IDTechEx explores 3D printing developments in the medical sector

New report examines the ten year outlook of the materials and processes best suited to specific applications of 3D printing, including medical use.

The medical sector is one of the largest spaces where 3D printing operates, with opportunities for implant customisation, educational models, and drug manufacturing. IDTechEx’s report, “3D Printing and Additive Manufacturing 2024-2034: Technology and Market Outlook”, explores the materials and processes best suited to specific applications of 3D printing.

3d printing outlook predictions for the next ten years

3D printed implants

Surgical tools and instruments, intraoperative guides, preprocedural models, and educational models can all be created using 3D printing, alongside medical devices like hearing aids, braces, and prosthetics. 3D printing of implants, such as heart stents and heart valves, is one of the main medical applications for this technology. This approach to creating implants enables customization of size, shape, and structure for a perfect fit.

High temperature thermoplastics, such as PEEK and PEKK, are the main polymer types used across implant applications, according to IDTechEx’s report. The report also covers multiple case studies of 3D printing in medical settings. These include a hip replacement revision surgery, a canine cranial plate in titanium, hearing aids, and ventilator parts.

Biodegradable polymers like PCL and PGA are also being explored for their potential success for temporary implants, around which tissue can regenerate. However, gaining FDA approval for these implants can prove difficult, with IDTechEx reporting that there is still quite a way to go before companies can expect widespread adoption.

3D printed educational models for higher surgical standards

Training medical students with educational models of humans, alongside preoperative models used for mimicking a patient’s anatomy, are two examples of how 3D printing plays a large role in surgical environments.

The benefits of using these models includes the elevation of both surgical standards and efficiency as a result of more care being taken in preparing for operations. Less post-operative complications could be seen as a result, while surgical precision may be improved with additional training possibilities. IDTechEx lists vat polymerization and material jetting as being most beneficial for such applications, as they can achieve a higher resolution and smoother surfaces than with thermoplastic filament extrusion.

Pharmaceuticals and rapid drug manufacturing

The pharmaceutical industry could also benefit from developments in 3D printing, as pills could be manufactured using this technology. Polypills, excipients, nanosuspensions, and hydrogels have been manufactured using 3D printing technologies, potentially paving the way for further 3D printing of pharmaceuticals. The 3D printing process enables simplified and automated manufacturing, accompanied by the fast turnaround that is necessary in early research and developments stages.

Aging populations and the need for new drug delivery formats, rapid testing and prototyping, and personalized medicines are all drivers for 3D printing in pharmaceuticals. However, overcoming the regulation and investment hurdles required for this approach to become mainstream may prove tricky, with uncertainty present throughout the value chain and a lack of coordination between companies in this sector.

Wider applications for 3D printing

IDTechEx’s report, “3D Printing and Additive Manufacturing 2024-2034: Technology and Market Outlook” covers the other major sectors for 3D printing extensively, including aviation, space, and defense. The report also describes in detail the most popular printing processes to date, including material extrusion, vat photo-polymerization, material jetting, and powder bed fusion, and the materials used in different applications.
