These techniques include conventional extrusion at 350 \u00b0C (CE-350) and KOBO extrusion at both room temperature (KOBO-RT) and 350 \u00b0C (KOBO-350). The extrusion processes, regardless of the method used, effectively densified the alloy, fragmented the primary silicon network, and refined the grain structure. Notably, a microstructure analysis indicated that the CE-350 method produced the finest grains, whereas the KOBO-350 method resulted in the largest grains. From a mechanical perspective, extrusion significantly increased ductility\u2014rising from 2.4% to more than 14% elongation\u2014while decreasing strength compared to the as-built state. Among the extruded samples, CE-350 provided the best balance of strength and ductility, exhibiting a yield strength of 186 MPa and a ductility of 18.1% elongation. Overall, the results demonstrate that while extrusion enhances ductility, it does so at the expense of strength, with conventional extrusion yielding a more favorable property balance for this alloy under the tested conditions.<\/jats:p>","DOI":"10.3390\/sym17050709","type":"journal-article","created":{"date-parts":[[2025,5,6]],"date-time":"2025-05-06T05:54:43Z","timestamp":1746510883000},"page":"709","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["The Influence of Grain Structure on Mechanical Properties of LPBF AlSi10Mg Alloy Obtained via Conventional and KOBO Extrusion Process"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4108-0903","authenticated-orcid":false,"given":"Przemys\u0142aw","family":"Snopi\u0144ski","sequence":"first","affiliation":[{"name":"Department of Engineering Materials and Biomaterials, Silesian University of Technology, Konarskiego Street 18A, 44-100 Gliwice, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6484-200X","authenticated-orcid":false,"given":"Pawe\u0142","family":"Ostachowski","sequence":"additional","affiliation":[{"name":"Faculty of Non-Ferrous Metals, AGH University of Krakow, A.
