Printing Our Three-Dimensional Future

With the emergence of 3D printers into mainstream markets, what the devices actually do seems to matter less than what they will do, or could be made to do, in the future. Will they create a crisis of unregistered, undetectable firearms? Or will 3D printers become such a life-saving a medical necessity that a century from now, consumers will regard the technology as unremarkable as the current practice of casting broken bones?

I don’t have the answers. But from a health and safety perspective, I think 3D printing is among the most profound opportunities we as a society have to alter the future. It’s hard to believe that it all starts with a single drip of liquid plastic…

How 3D Printing Works

Despite the hype, 3D printing technology isn’t new. A 3D printer existed as early as 1984, according to PC Magazine. At its most simplistic, the technology compares to the process of printing a two-dimensional document from your home or office computer. Instead of flat ink, devices “print” layers of a substance – typically plastic, but alternatively metal or biological materials – to create a three-dimensional shape.

As a whole, 3D printers have become more affordable and less technically demanding so that some businesses and hobbyists can attain and operate the once mysterious and rare devices. Prospective users can purchase 3D printers from mainstream retailers like Staples and Amazon.com, according to science and tech site Singularity HUB for around $1,300 or less, and some tech sites report certain models going for as little as $200 to $500 – not so different from the cost of early P.C.’s. With companies like Microsoft jumping onboard the bandwagon by announcing the integration of 3D printing support into upcoming products, it’s easy to anticipate a scenario where everyone has access to 3D printing just as they can create documents with little more than a click.

But the question that’s got techies deep in thought and media, government officials, and the public on edge is what, exactly, will people use the technology to accomplish?

Printing Medical Miracles, One Tissue at a Time

As startling as the prospect of an influx of cheap, unregistered, undetectable guns may be, 3D printers also have life-saving possibilities. The technology can fulfill an array of medical functions, from training purposes to treating injuries. In the future, doctors intend to create entirely new tissues and even organs with the help of 3D printers. The potential for saving, extending, and improving lives is nothing short of awesome.

“Practicing” Medicine

Doctors study human anatomy and physiology intensely during their training, but no matter how thoroughly they memorize diagrams, they can never become completely familiar with the diseased internal organ of a particular patient. Imaging tests are certainly a help, but when it comes to operating on a real damaged heart, there’s more risk than either doctors or patients are comfortable with.

Already, 3D printing has made great strides in changing how surgeons prepare for these high-risk surgeries. Realistic replicas of individual human organs allow doctors to practice difficult techniques on the heart and other vital organs before opening up the patient. This means less risk to patients, as complex surgical techniques will have already been put through a trial run. In Iowa, some doctors working in such specialties as orthopedics, neurology, and cardiac surgery currently are using 3D printed organ prototypes to prepare for the demands of real surgeries, Digital Journal reported. The prototypes are based on actual CT scans of particular patients. More training equals less likelihood for complications – and in an already risky surgery, that means everything.

Will Signing a Cast Become a Thing of the Past?

As good as modern medicine is, there are a few practices where it seems like there’s got to be a better way. As anyone who has ever fractured a bone knows, casting a broken bone is one of those practices. Often, patients with traditional plaster or fiberglass casts complain about the itchy texture, the size of the bandage restricting what clothing they are able to wear, and the challenges of trying to bathe without getting the cast wet.

This bulkiness and inconvenience drove a New Zealand designer to develop a lightweight cast that can be custom 3D printed to fit users’ bodies precisely, Gizmagreported (check out the pictures here). The cast is made of plastic and has an almost lattice-like appearance, leaving much of the body part exposed to reduce itching. Unlike the hefty plaster and fiberglass casts of old, this new design could get wet without complications and would be thin enough to fit inside clothing easily.

Research suggests 3D printing also can help build new bones. By using 3D printers to create biodegradable framework to simulate bones and cartilage and then strategically placing actual human cells capable of regeneration, doctors and researchers could make “fake” body parts that would eventually become a real, permanent part of the patient, Yahoo! News wrote. Noses, ears, and jawbones are just the beginning. The idea – at least in theory – is better than transplants, which can be rejected, or implantable devices, which can cause any number of adverse effects. While the technology hasn’t reached the stage of human trials just yet, it seems to be on the horizon.

The End of Transplants?

Each day, 18 Americans die while waiting for some type of transplant,OrganDonor.gov reported. Transplant procedures are difficult, from locating a matching organ to performing the surgery to recovering from the trauma of the operation. Sometimes transplants fail. Sometimes the recipient’s body rejects the foreign organs. The resources are scarce, and because they can only come from deceased humans who have died in ways that did not damage the organs, there has never been an ethical way to increase the number of resources.

Until now.

Scientists have already been able to use 3D printing with biological materials to create synthetic human tissues, some of which can contract like muscles and carry electric signals like those needed to run our bodies, The Los Angeles Times reported. The hope, throughout the medical community and among patients and family members, is that 3D printing technology could eventually grow entire functioning organs, either synthetic or through real patient cells. Imagine a scenario where there was no waiting list to determine whether or not a patient would survive –in which the rejection of an organ is unheard of. Not only would 3D printed organs save lives, but they could cut huge costs to the healthcare system. Instead of long-term dialysis, kidney failure patients could just get a new kidney. Diabetic patients could get a new, perfectly functioning pancreas. The possibilities seem endless.

