Also known as additive manufacturing, laughter has been in use an industry and for a number of years up yet, it basically means building complex objects layer by layer hiding young and a few years ago. And this trend also made its way into the field of biomedicine told us in all weve been naked up in the enables those to print the layers of living materials. And thats my logical material. Teeth which are very complex material properties. These things all fixed lives and for the world all phone cutting, the ones that we now have new possibilities and file medicine complaint can hopefully print complex oregon structures in the future. Using 3 d bio printing of the key to all the bio printing thats for the bar printing had sustained. So science is can actually print organs using living cells. Thats pretty incredible. In 2022, the 1st 3 d printed it was transplanted into a volunteer in the United States. But that was the last we heard. We reached out to the company 3 day by a therapeutics several times for an update on the current clinical trial. Without any luck, but this much is clear. The race to manufacturer functioning organs using 3 d printers has been going on for years. First attempts to fly printing artificial organs were made over 2 decades ago. One of the trail blazes is us surgeon, dr. Anthony atalla. In 2011 a 3 day printed a kidney. The us, the organ is measured using m r i scans the data is then used to create a 3 day model which has been sent to the printer. The printer manufacturers the model layout by layout, from living cells, all as shown here from plus a race such as noting am Trent University develop basically about using a 3 d printer in 2021. It looks deceptively real, but its actually made of synthetic materials. Its supposed to help train doctors to recognize live a cancer. In 2020 to 3 day systems and United Therapeutics presented a 3 day printed long structure. This synthetic creation should help regulate gas exchange the way healthy lungs do. Animal testing, shoot off an insight into how it functions it will probably still take some time before 3 day printed organs will actually be able to replace traditional organ donations. But this technology is already proving to be very useful in medical research today. Like this 3 d printed book bought a copy made from synthetic material. Race such as at the Massachusetts Institute of technology in the United States have developed a wrote, bought a car using a 3 d printer. The replica is supposed to emulate the functions of the patients individual heart researches 1st create a 3 dimensional computer model using data from the patients hot. Its made up of soft, flexible, synthetic materials. The artificial heart is wrapped in slaves that mimic a hot date. H one is controlled separately to ensure that it pumps realistically, this way the rug bought a car and mirror a hot date of the patients. Researches one to hone in on how the patients thought is contracting. Robotics is not meant to be transplanted. Instead, its supposed to help doctors better understand the hot conditions of individual patients. And therefore i pinpoint the best treatment very helpful for treating people with hot conditions, but not a solution for patients waiting for an actual hot transplant. Still 3 day by printing can be deployed in other ways. Lots of patients who need a bypass due to block vessels, researches in northern germany, a testing out this idea of vascular surgeon, dr. Ruben bands on his team of developing a new procedure. Speaking and fees isnt in artificial vessels or an age or dream and surgery from the actual content of the cardiovascular surgeon, you and have typically end up in a situation where youre caring for a patient, but dont have any suitable material to use for to bypass and for example, i must, im for a heart bypass or a bypass and the leg on researchers have been working for many decades now. Im creating bio artificial vessels in the line. So standing in level view, it would enable us to help perform a bypassing patients that dont have the necessary bodily material. I expect them to bypass on beating the Research Teams idea. A print, a single tenuously presses to liquids to create a flexible, to made of bio materials. Thats roughly 30 centimeters long. One of these liquids is so called bios and its a positive organic. Think thats enriched with even investigative cells. Its guys, this is how genetic material made from brown out of natural back to the cell generates a step. So as country bind well to it, thats why we have peptides which are small pieces of proteins that can be found in the human body like college and you need to pay the sounds good now bind to these peptides cubic even the peptides can also send signals to the sales so that they feel comfortable then can survive and reproduce and bianca after and initial phase using standard straight printers. The team is now switching to a robot with a specially developed printed one chain. The in the print head contains the boiling, while the other contains calcium, fluoride stabilizes the bypass graft. Lets design. This may look relatively simple, but it actually requires fine shooting a lot of different parameters in parallel. How sort of 11. 00 challenges the bio into it does not have no technic properties. So heres whats missing. In other words, it behaves differently from typical liquids. I think it comes more solid to under pressure. Eva, by this means we need to equip the printing resistors here to ensure a uniform flow of the by a wink, mcginnis, and who move in 1st, the few instead of allies. Its all incredibly delicate and precise work, so its no surprise that the race searches have carried out. Countless test prints. One challenge, the entire structure needs to have a consistent sickness existing. But if you take a look at this bypass and you can see how much it sends out and the size length of yes and on the other 2 sides, you can see that its quite sick and the room size i so it wont hold up on those are the more symmetric, the structure, the stronger the circular structure, the more stable it will ultimately be . What was this . Thatd be the best of the artificial bypass cross i suppose, to be as uniform as possible so that they can function inside the patients the decades of the printing. The new structure is the most mature in an nutrients solution as 37. 