However, traditional solid titanium implants exhibit an elastic modulus (90\u2013115 GPa) significantly higher than that of human bone (10\u201330 GPa), leading to stress shielding and implant loosening. To address this, porous titanium alloys have been developed to better match bone elasticity. Additive manufacturing, particularly selective laser melting (SLM), enables precise control over pore size and porosity, thereby tuning mechanical properties. Nevertheless, SLM-produced porous structures often suffer from powder adhesion, which compromises bone integration and patient safety. In this study, bulk Ti6Al4V samples were fabricated via SLM with a fixed laser power of 200 W and varying scanning speeds (800\u20131400 mm\/s). Density measurements and surface defect analysis identified 1200 mm\/s as the optimal scanning speed. Cubic unit cell scaffolds with different pore diameters (400, 600, 800 \u03bcm) and porosities (60%, 80%) were subsequently designed. Compression tests revealed that scaffolds with a 400 \u03bcm pore diameter and 60% porosity exhibited the highest compressive strength (794 MPa) and fracture strain (41.35%). Chemical polishing using a diluted HF-HNO3 solution (1:2:97) effectively removed adhered powder without significant structural degradation, with 40 min identified as the optimal polishing duration.<\/jats:p>","DOI":"10.3390\/ma18081864","type":"journal-article","created":{"date-parts":[[2025,4,18]],"date-time":"2025-04-18T08:24:07Z","timestamp":1744964647000},"page":"1864","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Preparation and Post-Processing of Three-Dimensional Printed Porous Titanium Alloys"],"prefix":"10.3390","volume":"18","author":[{"given":"Tairong","family":"Li","sequence":"first","affiliation":[{"name":"College of Materials Science and Engineering, Fuzhou University, Fuzhou 350108, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengyu","family":"Xu","sequence":"additional","affiliation":[{"name":"College of Materials Science and Engineering, Fuzhou University, Fuzhou 350108, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinzhi","family":"Yao","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, The Second Affiliated Hospital of Fujian Medical University, Quanzhou 362000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liping","family":"Deng","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering and Automation, Fuzhou University, Fuzhou 350108, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0445-9532","authenticated-orcid":false,"given":"Bingshu","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Materials Science and Engineering, Fuzhou University, Fuzhou 350108, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3441","DOI":"10.1016\/j.jma.2024.10.001","article-title":"Research advances of magnesium and magnesium alloys globally in 2023","volume":"12","author":"She","year":"2024","journal-title":"J.
