This paper presents a multi-jet polishing (MJP) method for post-processing additively manufactured (AMed) surfaces, particularly those with complex surface geometries. Through systematic polishing tests on 316L stainless steel (SS) prepared by powder bed fusion, the polishing performance and the effect of key parameters are evaluated. The results demonstrate the effectiveness of MJP in obtaining nanometric surface roughness on AMed 316L SS, indicating the potential wide application of MJP for post-processing complex AMed surfaces.
Post-process finishing of the additively manufactured (AMed) surfaces is still a critical issue, especially for the AMed surfaces with complex surface geometry, which largely limits the application of additive manufacturing. Hence, this paper presents a multi-jet polishing (MJP) method for post processing of AMed surfaces, utilizing a number of pres-surized micro/nanometer abrasive water jets. A group of systematic polishing tests are conducted on 316L stainless steel (SS) prepared by powder bed fusion, to test the polishing performance, as well as the effect of key parameters. Moreover, surface integrity charac-terization and analysis are also carried out to make full evaluation of the MJP process on AMed 316L SS. The results indicate that MJP is effective for the post processing of AMed 316L SS, to obtain nanometric surface roughness on AMed surfaces, shedding the light on wide application of MJP for AMed complex surfaces.(c) 2023 The Author(s).
