| Abstract Scope |
Plasma Transfer Arc Additive Manufacturing (PTA-AM) is a developing technology in printing additive manufacturing (AM) parts. A popular material used in many industries, 17-4 precipitation hardened (PH) stainless steel, was selected. Torch offset, center gas, powder gas, shield gas, nozzle angle relative to the welding direction, current, powder flow rate and table speed are all parameters that need to be controlled. A Taguchi L’18 DOE was used to build 18 walls to narrow the processing parameters down to the most influential ones, using signal-to-noise ratio analysis on Minitab. Powder flow rate, current, and table speed were used in a second Taguchi L’9 DOE to verify they could produce more complex shapes with acceptable mechanical properties. The best and worst cylinder and square were taken for heat treatment and hardness tests. A new dimensionless number, the heat ratio, is proposed to assess the quality of the part being built. |
