Could 3D printing tech be the next big step in engine development?Technology for 3D printing is advancing at an amazing pace, but one neat thing that may have gone unnoticed at the RAPID + TCT convention showcasing this type of construction is very relevant to our interests. It may not be a shock to some, but visually, these 3D printed pistons are wild.Printed load-bearing parts are still in their infancy, which is likely why we see these two vastly different designs by a company called Oerlikon. One features a mesh type of structure under the pin bore. It’s an interesting concept to see, but we aren’t really sure about the practicality of this design. Oil could load up unevenly, causing all sorts of issues. So on to the next one.The second design looks a little more promising, with “rods” offering support. Oil distribution wouldn’t be caught up in any smaller supports, and this could potentially be strong. That said, a bigger question remains.Is it worth it?Taking out weight from a rotating assembly always has some benefits. Overall, 3D printing would assuredly give one of the lightest method of construction possible, but we do know it hasn’t exactly been proven yet. Cost versus benefit might not come around to the average consumer market for a few years, especially with how well-built pistons are now. We’re not suggesting that pistons don’t need to be re-invented, in fact, we are excited to see the technology develop.In addition to obvious benefits for pistons, 3D printing can effectively eliminate just about any unnecessary weight on other parts of the engine as well. That could be a game changer for both performance engines and also – it must be said – for engines primarily focused on efficiency, too. #gallery-2 { margin: auto; } #gallery-2 .gallery-item { float: left; margin-top: 10px; text-align: center; width: 25%; } #gallery-2 img { border: 2px solid #cfcfcf; } #gallery-2 .gallery-caption { margin-left: 0; } /* see gallery_shortcode() in wp-includes/media.php */ <br style="clear: both" />
