3D printing is the process of creating three- dimensional structure of biomaterials by means of computer control. With respect to the nano-scale dimensions the biomaterials are classified into three types as- Nano-particle (3D), Nano-fiber(2D) and Nano-sheet (1D). 3D bioprinting is the formation of numerous cell patterns by using printing techniques along with the layer-by-layer method to produce tissue mimetic structures without any harm in cell function that can be further used in tissue engineering. Electrospinning technology means deposition of polymer nanofibers on an object by using high voltage to a liquid polymer solution. Bioprinting helps in the research of drugs and pills by printing tissues and organs. It is also used for micro devices and microarrays. The 3D printing materials market is expected to reach USD 1,809.5 Million by 2021 from USD 530.1 Million in 2018, at a CAGR of 23.40%.
