Abstract Scope |
A key advantage of additive manufacturing (AM) is that it allows the production of parts with complicated geometries, but co-design of the parts and the processing is essential. For example, the fabrication of heat exchangers requires the use of complex thin-wall structures to improve heat exchange efficiency. Although AM allows such complicated shapes to be built, oftentimes the processing parameters must be adjusted based on the geometry because geometry has a large impact on thermal gradients during the building process. In this work, the processing parameters for the laser powder bed fusion (LPBF) process were varied to determine the optimal parameters for producing thin-walled parts that could be used in a heat exchanger. The novel superalloy MHA3300 was used for this study because its printability and excellent creep properties at high temperatures make it attractive for this application. |
