Bio printing is a form of Addictive manufacturing that uses cells and biometricals instead of traditional metals and plastic to use 3D constructions these biometerials are called bio ink .The ability to print various biological materials and cells along with various tissue sack folders materials 

The produce functional cells, tissue and organ to repair Replies or enhance biological functions that has been lost decisive or injuries. It is also most promising approaches to solving the problems of shortage of suitable organs for transplantation

One of its goal is artificial organs there are some different types printing techniques . Inkajat extractions lesser assistant. These are the some techniques using to printing. Here using bio ink for printing  Bio ink and hydrogen are the materials to bioping.

Organ printer is incorporated with two technology . And they are tissue engineering and bio printing bio printing also known as 3D printing why because bioping is an dimension of 3 sides of an organ or anythings. That's why bio printing is also known as 3D printing. Instead of paper Petri dishes are used instead of ink and paper and some chemicals is called closer linker. Closer linker are used  first step is make cells this cells completely for the patients. individual patients 

What is Bio ink

• A small body biopsy is taken from the patient 
• The fibroblast from the skin or isolated and cultivated into vitro 
• Does fibroblast are reprogrammed in to the organ cells in need it 
• Here does reprogramid cells are using as the  ink for bio printer 
• Printers more back and forth dropping out one bioink particle at a time to form 1 layer
• Printer prints out one layer Cells at a time on a Bio paper which is made up of collagen water and hydrogen 
• Layers are printed on the top of each others
• After cells fuse then the bio paper is removed.

Benefits

Most organs can be made with this technology for using in human body. as long as the fibroblastic can be reprogrammed to be the organ cells

No organ rejections will occur because it will be the patients on DNA a drugs needed for the regular organ replacement

Can bypass the organ donor list

Can be used to treat anyone since the organ is made for the individual 

Bio printing is and good for our current few current and future but also there are some challenges its facing. Let's talk about the challenges of bio printing in tissue engineering 

1. Is technology is still very expensive 
2. Organ that is being made  can die if blood vessels are created into the organ 
3. Using steam cells is still control version 

Still this will take lot of time to actual Maken organ 

Bio printing is an very very useful techniques for our present then there is lot of challenges facing that that why it's coming delay maybe in the future it will come and its will come common in our present or future life

When it's come to develop and its come to make an organ technique then this is an very useful techniques for each and every humans and it will help to save a lot of lives
