MARCH 2018 Additive Manufacturing FEATURE / Metal Additive Manufacturing 26 By Stephanie Hendrixson When Michael Rappach first began working for NextStep Arthropedix, a medical implant company owned by Randy Theken, he was faced with a difficult task: finding a contract manufacturer that could produce the hip and knee products designed by Theken's in-house engineering team. The catch? These medical devices, made from titanium with a trabecular surface structure to mimic cancellous bone, were intended to be manufactured additively. It turned out to be a tall order to find an outside contract manufacturer that could serve as an end-to-end supplier, with the understanding and equipment for metal additive manufacturing as well as the capability to meet stringent requirements for final machining. This dilemma ultimately resulted in the creation of Slice Mfg. Studios, part of the Theken organization that serves as a End-to-End Medical AM Slice Mfg. Studios aims to control and perfect the additive manufacturing of medical devices, from raw material all the way through shipping. Slice Mfg. Studios, part of Theken Companies, was created when its sister medical device design companies couldn't find a suitable manufacturer. Today, Slice aims to control as much of the additive manufacturing process as is possible in the making of medical devices such as these acetabular hip cups.
