3D Printing Technology in Medicine and Healthcare

Additive manufacturing, or 3D printing, originated in the 1980s, and since its invention has achieved a wide range of applications across a variety of industries, with particular potential in the healthcare sector. Within the healthcare sector, the technology has been successfully applied to the development of replacement organs, prosthetics, medical devices, and much more.

In this article, we will explore the significant advantages of additive manufacturing in the medical field, and the FDA regulation that ensures that additively manufactured products meet stringent quality and safety standards, and finally, additive manufacturing and its prospects for growth.

What is medicine and healthcare?

“Medicine and health care” refers to procedures and practices related to the prevention, diagnosis, treatment, cure and mitigation of disease.
The concept also includes the study of physical and mental health investigations.

Practice of medicine:

Activities involved in the prevention, diagnosis and treatment of disease and injury.
The scope is broad and includes a wide range of medical practices such as prescribing medications and surgery.


Includes not only activities and services that maintain and improve people’s health.
It also covers the entire support structure for professionals who provide care, such as pharmacists and therapists, and engineers who design and manufacture healthcare products.

How can 3D printing technology help healthcare?

Customized Medical Devices and Equipment: 3D printing can be used to create customized medical devices and equipment such as prosthetics, orthotics, dental braces, etc. These devices can be customized to a patient’s specific anatomy and needs, improving treatment outcomes and patient comfort.

Bioprinting: 3D printing technology is also used for bioprinting, which is the printing of human tissues and organs. This technology is expected to be used in experimental studies prior to organ transplantation to provide better treatment options for patients. Currently, a number of small tissues have been successfully printed in a laboratory setting, although the challenge of bioprinting entire organs remains.

Surgical Models: 3D printing can create accurate anatomical models that help doctors simulate actual operations before surgery. This helps to improve the accuracy and reduce the risk of surgery.

Drug customization: 3D printing technology can be used to create personalized medications, tailoring the dosage and shape of the drug to the specific needs and physiological characteristics of the patient, improving the effectiveness of the treatment.

Medical Devices and Components: 3D printing can be used to produce medical devices and components, such as patient-specific surgical tools, surgical aids, support and immobilization devices, and more. This customized production can be better adapted to the patient’s needs.

DENTAL APPLICATIONS: 3D printing has a wide range of applications in the field of dentistry, including the production of crowns, bridges, dentures, and more. This not only improves productivity but also provides better personalized solutions.

Medical Education: 3D printing technology provides high-quality anatomical models for use in medical education, helping medical students better understand human structures and organs.

How does the FDA regulate 3D printers and printed products for medical use?

FDA Regulatory Scope: The FDA is responsible for regulating 3D printers and products for medical use, but not directly regulating the printers themselves.

Focus of Concern: The FDA focuses on the medical devices manufactured through these printers and their manufacturing processes to ensure that the products are safe, effective, and of high quality when placed on the market.

Regulatory Approach: The FDA uses a similar regulatory approach to other medical devices, categorizing products into low, medium, and high risk categories and reviewing them accordingly.

Lack of Specific Guidance: Although the FDA has not issued guidance specific to 3D printing in the pharmaceutical or biological fields, these products are still regulated under other existing FDA oversight pathways.

Regulatory Limitations: Outside of FDA regulations, regulation of medical 3D printing is more limited, with state-level medical boards potentially able to oversee specific providers when they pose a risk.

Product Types: As of today, the majority of FDA-reviewed products created through 3D printing are primarily medical devices such as orthopedic implants.

What are the Disadvantages of 3D Printing in Medicine and Healthcare?

While 3D printing has many advantages in the medicine and healthcare industry, there are some potential drawbacks, including:
Investment costs: investing in 3D printers can be expensive and material costs can be high, which can be a barrier for some healthcare providers and patients. However, the cost savings in terms of reduced material waste, energy savings, and time efficiencies do justify its use by some manufacturers.
Limited Materials: While 3D printing can produce a wide range of materials, there are limitations on the types of materials that can be used for medical applications.
Quality control: Ensuring the quality and consistency of 3D printed medical products can be challenging, especially when producing complex structures or patient-specific devices. This can raise concerns about the safety and efficacy of these products.
Regulatory challenges: The regulatory framework for 3D printing in medicine and healthcare is still evolving. Ensuring compliance with regulatory standards can also be time-consuming and expensive.
Lack of standardization: There is a lack of standardization in terms of software, hardware and materials. This makes it difficult to compare products and ensure consistency in manufacturing and quality control.

The safety of 3D printing technology in the medical and healthcare fields depends on a number of key factors, including the materials used, the design of the product and the manufacturing process. Overall, 3D printing technology is safe when used correctly and in accordance with established guidelines and standards.

To address these issues, regulatory agencies such as the FDA have developed a series of guidelines and standards for the design, production and testing of 3D printed medical devices. Healthcare providers and manufacturers must follow these guidelines to ensure the safety and effectiveness of their products in the marketplace. They are designed to regulate the use of 3D printing technology to minimize potential risks and ensure the safety of patients and healthcare professionals.

Are the materials used in 3D printers safe for medical use?

No, not all materials used in 3D printers are safe for medical use. However, there are many materials that are approved for medical applications. For example, biocompatible materials such as medical-grade titanium and cobalt chromium alloys are used to produce implants and other medical devices. There are also biocompatible polymers such as polyethylene terephthalate (PETG) and polylactic acid (PLA) that are commonly used in the production of medical devices, prosthetics and orthotics.

It is important to note that the safety of materials used in 3D printing depends on several factors beyond the chemical composition, such as the intended use of the product, the type of printer, the printing process, and the quality of the material. Materials that have not been properly tested or approved for medical use may cause harm to patients.
