Abstract Scope |
Over the past decade, additive manufacturing has emerged as a competitive alternative to traditional fabrication; however, the as-printed surface roughness greatly degrades surface sensitive properties requiring a post-processing step before integration for the intended use. A crucial question then becomes, which post-processing technique is appropriate for the part in question? Herein, results from mechanical and chemical techniques will be shared and the differences highlighted. Media blasting was investigated on AM parts with high aspect ratio geometries; variations in surface feature removal were interrogated with different types of media. Conversely, the brightening, smoothing, and deburring of metallic AM parts was chemically investigated through electropolishing. Environmentally friendly baths were targeted for traditional wet electropolishing work in constant and pulsed potential regimes and the results will be compared to commercially available dry electropolishing systems.
