Abstract
Abstract Three‐dimensional (3D) bioprinting is a promising method for the fabrication of tissue engineering constructs. The bioprintable materials with cells or other biological parts, which are called bioinks, are arranged layer by layer and make multicellular structures. Not all materials can be printed, and a set of requirements should be met to formulate the appropriate bioink. Poly (ethylene glycol) (PEGDA), as a synthetic polymer, is a promising choice for regenerative medicine applications due to its biocompatibility, ease of crosslinking, and adjustability of its mechanical and chemical properties depending on the application. This review aims to guide and familiarize the reader with the PEGDA‐based bioink as a raw material of the 3D‐bioprinting method, its properties, and applications in soft and hard tissue engineering.
