23 Jul 3D printer and 3D printing method of sodium alginate hydrogel
Abstract
The invention discloses a 3D printer and a 3D printing method of a sodium alginate hydrogel. According to the method, a sol-like sodium alginate taken as a printing raw material is solidified through a calcium ion solution, and the sodium alginate hydrogel in a certain three-dimensional shape is obtained through 3D printing. The sodium alginate hydrogel printed by the method is in a continuous and uniform-thickness line shape and has good strength and toughness; a hydrogel model in a specific 3D shape can be prepared by the layer-upon-layer stacked printing method, the hydrogels with different colors or different functions can be obtained by adding pigments of different colors or materials with different functions. The method is simple to operate, safe and environmentally friendly, and cost is low; the method can be used for printing the sodium alginate hydrogel with a 3D structure on a large scale, and a material basis is provided for research areas such as tissue engineering, simulation robots and biosensors, which involve soft body sensing materials.
