Multiscale characterization confirms a rhombic mesh macrostructure with uniform fibers and fusion-enhanced nodal junctions, demonstrating synergistic control of electrohydrodynamic forces and surface tension over microfiber deposition. Mechanical testing reveals triphasic tensile behavior (elastic-plastic-fracture), where 5 mm scaffolds exhibit 38% enhanced peak load due to superior interfacial bonding and densified geometry, while 8 mm counterparts suffer premature failure from structural weakening. Fractography identifies brittle fracture initiation at stress-concentrated nodes versus ductile dominance in straight segments, confirming co-regulation by intrinsic material properties and architecture. Compression tests demonstrate characteristic load-holding-recovery behavior, with 20% increased load-bearing capacity and enhanced elastic recovery in larger scaffolds. This work establishes a structure\u2013property correlation framework for optimizing degradable vascular implants, providing novel methodologies and theoretical foundations for clinical compatibility.<\/jats:p>","DOI":"10.3390\/polym18010074","type":"journal-article","created":{"date-parts":[[2025,12,29]],"date-time":"2025-12-29T07:52:59Z","timestamp":1766994779000},"page":"74","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Electric Field-Driven Melt Jetting Polycaprolactone Rotational Printing of Fully Degradable Vascular Stents and Mechanical Characterization"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8824-6707","authenticated-orcid":false,"given":"Yanpu","family":"Chao","sequence":"first","affiliation":[{"name":"School of Mechatronics Engineering, Xuchang University, Xuchang 461000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fulai","family":"Cao","sequence":"additional","affiliation":[{"name":"School of Mechatronics Engineering, Xuchang University, Xuchang 461000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2201-7482","authenticated-orcid":false,"given":"Hao","family":"Yi","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Mechanical Transmission, Chongqing University, Chongqing 400044, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuai","family":"Lu","sequence":"additional","affiliation":[{"name":"School of Mechatronics Engineering, Xuchang University, Xuchang 461000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chengyan","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Mechatronics Engineering, Xuchang University, Xuchang 461000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui","family":"Cen","sequence":"additional","affiliation":[{"name":"School of Mechatronics Engineering, Xuchang University, Xuchang 461000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhongfu","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Mechatronics Engineering, Xuchang University, Xuchang 461000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yihang","family":"Yao","sequence":"additional","affiliation":[{"name":"School of Mechatronics Engineering, Xuchang University, Xuchang 461000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaobo","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Mechatronics Engineering, Xuchang University, Xuchang 461000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"476","DOI":"10.1161\/CIRCINTERVENTIONS.112.970954","article-title":"Percutaneous coronary intervention versus optimal medical therapy in stable coronary artery disease: A systematic review and meta-analysis of randomized clinical trials","volume":"5","author":"Pursnani","year":"2012","journal-title":"CIRC Cardiovasc.
