Metal additive manufacturing is available in a number of flavors these days, from powder bed electron beam technologies to laser sintering to wire fed directed energy deposition. At the heart of it, the directed energy deposition (DED) additive manufacturing processes, especially those that use a wire feedstock, are very similar to welding. Control of the temperature, linear traverse rate, beam power and wire feed rate are critical parameters essential for a successful print.
But wh…
