Abstract
A three-dimensional cell culture scaffold and preparation method thereof. The preparation method comprises the following steps: designing, according to a shape of a cell culture device, a shape of the three-dimensional cell culture scaffold; printing once by a 3D printer to form the three-dimensional cell culture scaffold; performing a surface treatment, by a surface treating agent, on the three-dimensional cell culture scaffold manufactured by 3D printing to obtain a resultant three-dimensional cell culture scaffold. By adopting a three-dimensional printing technology to manufacture a three-dimensional fibrous cell culture scaffold having a three-dimensional fibrous network structure, raw materials and a manufacturing time can be saved, reducing production costs, increasing production efficiency, decreasing power consumption, preventing a flaw in the conventional manufacturing technique, and facilitating large-scale intelligent manufacturing.
