The viscosity of melts of the composites based on R-BAPB, thermal, mechanical characteristics of the obtained composite samples, their internal structure, and biocompatibility were studied. Simultaneously with FFF printing, samples were obtained by injection molding. The optimal concentrations of carbon fillers in polyimide R-BAPB for their further use in FFF printing were determined. The effect of the incorporation of carbon fillers on the porosity of the printed samples was investigated. It was shown that the incorporation of carbon nanofibers reduces the porosity of the printed samples, which leads to an increase in deformation at break. Modification of polyimide with discrete carbon fibers increases the strength and Young\u2019s modulus sufficiently but decreases the deformation at break. The cytotoxicity analysis showed that the obtained composite materials are bioinert.<\/jats:p>","DOI":"10.3390\/polym14183803","type":"journal-article","created":{"date-parts":[[2022,9,13]],"date-time":"2022-09-13T04:05:41Z","timestamp":1663041941000},"page":"3803","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Development and Processing of New Composite Materials Based on High-Performance Semicrystalline Polyimide for Fused Filament Fabrication (FFF) and Their Biocompatibility"],"prefix":"10.3390","volume":"14","author":[{"given":"Igor","family":"Polyakov","sequence":"first","affiliation":[{"name":"Institute of Biomedical Systems and Biotechnology, Peter the Great St. Petersburg Polytechnic University, Polytechnicheskaya St. 29, St. Petersburg 195251, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0210-7456","authenticated-orcid":false,"given":"Gleb","family":"Vaganov","sequence":"additional","affiliation":[{"name":"Institute of Macromolecular Compounds of Russian Academy of Sciences, V.O., Bol\u2019shoy Pr. 31, St. Petersburg 199004, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4285-7734","authenticated-orcid":false,"given":"Andrey","family":"Didenko","sequence":"additional","affiliation":[{"name":"Institute of Macromolecular Compounds of Russian Academy of Sciences, V.O., Bol\u2019shoy Pr. 31, St. Petersburg 199004, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4823-0695","authenticated-orcid":false,"given":"Elena","family":"Ivan\u2019kova","sequence":"additional","affiliation":[{"name":"Institute of Macromolecular Compounds of Russian Academy of Sciences, V.O., Bol\u2019shoy Pr. 31, St. Petersburg 199004, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elena","family":"Popova","sequence":"additional","affiliation":[{"name":"Institute of Macromolecular Compounds of Russian Academy of Sciences, V.O., Bol\u2019shoy Pr. 31, St. Petersburg 199004, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuliya","family":"Nashchekina","sequence":"additional","affiliation":[{"name":"Institute of Biomedical Systems and Biotechnology, Peter the Great St. Petersburg Polytechnic University, Polytechnicheskaya St. 29, St. Petersburg 195251, Russia"},{"name":"Institute of Cytology, Russian Academy of Sciences, St. Petersburg 194064, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vladimir","family":"Elokhovskiy","sequence":"additional","affiliation":[{"name":"Institute of Macromolecular Compounds of Russian Academy of Sciences, V.O., Bol\u2019shoy Pr. 31, St. Petersburg 199004, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Valentin","family":"Svetlichnyi","sequence":"additional","affiliation":[{"name":"Institute of Macromolecular Compounds of Russian Academy of Sciences, V.O., Bol\u2019shoy Pr. 31, St. Petersburg 199004, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vladimir","family":"Yudin","sequence":"additional","affiliation":[{"name":"Institute of Biomedical Systems and Biotechnology, Peter the Great St. Petersburg Polytechnic University, Polytechnicheskaya St. 29, St. Petersburg 195251, Russia"},{"name":"Institute of Macromolecular Compounds of Russian Academy of Sciences, V.O., Bol\u2019shoy Pr. 31, St. Petersburg 199004, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"799","DOI":"10.1002\/mame.200800121","article-title":"Additive Processing of Polymers","volume":"293","author":"Wendel","year":"2008","journal-title":"Macromol.
