Three dimensional (3D) bioprinting is the utilization of 3D printing and 3D printing–like techniques to combine cells, growth factors, and biomaterials to fabricate biomedical parts that maximally imitate natural tissue characteristics. Emerging innovations span from bioprinting of cells or extracellular matrix deposited into a 3D gel layer by layer to produce the desired tissue or organ. Three dimensional (3D) bioprinting utilizes the layer-by-layer method to deposit materials known as bioinks to create tissue-like structures that are later used in medical and tissue engineering fields. Currently bioprinting is used to print tissues and organs to help research drugs and pills. The recent advances in 3D printing are a testament to the promise of this technology and its profound utility in research and regenerative medicine.
