This research evaluated the effects of LSP on a Ti-6Al-4V alloy, an \u03b1 + \u03b2 titanium alloy manufactured by wrought and additive manufacturing used in biomedical and aerospace applications. Samples manufactured by conventional processes and additive manufacturing were treated under the following conditions: Pulse width of 6 ns, wavelength of 1064 nm, scan density of 2500 pulses\/cm2, pulse energy of 0.750 J, and repetition frequency of 10 Hz. The mechanical response was evaluated in terms of residual stress, microhardness, and microstructure before and after treatment. The results showed significant improvements, reaching compressive residual stress fields of up to \u2212800 MPa and a 22% increase in microhardness, and grain refinement from 18.16 \u03bcm to 5.54 \u03bcm. These results confirm the effectiveness of LSP in improving the surface integrity and mechanical behavior of Ti64 components, regardless of their manufacturing method.<\/jats:p>","DOI":"10.3390\/ma19081582","type":"journal-article","created":{"date-parts":[[2026,4,15]],"date-time":"2026-04-15T10:30:23Z","timestamp":1776249023000},"page":"1582","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Comparison of the Effects of LSP Treatment on Wrought and Additive Manufactured Ti-6Al-4V Samples"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-8330-234X","authenticated-orcid":false,"given":"Irvin Alejandro","family":"Guillen-Virgen","sequence":"first","affiliation":[{"name":"University Centre for Exact Sciences and Engineering (CUCEI), University of Guadalajara, Blvd. Marcelino Garc\u00eda Barragan #1421, Guadalajara 44430, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gilberto","family":"Gomez-Rosas","sequence":"additional","affiliation":[{"name":"Department of Physics, University Centre for Exact Sciences and Engineering (CUCEI), University of Guadalajara, Blvd. Marcelino Garc\u00eda Barragan #1421, Guadalajara 44430, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eduardo","family":"Casta\u00f1eda-Paredes","sequence":"additional","affiliation":[{"name":"Department of Electrical Mechanical Engineering, University Centre for Exact Sciences and Engineering (CUCEI), University of Guadalajara, Blvd. Marcelino Garc\u00eda Barrag\u00e1n #1421, Guadalajara 44430, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-6993-0171","authenticated-orcid":false,"given":"Martha Guadalupe Arredondo","family":"Bravo","sequence":"additional","affiliation":[{"name":"Department of Physics, University Centre for Exact Sciences and Engineering (CUCEI), University of Guadalajara, Blvd. Marcelino Garc\u00eda Barragan #1421, Guadalajara 44430, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2619-8874","authenticated-orcid":false,"given":"Olga","family":"Klimova-Korsmik","sequence":"additional","affiliation":[{"name":"Institute of Laser and Welding Technologies, Saint-Petersburg State Marine Technical University, Saint-Petersburg 190121, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marina","family":"Gushchina","sequence":"additional","affiliation":[{"name":"Institute of Laser and Welding Technologies, Saint-Petersburg State Marine Technical University, Saint-Petersburg 190121, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3893","DOI":"10.1063\/1.1661837","article-title":"Laser shock-induced microstructural and mechanical property changes in 7075 aluminums","volume":"43","author":"Fairand","year":"1972","journal-title":"J.
