Large AM Turbine Blade
A Wisconsin company has produced a stainless steel turbine blade nearly 6 feet long using a continuous 30-hour production run. The structure is 20 inches wide, is hollow inside and has 0.5-mm-wide side walls. It weighs 135 pounds. In addition to the direct-energy deposition (DED) process used here, several other techniques are being used to produce these large-scale AM parts.
