Various exterior shots of Cornell campus and students walking \u003cbr/\u003e3D printing technology is helping scientists in the US make live body parts.\u003cbr/\u003eIt could mean that in the future if you need a replacement ear, for example, you simply have to print one.\u003cbr/\u003eThis technique has got the medical world listening.\u003cbr/\u003eThe 3D scanner at Cornell University is compiling an image of this patient's ears. \u003cbr/\u003eIt's been in use for almost 20 years, and was originally developed to scan a person's head and sculpt their likeness out of wax.   \u003cbr/\u003eIt has a new and more noble calling these days however, thanks to advances at a bio-medical laboratory on the same campus: it is helping scientists grow replacement body parts.  \u003cbr/\u003eThis could mean in the future patients grow their own limbs and ligaments, and could mean less scalpels and invasive surgeries. \u003cbr/\u003eIn the computer graphics department, the challenge is not getting the information about the human body, it's creating something out of that information that drives the scientists. \u003cbr/\u003eHurf Sheldon explains: \" So you could have all the information you need to duplicate yourself on a micro-dot.  But the question is: we can get the data... so it's turning it back into something that's the problem.\"\u003cbr/\u003eBioengineers are using success in 3D imaging and printing technology to print body parts using living cells that can grow inside the body once the transplant is complete.\u003cbr/\u003eScientists at Cornell University are taking reconstructive and transplant surgery into the future using a combination of 3D imaging technology and 3D printing.   \u003cbr/\u003eThe real breakthrough however, is that the bioengineers have devised a way to print certain 3D body parts out of living cells.  \u003cbr/\u003eAfter the ear - or remaining ear - is scanned, then the living cartilage cells are \"printed\" layer by layer using a collagen solution that hardens and supports the cells as they multiply. \u003cbr/\u003eThey say this will soon make it possible to print replacement parts for people, customised to their exact specifications and even using the patient's own cells to avoid immune rejection issues.\u003cbr/\u003eTraditionally, cartilage is taken from the patient's ribs, or other parts of the body, and a second surgery can increase the risk of complication. \u003cbr/\u003eBecause these cells can be grown from the patient's own tissue samples, chances of rejection are decreased.\u003cbr/\u003eDr. Larry Bonassar, Associate Professor of Biomedical Engineering explains: \"The idea of being able to use inks for example, that are alive, is really what takes this to the next level.  What is coming out of the printer is alive when we print it, it is alive when we grow it in the incubator, and it's alive when it goes into a patient.\"\u003cbr/\u003eAdvances in medicine have enabled us to scan the body, and understand the complexity of our organs through imaging technologies like Magnetic Resonance Imaging (MRI) and Computed Tomography (CT or CAT scans). \u003cbr/\u003eThe opportunity to scan and create body parts from with living cells offers new possibilities in medicine. \u003cbr/\u003eResearch student, Rachel Nordberg explains what makes this so exciting: \"It sounds� it does sound like science fiction, it does sound crazy,  but when you actually think about the medical applications to it� It's helping someone� instead of just putting an artificial piece of metal or plastic into someone's body, you are actually helping them use their own cells to make a body part, which I think is a fantastic opportunity for medicine.\"\u003cbr/\u003eThis could mean bespoke body parts to suit each and everyone of us explains Dr Bonassar. \u003cbr/\u003e\"Just more broadly, this could really be the first example of how we could use tissue engineering technology and medical imaging together to make custom implants for patients.\"\u003cbr/\u003eThe printed ear is incubated for about a month. And then it's ready to be implanted directly underneath the skin where it will get nutrients directly from the blood and continue to grow with the patient.\u003cbr/\u003eResearchers at Cornell say the process could be used to reconstruct ears for children with birth defects, and for people who have lost ears through injury. \u003cbr/\u003eThe scientists say that ears are only the beginning.  \u003cbr/\u003eThe same process can be adapted to other cartilaginous structures and could eventually reproduce bone and soft tissue. \u003cbr/\u003eThese bodyparts can be created on a computer , unique to each patient. \u003cbr/\u003eScientists imagine a point in the future when doctors can keep a record of a patient's body scan, and then if parts need replacing in the future, they can print out an exact replica.  \u003cbr/\u003ewacky\u003cbr/\u003e\u003c/span\u003e\n\u003c/div\u003e\n\u003cdiv class='action-container flex justify-between'\u003e\n\u003cbutton aria-expanded='false'
