Abstract Scope |
Polymer additive manufacturing (AM) has been employed to produce metal parts indirectly via printed tooling (e.g., wax patterns) for investment casting. In investment casting, every feature of the pattern is transferred to the final part, leading to printed patterns having poorer surface finish than traditionally manufactured patterns. Additionally, AM patterns with surface pores can lead to slurry infiltration. Improving the surface finish and sealing the pattern’s surface can significantly improve the surface finish of the final metal part. This study investigates chemically treated printed wax patterns for indirect metal AM via investment casting. In this study, 36 patterns with two different geometries were printed with varying print conditions and surface treated with acetone for different durations. The surface quality of the metal casting was measured using a contact profilometer. These results will help establish a new process chart for surface treatment of increasingly complex AM patterns in indirect metal AM. |
