Despite its strength, it is limited by a small number of processable polymers. Therefore, to broaden the library of materials for MEW, we investigated the printability of poly(ethylene oxide terephthalate)\u2010poly(butylene terephthalate) (PEOT\u2010PBT), a thermoplastic elastomer. The effect of different printing parameters and material thermal degradation are studied. It is observed that the material is stable for &gt;60 min at a printing temperature of 195\u00a0\u00b0C in a nitrogen environment. Next, two types of designs are printed and characterized: mesh\u2010like and semi\u2010random scaffolds. For both types of designs, PEOT\u2010PBT scaffolds reveal a higher yield strain, and lower Young's modulus as compared to control polycaprolactone scaffolds. Biological studies performed using mouse embryonic fibroblasts (NIH\u20103T3) show good cell viability and metabolic activity on all print scaffolds. SEM imaging reveals actively migrating cells on PEOT\u2010PBT mesh scaffolds after 24 h of culture and 98.87% of pore bridging by cells after 28 days of culture. Immunofluorescence staining shows decreased expression of alpha\u2010smooth muscle actin from day 14 to day 28 in PEOT\u2010PBT mesh scaffolds. Overall, it is shown that melt electrowritten PEOT\u2010PBT scaffolds have great potential for soft tissue regeneration.<\/jats:p>","DOI":"10.1002\/adhm.202402914","type":"journal-article","created":{"date-parts":[[2024,12,11]],"date-time":"2024-12-11T04:33:19Z","timestamp":1733891599000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Melt Electrowriting of Elastic Scaffolds Using PEOT\u2010PBT Multi\u2010block Copolymer"],"prefix":"10.1002","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0799-7870","authenticated-orcid":false,"given":"Armin","family":"Amirsadeghi","sequence":"first","affiliation":[{"name":"Polymer Science Zernike Institute for Advanced Materials University of Groningen  Nijenborgh 3 Groningen 9747 AG The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5579-3613","authenticated-orcid":false,"given":"Pavan Kumar Reddy","family":"Gudeti","sequence":"additional","affiliation":[{"name":"Biotechnology Centre The Silesian University of Technology  B.
