3D Bioprinting in Biomedical Applications

Abstract

Three-dimensional (3D) printing is an accelerating innovation in a variety of areas, which include automobiles, medicine, manufacturing, aerospace, art, education, marine, robotics, and so on. Recent technology advancements have enabled 3D printing of biocompatible components, cells, and their accompanying materials into sophisticated 3D functioning living tissues as well as other structures. It is employed in the biomedical field for the treatment and rehabilitation, restructuring, and repair of a variety of cell types, organs, tissues, and other structures by revealing previously unattainable freedom layers, such as increased design complexity. In the medical industry, 3D bioprinting has emerged as a disruptive technology in satisfying worldwide demands for organ replacement or tissue regeneration. The bioink used in bioprinting is the most critical component in the fabrication of functional organs or tissue frameworks. Bioinks used in bioprinting are regarded to be necessary because they help cells grow into a particular organ or tissue. Thus, selecting bioink characteristics, combining various production procedures, and improving their attributes are crucial for generating more effective bioinks for organ printing. To better understand this emerging problem, this research provides a basic introduction to bioprinting technology as well as future prospects for usage in various applications. Tissues, bones, tracheal splints, heart tissues, and cartilaginous tissues have all been recognized as potential prospects for 3D bioprinting.
