Three dimensional (3D) bio-printing is the utilization of 3D printing–like techniques to combine cells, growth factors, and bio-materials to fabricate biomedical parts that maximally imitate natural tissue characteristics. Generally, 3D bioprinting utilizes the layer-by-layer method to deposit materials known as bio-inks. These bio-inks create tissue-like structures that are useful for medical and tissue engineering fields. Bio-printing covers a broad range of bio-materials. Currently, bio-printing is also helpful for 3D bioprinting of tissues and organs to help research drugs and pills.
Bio-printing generally follows three steps, pre-bioprinting, bio-printing, and post-bio-printing. Watch the video to know more –

One of the first steps is to obtain a biopsy of the organ. In the second step, the liquid mixture of cells, matrix, and nutrients known as bio-inks are placed in a printer cartridge and deposited using the patients’ medical scans. When a bio-printed pre-tissue is transferred to an incubator, this cell-based pre-tissue matures into a tissue. The post-bio-printing process is necessary to create a stable structure from the biological material. If we do not welly maintain this process, the mechanical integrity and function of the 3D printed object is at risk. 3D Bioprinting is a developing field and the doctors and scientists are working on this to find solutions to some of the problems and drawbacks the 3-D Bioprinting is having for generating organ tissues.
