| Abstract Scope |
Complex ordered and disordered networks have unique transport and mechanical properties, however their manufacture into metallic test articles can be very challenging due to their unorthodox solid geometries. Powder bed fusion (PBF) additive manufacturing is a promising process for fabricating solid network geometries in 2D and 3D, however it must overcome issues such as fine feature resolution on the same size scale as the powder feedstock and thermal issues due to unsupported overhanging features. This research examines the limits of manufacturing complex disordered geometries by a) developing printable STL file generation techniques from matrices deploying mathematical algorithms, b) systematic evaluation of unsupported sub-millimeter to millimeter size scale features for microstructure integrity and roughness, and c) identifying strategic and very limited overhang supports which are removable within the complex geometry. |
