Abstract: The present invention relates to a bio-ink composition for bio-printing comprising a polymer into which methacrylate is introduced, a crosslinking agent having 1-10 acrylate functional groups, and a photoinitiator; a method for preparing same; and a printing biological structure for controlling physical properties using same. The bio-ink composition for bio-printing prepared according to the present invention can be implanted in vivo and has a very high degree of biocompatibility or cell viability. In addition, the bio-ink composition of the present invention can be effectively utilized for bio-printing because a biological structure can be produced that is capable of controlling physical properties or in vivo application even when irradiated with light for a short period of time.
