It is of great importance to understand the relationship between the surface features and electrochemical properties of manufactured parts. This work studied the influence of surface orientation on the corrosion resistance of 316L stainless-steel (SS) components manufactured with SLM. The corrosion resistance of the samples was measured using linear polarization resistance (LPR) and electromechanical noise (EN) techniques under three different environments, H2O, 3.5 wt.% NaCl, and 20% H2SO4, analyzing the horizontal (XY) and vertical (XZ) planes. The microstructure and morphology of the samples were obtained by optical (OM) and scanning electron microscopy (SEM). The obtained microstructure showed the grains growing up from the fusion line to the melt pool center and, via SEM-EDS, the presence of irregular and spherical pores was observed. The highest corrosion rate was identified in the H2SO4 solution in the XZ plane with 2.4 \u00d7 10\u22122 mm\/year and the XY plane with 1.31 \u00d7 10\u22123 mm\/year. The EN technique along with the skewness factor were used to determine the type of corrosion that the material developed. Localized corrosion was observed in the NaCl electrolyte, for the XY and XZ planes (\u22121.65 and \u22120.012 skewness factors, respectively), attacking mainly the subgrains of the microstructure and, in some cases, the pores, caused by Cl ions. H2O and H2SO4 solutions presented a uniform corrosion mechanism for the two observed orientations. The morphology identified by SEM was correlated with the results obtained from the electrochemical techniques.<\/jats:p>","DOI":"10.3390\/ma14164509","type":"journal-article","created":{"date-parts":[[2021,8,11]],"date-time":"2021-08-11T08:35:52Z","timestamp":1628670952000},"page":"4509","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Corrosion Resistance Measurement of 316L Stainless Steel Manufactured by Selective Laser Melting"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9083-2262","authenticated-orcid":false,"given":"Rigoberto","family":"Guzm\u00e1n-Nogales","sequence":"first","affiliation":[{"name":"Centro de Innovaci\u00f3n e Investigaci\u00f3n en Ingenier\u00eda Aeron\u00e1utica, Facultad de Ingenier\u00eda Mec\u00e1nica y El\u00e9ctrica, Universidad Aut\u00f3noma de Nuevo Le\u00f3n, San Nicol\u00e1s de los Garza 66455, NL, Mexico"},{"name":"Laboratorio Nacional de Manufactura Aditiva y Digital, Apodaca 66629, NL, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francisco","family":"Estupi\u00f1\u00e1n-L\u00f3pez","sequence":"additional","affiliation":[{"name":"Centro de Innovaci\u00f3n e Investigaci\u00f3n en Ingenier\u00eda Aeron\u00e1utica, Facultad de Ingenier\u00eda Mec\u00e1nica y El\u00e9ctrica, Universidad Aut\u00f3noma de Nuevo Le\u00f3n, San Nicol\u00e1s de los Garza 66455, NL, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9072-3090","authenticated-orcid":false,"given":"Citlalli","family":"Gaona-Tiburcio","sequence":"additional","affiliation":[{"name":"Centro de Innovaci\u00f3n e Investigaci\u00f3n en Ingenier\u00eda Aeron\u00e1utica, Facultad de Ingenier\u00eda Mec\u00e1nica y El\u00e9ctrica, Universidad Aut\u00f3noma de Nuevo Le\u00f3n, San Nicol\u00e1s de los Garza 66455, NL, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8040-917X","authenticated-orcid":false,"given":"Omar E.","family":"Lopez-Botello","sequence":"additional","affiliation":[{"name":"Laboratorio Nacional de Manufactura Aditiva y Digital, Apodaca 66629, NL, Mexico"},{"name":"Tecnologico de Monterrey, Escuela de Ingenieria y Ciencias, Monterrey 64700, NL, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan G.","family":"Ram\u00edrez-Rodr\u00edguez","sequence":"additional","affiliation":[{"name":"Centro de Innovaci\u00f3n e Investigaci\u00f3n en Ingenier\u00eda Aeron\u00e1utica, Facultad de Ingenier\u00eda Mec\u00e1nica y El\u00e9ctrica, Universidad Aut\u00f3noma de Nuevo Le\u00f3n, San Nicol\u00e1s de los Garza 66455, NL, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9491-0069","authenticated-orcid":false,"given":"Patricia C.","family":"Zambrano-Robledo","sequence":"additional","affiliation":[{"name":"Centro de Innovaci\u00f3n e Investigaci\u00f3n en Ingenier\u00eda Aeron\u00e1utica, Facultad de Ingenier\u00eda Mec\u00e1nica y El\u00e9ctrica, Universidad Aut\u00f3noma de Nuevo Le\u00f3n, San Nicol\u00e1s de los Garza 66455, NL, Mexico"},{"name":"Laboratorio Nacional de Manufactura Aditiva y Digital, Apodaca 66629, NL, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"305","DOI":"10.1016\/j.matdes.2016.12.095","article-title":"Laser diode area melting for high speed additive manufacturing of metallic components","volume":"117","author":"Arredondo","year":"2017","journal-title":"Mater.
