bioprinting: Presently science has advanced a lot in the medical field. It is now more appropriate to compare a doctor to God. Scientists in this category have won over the technique of making artificial limbs. Now no human will die in the absence of organ donors. Now the artificial form of organs can be made according to the need and it has also been found to be successful in trials so far.
Before knowing the advantages of 3D bioprinting technology, we should know what is 3D bioprinting?

What is 3-D Bio Printing

3D 'bioprinting' is an additive manufacturing process where biometric such as cells and growth factors are combined to form tissue-like structures. Which is an exact copy of natural tissues and also replicates the procedure.

This technique uses a material called Bio Ink to make all these structures layer by layer. This technique is highly suitable in the field of medicine and bioengineering. Currently, human cartilage has been used in production and reconstruction and improvement through this technique. Sterile printing conditions are essential for cell life and a better cell matrix.

Bioprinting is done through 3 processes.

1. Pre-Bio Printing: In this step, a digital model of the organ is to be produced. It uses techniques like CT scan and MRI scan.

2. Bio Printing: This is the actual printing process where bio-ink is added to the cartage and the ink is deposited according to the digital model.

3. Post Bio Printing: In this step mechanical and chemical stimulation of the printed organ is done to make it a stable structure.

How does bioprinting work?

3D imaging: Standard CT scan or MRI scan is used for precise quantification of tissues. It should be so precise that no further changes are needed.

3D modeling: The blueprint is prepared by AutoCAD software [5]. Which is in every detail all the information from layer to layer. At this stage, some improvements can be made to remove any kind of defects.

Bio Ink Preparation: Bio Ink is a combination of living cells and compatible bases such as collagen, gelatin, hyaluronan, silk, alginate or nano-cellulose. Later it is kept in the necessary nutrients so that it can survive. All of this depends on the patient's physical structures.

Printing: These process biofacies layer by layer where the thickness of all layers is 0.5 mm or less.

Solidification: As deposition takes place, the layer begins to freeze in its shape. This process is called cross-linking, which also uses UV light, special chemical or heat.

Advantages of 3D Bio Printing.

Artificial limbs: Due to the lifestyle of today, many cases are seen which sometimes cause liver or kidney or heart failure. In such situations, keeping the patient on a life support system throughout life can prove costly for him. Therefore, due to this technique, anyone can produce and re-install prostheses.

Pharmaceutical Testing: And animals have been used for testing of drugs so far, but now we can produce pharmaceutical tests on them by producing related tissues. Which will easily get information about the side effects of medicines?

Cosmetic Surgery: This technique will be more beneficial especially in plastic surgery and skin grafting.

Bone tissue regeneration: also beneficial in the prosthetic foot or arm and dental application.
