Cummins has sold its first metal part printed on one of its own 3D printers, moving the company a significant step closer to the exciting potential of additive manufacturing.
The part was a low-volume bracket for a customer in Cummins’ New and ReCon Parts division and did not have a current supplier. The company is focusing first on printing low-volume parts as it studies how best to use 3D technology in higher volume manufacturing.
“With this technology you can really unshackle the designer to do things you just can’t do using traditional forms of manufacturing,” said Brett Boas, Director-Advanced Manufacturing at the Cummins Technical Center in Columbus, Indiana (U.S.).

Parts can be made lighter, stronger and more effective using metal 3D printing compared to parts created using more traditional methods that employ molds, molten metal and equipment to precisely cut and shape the part.
3D printing creates three-dimensional objects one ultra-thin layer at a time. If the part doesn’t come out quite right, the designer can simply change the computer design file and print it again; a much faster process than using traditional manufacturing techniques to build a test part.
