Jay Leno is a visionary. As the owner of a fleet of vintage cars with numerous obsolete parts, he knows firsthand just how difficult it is to maintain such vehicles.
The necessary replacement parts are either impossible to find, expensive to replicate using traditional machining methods, or not quite the right fit. Enter 3D printing to the rescue. Some have uses the NextEngine 3D scanner and Dimension 3D printer to great results.
The scanner can create a highly detailed digital model, while the 3D printer replicated an exact copy in plastic. This is used to create a mold, or in some cases, machinists can use the direct laser sintering method to create a replacement part in cobalt-chrome.
The advantage of this technique is that the result is more precise, and any mistake can be corrected at a negligible cost. Contrast this with the cost of a machinist, who will still be paid, even if there are discrepancies in the output. The result with the 3D printers is more precise, less costly, and less time-consuming.
The scanner and printer are not cheap, but if you have the money to spend, this is a good investment, especially if you are a vintage machine enthusiast.