00 degrees for a few days. Were usually print at Room Temperature, thats what it is a cell, but keeping the cells at Room Temperature for a long time can be detrimental to the cells, even cell in less than one moment. So we print using this substance, we on the bike and then we place them in san to buy or react to where the culture is kept at 37. 00 degrees. The item is for as many cells to survive the printing process as possible. If everything is going smoothly, numerous green cells become visible under the microscope. In the next lab test phase, bypass graft a being tested in animals. Clearly a controversial ethical issue, but the Scientists Say its necessary. And on that topic, 3 d printing with living cells could actually even help to replace animal testing. For example, when developing new drugs, pharmaceutical labs could use so called organ on a chip models. These devices can emulate how human organs function thanks to buy a chips, the need for animal testing could soon be reduced. The cells on the so called organ on a chip systems biologically, mimic human organs. When they come into contact with active agents, instead of animal testing, researches are increasingly using these kinds of mini labs. It helps them to sun, if substances toxic to the human body or whether they could work as medications. The system basically consists of a microscope slide, at least one cell culture and micro channels. The membrane works as a carrier for the cell culture, while the micro channel supplied with f nutrients an active agent pot live. Uh, excuse me, cells can be grown onto the chip or printed on the slide using boiling sensors allowed to sign system monitor the condition of the cells home. The chip. Many of the bar trees have also started using coaches from multiple organs on the same chip, reducing the number of tests today that are even chips with complex 3 dimensional cell structures, which allows for more precise testing. Friday, printing, using living cells, certainly books, very promising. Of course, it would be even better if we could print cells and organs exactly where they needed inside the human body. And scientists are already making big strides. Check it out. This is an experimental meaning 3 d bias to tool could directly print by material until opens and one day it could be deployed inside the human body. We can directly deliver multiple and they uh, they only table inside. Theyve been bought a quite a car and, and melvin tennessee. They have to make well material and outside the body. And then itll go to the lady, the material to have to be quiet when it says re bunch and ready to quiet last infection. And look last similar to an endo scope. The soft, inflexible robeteck is inserted into the body by the through the mouth and a small, a small skin incision using bio ink. The device can print by material on to organs and tissues, for example, to have had an oft or an injury. So this is a larger version of our 3 d ball printer. We have this is basically used to, to, to live up on materials to the ended side or off of the surgery to facilitate to the healing process. We have a camera located at the tip for the visualization, as we can see right here. And we have one channel at the tip to for the delivery of the materials. And after the fact, we have the control us to control the bending of the printer. And it doesnt lead print, it can also make any decisions and spray water to clean the wounds after an operation in the future. This medical tool could be used for different types of surgeries, including the removal of cancer risk, janice and it basically did defy, can utilize on in one set of co device. They can both form the and course a big safeco for seizure. And therefore, we can do more to sit and tie up the kinds of timble inside the pony, like actually on the call on kind of. So there is so much of groundbreaking Research Going on right now. But what people who are waiting for an organ transplant need the most is more open dont is, would you do a night your organs, or do you say 3 d printed organs as the way of the future . Let us know. And so you next on the have you ever heard the term jump . Ha. Just basically describes how masses of young people are leaving the country to search for better opportunities elsewhere. When skilled work is leave africa, they leave the program a great, great big. Its hard to appreciate the real part of this problem. We sent out our team of correspondence to find some answers this 77 percent in 30 minutes on a z w i. By the ancestors the people are celebrating the return of the belief bronze sculpture stolen during the colonial period by returning the vital piece of their history. Ann coulter also comes home. But when you say that its not enough to us, and 9 few minutes dw, the, the sometimes its hard to find what youre looking for. But weve got something for you. But well tell you the story. We have a getting a visa is more difficult than finding gold hosted to use that for sure. Yeah. And for the future feelings about whats going on in the dentistry. Instead of being discussed across the continent, dw, and use africa every friday on the w. This shadows, these pod costs and videos shed lights on the dog is devastating. Colonial har is infected by germany across and he employed to sports farms and destroy lives. What is the legacy of this wide spread races, depression, today . History, we need to talk about here, the stories, shadows of german colonialism. The. This is the news and these are top stories. German chancellor, all off schultz and other european leaders have ruled outstanding Ground Troops and to ukraine. This follows french president emanuel and that calls comment and nothing is off the table to ensure russia does not win the war. The many of the criminal has worn that sending western Ground Troops would be a dangerous escalation of a german police. Say they have arrested a 65 year old woman whos been on the run for 30 years then you
