3 D printing technology and experimental study of chitosan gel using atomized solidification liquid-assisted extrusion molding
Abstract
\nPurpose\nThis paper aims to propose a suitable atomizing solidification chitosan (CS) gel liquid extrusion molding technology for the three dimensional (3D) printing method, and experiments verify the feasibility of this method.\n\n\nDesign/methodology/approach\nThis paper mainly uses experimental means, combined with theoretical research. The preparation method, solidification forming method and 3D printing method of CS gel solution were studied. The CS gel printing mechanism and printing error sources are analyzed on the basis of the CS gel ink printing results, printing performance with different ratios of components by constructing a gel print prototype, experiments evaluating the CS gel printing technology and the effects of the process parameters on the scaffold formation.\n\n\nFindings\nCS printing ink was prepared; the optimal formula was found; the 3\u2009D printing experiment of CS was completed; the optimal printing parameters were obtained; and the reliability of the forming prototype, printing ink and gel printing process was verified, which allowed for the possibility to apply the 3\u2009D printing technology to the manufacturing of a CS gel structure.\n\n\nOriginality/value\nThis study can provide theoretical and technical support for the potential application of CS 3\u2009D printed gels in tissue engineering.\n
