Surface Finish on A356-T6 Cast Parts using Additive Manufactured Sand Molds

Abstract Details

The objective of this research is to determine if surface finish influences the mechanical properties of cast heat treated aluminum (A356-T6). Binder jetting of sand allows for complex molds to be designed and printed to decrease the amount of time, cost and material. This project is separated into three phases. First phase of the project is the development of a benchmark casting and evaluation of surface roughness. In this phase, the surface finish of several angles of print orientation were compared. Certain angles produced a very noticeable stair step feature. Second phase of the project characterizes the static tensile and fatigue properties of A356-T6 cast flat bars from molds of four print orientation angles (0°, 5°, 15°, 30°). Lastly, the third phase of the project is fluid penetrant inspection (FPI) testing. The intent of this phase is to determine if stair step features would affect the outcome of this common nondestructive evaluation process.
