What you're seeing here is a fully personalised heart sensor. New 3D printing technology allows bioengineers to create realistic models of a patients heart that a stretchy sensor can then be built around. The result of this is a life-saving sensor that's a perfect fit the for the user, as everyone's organs are different.
This life-saving technology will help ensure people with delicate tickers get help right when they need it most.
3D printed blood vessels
Engineers are currently working on improving medical 3D printing technology to allow the mass printing of human organs for transplant. This work includes the creation of viable blood vessels that could be used in the human body. A recent breakthrough has even allowed Chinese scientists to successfully implant these vessels in monkeys.
These sorts of medical advancements could see the need for transplant waiting lists negated and people's lives being saved in much more cost-effective ways.
3D printed heart valves
Heart disease is a problem that affects people from all ages and walks of life. A simple valve defect can be easily fatal if left untreated. Current treatment for adults involves the use of prosthetic valves, but these aren't suitable for everyone - especially not children.
In steps 3D printing, with the creation of precise bio-printing technology that allows the fabrication of living heart valves that are a perfect fit for the patient. This bio-printing system ensures doctors can create a patient-specific heart valve that's more likely to take and keep the user alive.
3D printing in the medical field isn't just limited to valves, vessels and body parts. One company is also using these techniques and technologies to create micro-tools capable of performing accurate and intricate surgery with less risk. These minuscule surgical instruments include forceps less than a millimetre in diameter and allow for the creation of a range of new tools to help surgeons operate safely on a daily basis.
Complex surgical tools
Other companies are using 3D printing to create complex surgical tools too. Here, the Dragonflex Micro is a miniaturised tool designed to be reliable and precise even with components on such a small scale. Impressive that these tiny 3D printed tools are capable of saving lives.
3D printing is helping people on the outside too. The development of these sorts of exoskeletons helps disabled people by giving them support where they need it most. This enables them to move in new and wonderful ways that their body would never normally allow. Children with congenital diseases are suddenly capable of moving around like their friends and joy is brought to their entire families via simple printed technology.
When an 83-year-old woman was faced with issues of a chronic bone infection and doctors believe that her age made reconstructive surgery too risky, they turned to 3D printing. This newly printed jaw was the result. A complex model that needed to include joints for movement as well as cavities to encourage muscle attachment and the regrowth of veins and nerves, it was initially a tough design. The result, however, was a success and the woman was able to leave the hospital just four days after the operation with a new jaw intact.
Real bone from a 3D printer
After a CT-scan of a patient, biomedical engineers print a perfect fit replacement to repair or replace broken bones or problem areas. This 3D printing is slightly different from others on our list as it makes use of printing in calcium phosphate - the main constituent of natural bone. Once the 3D printed material is grafted to the patients own bone, the two natural materials bond together and "unify" over the coming months. CT-Bone gives the best fit and best results in this sort of application.
Flexible bone implants
Also referred to as "hyperelastic bone" this newly developed technology is basically a kind of 3D printed ink that can be used to form flexible bone implants in any shape, size or form. These new implants are embraced by the body and due to their flexibility, they also allow for infiltration of blood vessels and slowly turn into natural bone within the body.
Scientists at Princeton University successfully created the first functional 3D printed ear that's capable of hearing frequencies beyond that of the average human ear. These are the beginnings of the future of bionic ears. They represent not only possible replacements for those in need but perhaps the future of augmented human beings.
Traditionally skin grafts are taken from other parts of a patients body to help replace burnt, damaged or diseased skin elsewhere. This practice may soon be a thing of the past as scientists have managed to print living tissue that could feasibly be used as a replacement where necessary.
So far they've managed to print and grow ear, bone and muscle structures into fully functional tissues that include blood vessels too. The aim is to be able to grow replacement tissue and organs to help deal with medical shortages and save lives across the world.
Advancements in stem cell research mean that we're reaching a point where it's nearly possible to load living cells into a capable machine to 3D print tissues, organs and more. All of which are capable of being used effectively inside the human body.
Medical researchers have successfully designed a printer that's capable of printing kidney cells into a three-dimensional kidney prototype. Although still in early stages, this technology could mean that in future doctors will be able to use patient data from CT scans to create computer models of their organs and print perfect replicas.
3D printed teeth
If you're worried about losing teeth, you might not need to worry much longer. Soon dentists might be able to print you a replacement. The news gets better too as this 3D printing tooth technology makes use of antimicrobial plastics which fight off bacteria and help improve oral hygiene.
Facial reconstruction surgery is often complicated as patients will have to deal with issues of tissue rejection and a lifetime of immunosuppressive therapies to prevent the new bone being rejected. Biomedical engineers are getting around this issue with 3D printing of replacement noses to help those in desperate need of reconstructive surgery. This technique is not only more successful, but allows a better fit for the patient as the printing can create a nose that's a shape for them.
3D printed medication
3D printing isn't limited to new body parts and skin cells, it's also being used in the creation of medication. This epilepsy drug is being mass produced using 3D printers in a way that allows easier swallowing for those who need it. Over time, 3D printing will likely lead to a reduction in the production costs of medication and hopefully, a reduced cost to the end-user too.
Traditional treatment for deep burns is to cover them with healthy skin from other parts of the body, but where extensive burns cover the whole body there often isn't a viable solution.
Scientists have broken new ground with technology that's capable of printing skin cells to help in situations like this. This printing also takes into account the fact that different kinds of skin cells are used at different depths, so the deeper the burns the more the printed skin needs to change to cope. Stem cells are also being used here to help with the healing of wounds and speed up the recovery process.
Medical models to help surgeons
3D bio-printing techniques are also applied to the creation of replica body parts that can be used in the training of new surgeons. Something like heart surgery, especially on children, can be extremely difficult, delicate and intricate. Being able to practice is an important part of successful surgery and so this 3D printing of test organs will help save lives before surgery even begins.
What you're looking at here might be the start of 3D printed prescription lenses, though it's certainly in its early stages. Although these printers are capable of printing lenses, there is still a lot of work that needs to be carried out in the form of polishing and sanding to make the lens usable. Still, it's yet another impressive use of 3D printing that we're excited to see progress.
A college student, low on cash but not lacking in ideas used 3D printing technology to create his own orthodontic braces after scanning his teeth, making and casting moulds and more. Impressive work that resulted in much straighter teeth for the young man.
3D printed skulls
A young woman from the Netherlands suffered from a chronic bone disorder which led to an increase in the thickness of her skull resulting in painful headaches and issues with her eyesight. Surgeons used 3D printing techniques to create a replacement skull which was successfully implanted in her head effectively saving her life while also restoring her sight eliminating the headaches too.
