Delphi is printing parts out of a liquid polymer bath, using a process created by Carbon, a Redwood, Calif. company. This new 3D printing process makes complex shapes that can’t be made by mold injection and the parts are stronger, yet lighter. A special window allows light and oxygen to pass through. The light turns liquid plastic into a solid. The oxygen inhibits resin from solidifying and sticking to the window. Delphi is installing a number of parts made from this unique 3D printing process, including this connector, into a fleet of 25 cars in Warren, Ohio for durability testing. Delphi is seriously looking at mass producing parts from this unique 3D process.
