However, the implementation of precise gel printing is a difficult task due to the high requirements for \u201cink\u201d. In this paper, we propose the use of gel-like materials based on sodium alginate as \u201cink\u201d for the implementation of the developed technology of extrusion-based 3D printing. Rheological studies were carried out for the developed alginate ink compositions. The optimal rheological properties are gel-like materials based on 2 wt% sodium alginate and 0.2 wt% calcium chloride. The 3D-printed structures with complex geometry were successfully dried using supercritical drying. The resulting aerogels have a high specific surface area (from 350 to 422 m2\/g) and a high pore volume (from 3 to 3.78 cm3\/g).<\/jats:p>","DOI":"10.3390\/gels7030092","type":"journal-article","created":{"date-parts":[[2021,7,14]],"date-time":"2021-07-14T21:56:51Z","timestamp":1626299811000},"page":"92","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Extrusion-Based 3D Printing for Highly Porous Alginate Materials Production"],"prefix":"10.3390","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7806-1426","authenticated-orcid":false,"given":"Natalia","family":"Menshutina","sequence":"first","affiliation":[{"name":"International Science and Educational Center for Transfer of Pharmaceutical and Biotechnologies, Mendeleev University of Chemical Technology of Russia, Miusskaya pl. 9, 125047 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrey","family":"Abramov","sequence":"additional","affiliation":[{"name":"International Science and Educational Center for Transfer of Pharmaceutical and Biotechnologies, Mendeleev University of Chemical Technology of Russia, Miusskaya pl. 9, 125047 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pavel","family":"Tsygankov","sequence":"additional","affiliation":[{"name":"International Science and Educational Center for Transfer of Pharmaceutical and Biotechnologies, Mendeleev University of Chemical Technology of Russia, Miusskaya pl. 9, 125047 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8709-4139","authenticated-orcid":false,"given":"Daria","family":"Lovskaya","sequence":"additional","affiliation":[{"name":"International Science and Educational Center for Transfer of Pharmaceutical and Biotechnologies, Mendeleev University of Chemical Technology of Russia, Miusskaya pl. 9, 125047 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"100248","DOI":"10.1016\/j.mtchem.2020.100248","article-title":"Fused deposition modeling-based additive manufacturing (3D printing): Techniques for polymer material systems","volume":"16","author":"Daminabo","year":"2020","journal-title":"Mater.