I can imagine the implications that medical 3D printing could have for the clients who have turned up at our office, their bodies battered and broken in accidents. A client who lost his lip in a dog bite could have his face made whole again, with a lip grown from his own cells. For a car accident victim whose arm suffered such a forceful impact that the bones broke in half, these new techniques could result in a quicker, less inconvenient recovery. Babies born with birth defects could have replacement body parts made from their own cells that could grow with them. And for those who suffered internal organ damage, or nerve damage, or traumatic brain injuries – will 3D printing finally make us capable of fully healing these injuries that, until now, have been permanent?

Like nearly all technologies, 3D printing can be used for good or for harm, but that doesn’t mean we have to dread it. Rather than living in fear of the dangers that could theoretically happen, let’s remember the opportunities that this new technology provides to help literally hundreds of thousands of people – if not more – live longer and fuller lives.

Troy Dayon, President of Stanley Healthcare and Stanley Access Technologies, explains how tech can help carers support an aging population

Stanley Healthcare provides technology solutions for caregivers, whether they are in a hospital, a care home, or at home. Here the company's President Troy Dayon explains the challenges carers face and what role technology plays in care for the elderly. 

The healthcare workforce is shrinking while the population is aging. How can this be addressed? 
Not only is the healthcare workforce shrinking, but the industry is facing the issue of overload and burnout among healthcare professionals. 

One major approach to address this is to help each caregiver to accomplish more – not by pushing them harder but by focusing their attention on the things that matter most, harnessing technology such as AI and machine learning. 

This technology provides caregivers with information on what care is needed, and which patients or residents to focus on first based on risk or acuity. The insights that it provides can help caregivers to be more efficient and address issues that would usually require more of their time, such as critical asset location, which takes time away from giving the care where it’s needed most. 

What do healthcare providers need to do to address clinician burnout? 
It is key for healthcare providers to understand the setting and the specific environment in which clinicians have been working. Many hospitals across the globe reconfigured entire wards to treat COVID-19 patients, and for more than a year, clinicians have been working in crisis mode. 

They need the opportunity to return to regular, sustainable routines, supported by technologies that help make them more efficient, but also more fulfilled because they maximise time with patients, applying their hard-earned education and experience to work at the top of their license.

In aged care, the experience of managing a highly contagious and deadly virus has reinforced the need for a proactive approach to managing the health of residents. Caregivers need predictive tools like the Foresite solution to help them understand which residents are at greatest risk, so they can focus their efforts where they can have the most impact. 

How can technology support older people? 
AI-based technology such as Foresite harnesses a range of passive monitoring technologies to develop a baseline profile of a resident in aged care that highlights changes in health or behaviour. This information can help caregivers see where and when they need to spend their time, identifying heightened risk for falls and early indication of heart issues and even infections. 

In fact, the technology has been shown to accurately predict events like falls, which allows intervention prior to an event occurring, rather than just automating routine processes.

Beyond this, connecting caregivers remotely to seniors to provide efficient care outside of traditional care settings is crucial. During the pandemic, there was a marked increase in the use of telehealth and remote monitoring of vitals, medication management and daily health. 

These technologies fill a major gap in healthcare delivery: care for patients once they’ve been discharged from hospital, or for seniors who need some level of care but don’t need to be in an aged care home. By caring for people effectively in their own homes, we can help reduce the burden on hospitals from readmissions and leverage the expertise of aged care organisations beyond the confines of the four walls of the facility. 

A lot of care is in fact delivered by unpaid carers. How can they be better supported with tech?

The remote monitoring technology that professional caregivers have access to can, in turn, also provide information and support to unpaid caregivers. For example, helping ensure a loved one is taking their medication, or knowing when they might be experiencing a change in health that can put them at risk. 

Human observation is inherently limited, no matter how often you see a loved one, and you can’t always rely on what a senior says about themselves. It’s very common that they downplay problems, because no one wants to be a burden or relinquish their independence. 

Remote solutions that connect family to an older relative help increase safety and wellbeing for the senior and reduce the burden on caregivers. They also make possible care decisions based on facts. At some point, a senior may need to transition to an aged care setting, which is often a difficult family conversation. This is an area where we can offer support to unpaid caregivers – reassurance during what is typically a very stressful period for the people providing that care. 

In Japan several large hospitals are deploying robot nurses. Is this a potential solution? 
I think the best path for robotics in healthcare is to focus on the root problem. It’s about dealing with a limited number of caregivers for a population that’s rapidly aging. Robotic technologies offer solutions that support the human healthcare providers with the information they need to make better and faster decisions about care. It’s about convergence and use of technology rather than a specific solution such as a robotic nurse.

This technology could be in the form of AI and machine learning or a robotic agent for routine administrative tasks. Removing low-value activities that distract caregivers from giving care is a key focus when it comes to robotics in healthcare. This automation can free up time for caregivers to spend more time with patients while optimising workflows. 

Robots in this sense don’t replace humans. They are leveraged for what they do well – repetitive routines done with speed and precision – while humans are given the time and space to deliver what ultimately we all want: human-centered care.
