    摘要: Provided in the present application are a three-dimensional forming method and system. The method comprises: step 1, controlling, by means of an acoustic wave, a bio-ink in an acoustic resonant cavity to form a cell cluster pattern M1; step 2, performing controllable photocuring on a pre-curing position of the cell cluster pattern M1, so as to obtain a cured and formed structure; step 3, transferring the cured and formed structure; step 4, controlling, by means of an acoustic wave, the bio-ink in the acoustic resonant cavity to form a cell cluster pattern M2, and adjusting the position, in the bio-ink, of the cured and formed structure of step 3, such that the position is accurately joined with a pre-curing position of the cell cluster pattern M2; step 5, performing controllable photocuring on the pre-curing position of the cell cluster pattern M2, so as to obtain a cured and formed structure; and circularly executing steps 3-5 a preset number of times, so as to obtain a three-dimensional tissue structure. By means of the present application, three-dimensional printing can be realized by means of the coupling of an acoustic wave and photo-curing technology, thereby improving the printing accuracy and efficiency of a three-dimensional heterogeneous tissue structure.
