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. So thats been all weve been equaled up in the, enables those to print the layers of living materials and thats my logical material. Teeth which are very complex Material Properties in all fixed lies. And for the whole phone, cutting the ones that we now have you possibilities and file medicine complaint can hopefully print complex organ structures in the future using 3 d bio printing of the key to all the bio printing thats for the bottom. 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 therapeutic 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 trial blazes is us search and talk to Anthony Atalla in 2011 a 3 day printed a kidney. Does the organ is measured using m r i scans the daughters then use to create a 3 day model which has been sent to the printer. The printer manufacturer is the model layout by layoff, from living cells all as shown here from plus to race, such as noting and Trend 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 it 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 should offer insight into how it functions. It will probably still take some time before 3 de 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 broad bought a cop made from synthetic material. Race, such as at the Massachusetts Institute of technology in the United States have developed or 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 robotic caught can mirror a hot date of the patient. Researches one to hone in on how the patients thought is contracting. The robotic 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. Riven bands and his team of developing a new procedure whos speaking and faith isnt in artificial vessels or an age or dream and surgery from the actual content of the cardiovascular surgeons. You inevitably 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 hearts bypass or to bypass and the leg researchers have been working for many decades. Now im creating by artificial vessels in the land. Yep. So standing level, it would enable us to help perform a bypass and patients that dont have the necessary part of the material. I didnt expect them to bypass on people to put the Research Teams idea. A print, a civil tenuously presses to liquids to create a flexible, to made of bio materials. Thats roughly 30 centimeters long. One of these liquids is called by a when its a positive organic. Think thats enriched with even investigative cells. Its guys, this is how genetic material made from brown l. A non drawing back to the salt United States. So as country bind well to it, thats why we add peptides which are small pieces of proteins that can be found in the human body like college and you need the purpose of the know bind to these peptides cubic. Even the peptides can also send signals to the sales forces so that they feel comfortable and can survive and reproduce and bianca after and initial phase using standard straight print is. 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 look at selective im. This may look relatively simple, but it actually requires fine shooting a lot of different parameters and power allows the also in one challenges that bio into it does not have no technic properties. So heres whats missing. In other words, it behaves differently from typical liquids becomes more solid under pressure. But just means we need to equip the printed resistors here to ensure a uniform flow of the by a wink, mcginnis, who move into most a few instead of allies. Its all incredibly delicate and precise work, so its no surprise that the researches have carried out countless test prints. One challenge, the entire structure needs to have a consistent thickness for this evening. But if you take a look at this bypass and you can see how much it sends out within the site, as long as of yes and on the other 2 sides, you can see that its quite sick on the wrong side, right . So it wont hold up on those are the more symmetric, the structure, a stronger the circular structure, the more stable it will ultimately be was, was us. Thatd be the best source of the artificial bypass cross supposed to be as uniform as possible so that they can function inside the patients the decades of the printing. The new structures must mature in a nutrients solution of 37 degrees. For a few days. We usually print at Room Temperature, but keeping the cells at Room Temperature for a long time can be detrimental to the cells you can send in less than the young woman. So we print using this substance we, im a vice and then we place them in san to bio reactive, where the culture is kept up 37 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 sleet 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 by a chips the need for animal testing could soon be reduced. The cells on 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 many 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 channels supplied with f, nutrients and active agent pot live. Uh, excuse me, cells can be grown onto the chip or printed on the slide. Using boiling sensors allowed assign system monitor the condition of the cells home and ship. Many of the bar trees have also started using coaches from multiple organs on the same ship, reducing the number of tests. Today, there are even chips with complex 3 dimensional cell structures, which allows for more precise testing. 3 d 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. A bio for tool could directly print by material until opens and one day it could be deployed inside the human body. We can directly deliver multiple in the lay on the table inside the main body, the quite the coloring, melvin, tennessee. They have to make well material and outside of the body. And then itll go to the lady, the material to have to be quiet when says re a 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 repair them, often injury. So this is a larger version of our 3 d ball printer. We have this is basically use you to, to live up on materials to the engine 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 top, 2 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 incisions 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, especially nifty fi can be utilized on one set of co device. They can both form the and co subject safeco for seizure and therefore they can do more to sit and tie up the kinds of timble inside the bodies. I think actually on the call on kind of sense, 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 donors. Would you donate your organs or do you say 3 d printed organs as the way of the future . Let us know.
