over the past decade. By controlling the size, shape, and architecture of the bioprinted
constructs, 3D bioprinting allows for the fabrication of tissue/organ-like constructs with strong
structural–functional similarity with their in vivo counterparts at high fidelity. The bioink, a
blend of biomaterials and living cells possessing both high biocompatibility and printability,
is a critical component of bioprinting. In particular, gelatin methacryloyl (GelMA) has shown …
