied on a laser metal fusion process for its creation. This means that it has been created using a laser beam that heats and t...
