EXTRUSION, INKJET AND LASER ASSISTED BIOPRINTING

Abstract—The applicability of 3D bioprinting has increased its visibility in regenerative medicine and tissue engineering. Inks made from biomaterials and bioinks may now be printed more easily thanks to technological advancements that have been made in recent years, which has helped to create structures that closely resemble human anatomy. Cross-linked polymeric materials, including hydrogels, have thus been specifically targeted for the creation of bioinks since they ensure cell growth and adherence. Therefore, this concise study provides a brief history of 3D bioprinting technology and clarifies the primary hydrogels employed in the procedure. Keywords—3D bioprinting; hydrogels; inkjet bioprinting; extrusion bioprinting; laser assisted bioprinting
