Description

technical field [0001] The invention relates to the technical fields of 3D printing technology and gel materials, in particular to a 3D printing device based on a shear-thinning gel. Background technique [0002] Gel materials have broad application prospects in the fields of biology, electronics, and sensing because of their good processing and molding, as well as excellent biocompatibility and physical properties. For example, polymer hydrogels can be used in various applications such as soft robotics, biology, and transparent touch panels, and graphene hydrogels can be used in electronics, sensing, and energy storage. However, the applications of these gels are limited by their manufacturing methods, which have traditionally relied on molding and casting. These traditional fabrication methods limit the geometric complexity of gels. 3D printing gel materials can avoid the above limitations, and can quickly and conveniently print devices with large geometric complexity. ...
