3D Printing’s Expanding Role
22. February 2013
Jesel’s Ray Frattone reflects on the company’s use of 3D printing.
If communication between people was perfect, then Jesel Inc. would rarely need prototyping, says company manufacturing manager Ray Frattone. The company, which makes valvetrain components for racecar engines, bought a Dimension 3D printer from Stratasys to print models of proposed part designs. Sharing these models with customers is a way of asking, in effect, “Is this what you had in mind?”
Being able to provide a solid prototype in this way, which allows the customer to study the part design and test-fit it in assembly, has saved Jesel enough money in avoided rework to pay for the 3D printer several times over.
Meanwhile, having the 3D printer in-house has been liberating. The company continues to find uses for it. After prototyping, another valuable application has involved making holding fixtures for the shop’s laser marking machine. Setup time is now quick on this machine, thanks to fixtures that are tailored to particular parts.
The printer has even played a role in marketing. At a tradeshow important to Jesel (the recent Performance Racing Industry show), parts in Jesel’s booth were mounted for optimum display using custom holding panels that had been created through 3D printing.
