The new technology allows to print organs in seconds
Source:
On pages of our portal (and our news ) we have about the success in the field of three-dimensional printing of organs. It is believed that in the near future this technology will allow to get rid of donor organs and replaced them with «printed». Only today, with 3D printing of organs there is one significant problem. And it is in most printing technologies. And not so long ago were able to solve a group of scientists from Switzerland.
How to print organs?
In order to understand what is the challenge in organ printing, let's see how this technology works. If you do not go into technical details, for the most part during 3D printing (and no matter what you type — the plastic part or organ), the final form is created by layering material. This allows you to create bodies with complex internal structure. But the main drawback in this case — time. Print one out on unreasonably a lot of time and resources.
However, there is another way — volume the same results for bioprinting, allowing it to form on simultaneously throughout the volume. The method is that the special «mix» out of cells and fixation material alternately from different sides served laser with different penetration capability with a special projector that «shows» only a certain part of the 3D model, which can be seen with «point of view» this projector. In the beam of the projector of the fabric harden. This is so as long as all future authority will not «highlighted».

A Team of scientists from the laboratory of applied photonic devices (Laboratory of Applied Photonics Devices, LAPD) in Switzerland stated that the use of this method allowed them to create the complex shape of the tissue in a biocompatible hydrogel with stem cells. Moreover, these tissues can form organs with a developed circulatory system. But the most amazing is that the printing process takes only a few seconds. Volume printing may allow the creation of new functional bodies
Unlike conventional print — a slow, layer-by-layer process, our technology is much faster and offers more freedom, without compromising the viability of cells, said one of the authors of Damien lottery.
Scientists have successfully (and very quickly) printed tissue heart valves, meniscus, the pulmonary artery and the femur. Moreover, printed tissues and organs can also be used to create interconnected structures like .
This is only the beginning. We believe that our method is relatively easy to start mass production of organs and tissues. Not to mention the fact that you can create «personalized» organs for transplant that will not cause a reaction of the immune response.

Now scientists are focused on masstabling clinical trials and how to declare themselves the authors, their technology can provide not only the needs of the donor services, and various research laboratories, which are in dire need living tissues for experiments. This can reduce the need for laboratory animals, which is very often criticized in the last several years.
