| Abstract Scope |
Additive manufacturing allows for thinner and more complex design features than what traditional manufacturing methods can offer. Inconel 718 is a suitable material for thin feature applications at high temperatures due to its age hardenability, which allows for retention of desirable tensile properties at elevated operating temperatures. Thin wall parameters were developed for Inconel 718 printed on a Laser Powder Bed Fusion (LPBF) printer using fine powder and a roller recoater. Walls with a thickness of 200 µm and single pass walls were achieved by optimizing primary processing parameters like laser power, scan speed, and contour order. The resulting parameter set created stable 200 µm thin walls with as-printed roughness (Ra) values around 4 µm. Stable and fully continuous single pass thin walls were also created at thickness of 75 and 100 µm. Additionally, etched sample micrographs were taken to evaluate the microstructures. |
