Oracle posted an interesting video with designer Aaron Perry explaining that they can use a 3D printer to make parts straight from digital files in their CAD system. They can “print” parts in titanium, aluminum or plastic. The drawings on Aaron’s screen in the video are the AC Class yacht. You can see the joint where the bow section unbolts and the extension or “horn” on the stern for the umpire light stack, the GPS antenna and the agile TV camera. In addition, you can see that the rudder position is very different from the AC45X “sport” boat the team is testing in Bermuda.
