A method for prepring a porous aerogel scaffold includes: adding a photoinitiator and polyethylene glycol diacrylate in a buffer solution, dissolving by heating and evenly mixing, adding Pluronic® F127 (Poloxamer 407) into the mixed solution, and standing at a low temperature to obtain an aerogel scaffold material; printing a hydrogel scaffold by using a 3D printing technology, and performing UV irradiation so that a cross-linking of the hydrogel scaffold is caused to form a three-dimensional scaffold with a stable structure, performing low-temperature soaking to remove Pluronic® F127 (Poloxamer 407), and then freeze drying the three-dimensional scaffold to obtain the porous aerogel scaffold. Wherein, Pluronic® F127 (Poloxamer 407) serves as a sacrificial material which is removed after the 3D printing of the hydrogel scaffold is completed, and then a porous structure can be formed in the scaffold in combination with a freeze drying technology, which facilitates the survival, growth and proliferation of cells during the three-dimensional culture.
