In the past decade, 3D printing has revolutionized many industries, prosthetics and orthotics being no exception. This tech isn’t just a cool innovation; it’s a game-changer, making prosthetics more accessible and personalized than ever before. What’s better than never-before-seen opportunities for patient care?
In this blog, we’ll dive into the history of 3D printing in prosthetics, its impact on the industry, and how this game-changing technology will continue to transform prosthetics.
History of 3D Printing and Prosthetics
The beginnings of 3D printing, also known as additive manufacturing, date back to the 1980s. However, it wasn’t until the 21st century that it began to make waves in the medical field.
3D printing was initially used for creating prototypes and models for surgery—think of it as a high-tech blueprint for doctors. Soon, people began to realize the potential for more complex applications
In the early 2000s, 3D printing was being used for dental implants and custom orthodontics, which was a big deal because it showed how this tech could be personalized. Then, in 2013, the first FDA-approved 3D-printed prosthesis was created.
Since then, we have enhanced traditional prosthetic limbs by integrating 3D-printed components and can streamline certain aspects of the manufacturing process. These advancements often lead to faster production times and make prosthetics more accessible, specifically for patients in remote areas. This shift has made prosthetics more accessible to those in need, marking a significant milestone in the evolution of medical devices.
The Impact of 3D Printed Prosthetics
Healthcare Accessibility
While prosthetic accessibility isn’t the only benefit of 3D printing technology, it is one of the most significant ones. 3D printing has significantly improved access to prosthetic limbs for patients around the world.
Traditionally, prosthetics are costly enough to be inaccessible to many people, especially those in developing countries. In fact, they could cost anywhere from $5,000 to $50,000. This is a steep price tag considering these devices typically require replacement on a semi-regular basis.
Product Quality
When it comes to prosthetics, quality is everything. These aren’t just devices; they’re extensions of someone’s body. 3D printing allows for super precise control over the manufacturing process, resulting in prosthetics that are durable, light, and, most importantly, functional.
Innovations in Prosthetic Sockets
One of the most critical components of a prosthetic limb is the socket, which is the rigid outer part that connects the prosthesis to the body. With 3D printing, sockets now offer improved adjustability, allowing for specific behaviours in different regions (e.g., soft, firm, or rigid) without affecting the overall design. This means that the user benefits from enhanced comfort and fit!
At Hodgson, we use nTopology for topology optimization, which helps reduce weight in these sockets, making them lighter without compromising strength.
Advanced Liners for Comfort
The liner—the comfortable inner part of the prosthesis—has also seen significant advancements due to 3D printing. 3D-printed lattice structures introduce new compression behaviours, which means newer, 3D-printed prosthetic legs can provide region-specific cushioning tailored to the user’s needs.
Although opportunities for improved breathability are still being explored, the ability to investigate these aspects in detail marks a substantial leap forward.
Hodgson is also working on a pressure-driven design project in collaboration with SFU, with the goal of further enhancing the comfort and functionality of these liners. This project is currently in the R&D phase, and we’ve documented our progress in a blog post on our R&D timeline.
Custom Cosmetic Covers
Cosmetic covers, which give the prosthetic limb a more natural appearance, also benefit from 3D printing. We can now create limb-matching 3D-printed cosmetic covers by mirroring a scan of the user’s leg. This results in a prosthesis that closely resembles the other limb. It may not seem like a big deal, but this likeness not only improves the aesthetic appeal but also boosts the user’s confidence.
Innovative Components and Wearable Technology
3D printing has opened up unique opportunities for designing prosthetic components that offer enhanced adjustability, cosmetic options, and even the integration of wearable technology.
Digital design programs can handle the data produced by wearable tech, allowing us to take full advantage of this information to create prosthetic limbs that are more in tune with the user’s needs. This eliminates the need to interpret data manually and turn it into plaster modifications, streamlining the whole prosthetic manufacturing process.
Personalization Standards
One of the most exciting things about 3D-printed prosthetics, as you can probably tell already, is the level of personalization they offer. Unlike traditional prosthetic limbs, which often require a lot of tweaking to get the right fit, 3D-printed prosthetics are designed to match the exact measurements and needs of the user right from the start.
And there’s more! People can also choose various colours, designs, and other aesthetic features that help them feel more confident and comfortable. It’s not just about function—it’s about making the prosthesis feel like a true part of the person using it.
Challenges in 3D Printed Prosthetic Limbs
Despite the many advantages of 3D-printed prosthetics, there are challenges that need to be addressed.
One of the big ones is durability. While 3D-printed prosthetics are improving, there’s still work to be done to make sure they can withstand daily wear and tear, especially in more extreme conditions.
There’s also the regulatory side of things. The FDA, Pharmacare, and other regulatory bodies around the world are still figuring out how to handle 3D-printed medical devices. It’s a bit of a balancing act—ensuring these devices are safe and effective while not shutting down innovation.
Looking at the Regulatory Landscape for 3D Printed Medical Devices
Navigating the regulatory landscape for 3D-printed medical devices is important to make sure these innovative products are safe, reliable, and effective for patients. In the U.S., the Food and Drug Administration (FDA) has been leading the charge in setting guidelines for 3D printing in the medical field.
Essentially, the FDA looks at the design, manufacturing process, and materials used in these devices to make sure everything meets their strict quality standards. This includes validating the software used to design the devices and the 3D printers themselves.
On the global stage, different countries have their own rules, but many of them follow similar principles to what the FDA has put in place. Additionally, there are international standards, like ISO 13485, which offer guidance on maintaining quality across the board, no matter where the devices are being made.
Insights Into the Future of 3D Printed Prosthetics
The future looks bright for 3D-printed prosthetic limbs. We’re seeing ongoing advancements in materials and printing techniques that promise to make these devices continually better—stronger, lighter, and more durable. As the technology becomes more widespread, we can expect to see even more innovation in terms of design and functionality.
There’s also exciting potential in bioprinting—the process of printing with living cells. This could one day lead to the creation of tissues or even organs, opening up entirely new possibilities in medical care.
