Study on the 3D BioPrinting Technology of Hydrogel Tissue Engineering scaffolds

Abstract The precision molding capability of bio-3D printing is the basis for its application in tissue engineering, and SA-Gel two-component hydrogel has been widely used manufacturing engineering scaffolds. extrusionability key point precision. In this paper, starting from concentration, ratio, rheology cross-linking mode hydrogel, research ideas “single factor independent analysis” multi-factor comprehensive are adopted to solve accuracy. Through screening parameters compensation technology, accurate 1D line segment 2D grid structure at 45°C with 2% 8% mass respectively have achieved.
