The Future of 3D Printed Medical Devices

A study published last month by Additive Manufacturing Research predicted that the 3D printed medical device market will reach $16.5 billion in revenues in 2034 growing from $4.5 billion in 2023 at a 10-year CAGR of 12%. The report noted that over the past two decades, the use of 3D printing technology has significantly impacted the healthcare sector by facilitating the production of personalized medical devices, reducing development costs, fostering innovation in advanced devices, and improving accessibility to prosthetics. The greatest areas of growth were predicted to be in the prosthetics, audiology, and dental field.

3D printing technology has been a specialized discipline at Prodigy and recently medical devices have been a great area of exploration for several reasons. Firstly, 3D printing excels at producing parts in quantities that are ideal or near ideal for medical applications, where complex, custom-made devices are often needed. This is particularly relevant for patient-specific prosthetics and dental implants. Secondly, 3D printing dramatically reduces development cycles compared to traditional manufacturing techniques. This allows for faster iteration and quicker time to market for new medical devices. Additionally, creating patient-specific geometries based on 3D scans is a game-changer, enabling a new level of customization and fit for prosthetics and other medical devices. Furthermore, advancements in 3D scanning technology and the increased accessibility of user-friendly CAD tools are empowering engineers to design ever-more intricate medical devices. Finally, 3D printing shines in producing complex geometries, including manifolds, organic shapes, and ergonomic designs – features that are highly desirable in many medical devices and applications. These factors combined are propelling 3D printed medical devices towards a future of wider use and greater impact on patient care.

This new frontier is not without its drawbacks. Beyond the well-known challenges of sterility, material properties, and FDA regulations, there are some lesser-understood hurdles to widespread adoption of 3D printed medical devices.  One such challenge is post-processing, which can be surprisingly time-consuming and labor-intensive.  3D printed parts often require additional steps like cleaning, smoothing, curing, and polishing to meet the exacting standards needed for medical applications.  This adds extra time and cost to the overall manufacturing process.  Another challenge lies in achieving material properties that match those of traditionally manufactured devices.  While advancements are being made, 3D printed materials may not always exhibit the same strength, durability, or biocompatibility as those produced with established methods.  This can limit the range of applications suitable for 3D printing in the medical field and why it is critical to understand the latest technological and material developments in the 3D printing field while incorporating the technology.

While prosthetics, audiology, and dentistry are certainly established growth areas for 3D printed medical devices, as identified by the report, their potential for explosive growth may have matured. Many companies have already formed partnerships and developed specific technologies in these fields, particularly dentistry.  However, the future holds promise for even wider adoption in other medical sectors.

Here are some areas where we might see significant growth:

• Medical devices and robots: 3D printing’s ability to create complex, lightweight, and customized parts makes it ideal for the next generation of medical devices and robots. Imagine customized surgical instruments tailored to a specific procedure or intricate components for robotic assistants.
• Surgical tools: The ability to produce complex, single-use surgical tools with 3D printing could revolutionize operating rooms. This could lead to more cost-effective, personalized, and efficient procedures.
• Imaging equipment: 3D printing’s design flexibility can be leveraged to create customized phantoms for medical imaging calibration and training.
• Consumables (single-use components): 3D printing can produce specialized, single-use medical components that are perfectly suited for a specific task, potentially reducing costs and waste.
• Patient transport: Customizable splints, braces, and other patient support structures could be created quickly and efficiently using 3D printing technology.

The medical field, with its need for both some level of production volume and patient-specific customization, presents a perfect environment for 3D printing to flourish.  As the technology matures and regulations evolve, we can expect to see 3D printed medical devices playing an even greater role in improving patient care.
