  • 3D printing could lead to printed ‘smart materials’ with geometries that are nearly impossible to produce using other methods, with more research.

The medical 3D printing market is forecast to grow from just over $2 billion in sales in 2022 to $4 billion in 2026 at an annual growth rate of 21 per cent as it is offering new opportunities for personalisation and small-batch production of complicated parts.

Ashley Clarke, Medical Analyst at GlobalData, said that: 3D printing can be used to create custom prosthetics and implants to meet the individual needs of a patient, improving functionality and patient comfort.

“3D printed surgical guides can also aid surgeons performing joint replacement, spinal, and other complex surgeries, leading to improved accuracy and precision during procedures, increased success rate, and reduced recovery times.”

Greater design freedom

The 3D printing revenue in medical sector has been steadily increasing since 2018, due to its increasing applications in orthopedic, dental, interbody, surgical, and personalised devices, allowing new designs to be created at a fraction of the time and cost. This can help accelerate the development process for new devices.

 “Unlike traditional manufacturing techniques, 3D printing offers greater design freedom and has little to no additional cost for increasing complexity of a design. Devices with intricate structures and internal cavities are now possible to manufacture,” Clarke said.

Moreover, he said that design iterations can also help to reduce components, weight, and cost, which is perfect for creating lightweight, compact medical devices with internal functionality.

More new use cases

With more research, Clarke added that 3D printing could also lead to printed ‘smart materials’ with geometries that are nearly impossible to produce using other methods. ‘Smart materials’ respond to stimuli in their environment, such as heat, moisture, or sound, and are promising for medical applications as they can enhance current devices with new properties and improved performance.

Prosthetic limbs with built-in sensitivity, self-expanding stents, self-healing joint replacements, and drug delivery devices that respond to infection are just some of the potential ‘smart’ devices.

Though still far from commercial production, research and design of these devices can benefit from the customisable, small-batch, low-cost, and design freedoms that 3D printing allows.

 As investment in 3D printing continues to grow across all industries, Clarke said that the number of companies with 3D printing software, hardware, materials, and services increases.

“This will accelerate the decentralisation of medical device production and improve device accessibility and distribution.  As the technology continues to evolve, we can expect to see more even more innovative and exciting medical applications.”
