Types of printing
Simplifying there are two major approaches. In the first, the scaffolding is made and subsequently the BioInk is deposited on them(Biological “ink”) consisting of differentiated cells or stem cells together with numerous other substances. This material mimics the action of extracellular matrix structures that support adhesion, proliferation and differentiation of living cells. All in a sterile environment to avoid contamination phenomena. In the case of the use of stem cells, the complex problem arises of the growth factors to be associated with BioInk which can induce unwanted cell differentiations or behaviors. Among the numerous technologies used in this sector, nanomaterials should be emphasized. In the second, more complex approach, both the scaffold and the BioInk are printed at the same time. All this is theoretically similar to the technique of commonly used multi-head InkJet printers ceramics printing singapore.
Companies and entities active in the sector
There are numerous companies active in the explosive sector of 3DBioprinting, doing a quick search on the web you will come across for example some whose main objective is to develop liver tissue in vivo .for the treatment of a number of liver diseases for which there are currently no effective alternatives to organ transplantation. The ultimate stated goal is to be able to postpone or reduce the need for transplantation. You will also find the commercialization of liver and kidney cells obtained with 3DBioprinting to be used in biomedical and pharmacological research. In Japan there is a company that uses an innovative approach to 3DBioprinting: their technology does not use ‘scaffolding’ on which to use the BioInk but rather generates tissues and organs by fusing the cells together. Recently they have bioprinted human liver tissue that has maintained metabolic capacities functional to drug testing over time.
