Machining and Directed Energy Deposition (DED) Work Together

Machining is part of metal additive manufacturing, but the 3D printing/machining interconnection is particularly close when the mode of AM is directed energy deposition (DED). This process offers a fast way to obtain a near-net-shape metal part, providing for more economical production of some parts made of challenging metals and other metal parts that are very large — provided machining is available to complete the near-net-shape form. The advance of DED we are seeing will lead to advances in metal AM and machining working together, and Peter Zelinski saw hints of this when he paid a visit to machine tool supplier MC Machinery. Various parts made on the company’s AZ600 DED system illustrate various ways additive and subtractive operations affect one another and interrelate. In the video above, some of the parts I saw and the important points they illustrate. LEARN MORE How DED is advancing and its role is changing: https://www.additivemanufacturing.med...
