Bio ink
  Bio ink is an ink that can be used in 3D printers. It is an ink that produces tissues or organs and processes them to remove cells".

Produce background

  Bio ink is ink that can be used in 3D printers. In the past, 3D printers used "biological ink", which used collagen as raw material to produce hydrogels, and had great obstacles in the printing of complex tissues. The research result is that the tissue or organ is treated to remove the cells and produce into "biological ink"".

Technical principle

  Biological ink, in which the mesenchymal stem cells are injected into the tissue that needs to be regenerated, and the artificial tissues that are very similar to the actual organs and tissues are produced by the 3D printer. Compared with the previous "biological ink", the tissue has a greater advantage in cell differentiation

Research and development progress

  In November 2012, researchers from Australia released a new bio ink, a step closer to scientists' dream of printing human tissue from an inkjet printer.
  Scientists have been trying to upgrade the home office equipment such as printers, but they can't find the perfect ink". This process requires a specific medium to ensure cell survival: not only does it provide energy for cells during printing, it also ensures cell survival, and does not block the printer during printing.
  Basically, the medium can be used to print cells at the time of printing so that they can be positioned accurately on paper, and when ink is distributed on paper, it can be broken down into liquid.
  The focus of the study is primarily on the eventual production of specific tissues that can be printed on an inkjet printer layer by layer, such as live band aid. But this cutting-edge technology still makes people feel skeptical, because the liver is composed of a large number of spheres, the kidney is a group of renal pyramid, to copy out of this natural compact structure using a home office equipment is almost impossible. That structure needs to be built layer by layer using the 3D printer. For the time being, skin and other flat tissues are most likely to be printed using inkjet printers.
