- Аннотация: In recent years, the possibilities of creating biopolymer matrices have expanded considerably due to the use of additive technologies. The problems of existing methods and technologies for obtaining biopolymer matrices based on biopolymer solutions are related to the need to control the kinetics of gel formation during the formation of framework structures in the process of 3D printing. The possibilities of creating hydrogel scaffolds based on thermally reversible hydrogels of agar polysaccharide to be used as universal printing inks in extrusion machines are considered in this article. The conditions for obtaining hydrogels for 3D-printing from agar solutions have been determined. The effect of 4-hydroxy-3-methoxycinnamic acid (ferulic acid, FA) on the structure-forming and thermo-forming process in agar solutions and hydrogels was studied. The materials showed improved physical and mechanical characteristics compared to unmodified samples: an increase in the breaking load by 1.3 times and in relative elongation by 1.64times. The results of the study of the properties of thermally reversible hydrogel agar inks with different contents of crosslinking reagent – FA can be used to create structures of increased strength using 3D-printing technologies.
