Additive Manufacturing technologies in the medical sector
Introduction:
Additive Manufacturing (AM) technologies, also known as 3D printing, have revolutionised the manufacturing industry with its ability to create complex and customised objects quickly and efficiently. The use of AM technologies in the medical sector began in the late 1980s and early 1990s when medical professionals started using 3D printing to create models for surgical planning and education.
By the early 2000s, they were being used to create prosthetic limbs, orthotics, and dental implants. As the technology became more accessible, it advanced to create patient-specific implants, surgical guides, and other devices. Advancements in bioprinting and functional organs have been developed, leading to increased use in the medical sector. Future growth is expected in the field of AM technologies in the medical sector with more applications and advancements.
Materials used in AM technology in the medical sector:
Polymers: These materials are commonly used for 3D printing of medical devices such as prosthetics, surgical instruments, and drug delivery systems.
Metals: Metals such as titanium, cobalt-chromium, and stainless steel are commonly used in the production of implants such as hip and knee replacements.
Ceramics: Ceramic materials such as zirconia and alumina are used for 3D printing of dental implants, bone substitutes, and other medical devices.
Biologics: This includes living cells, proteins, and other biological materials that can be used in bioprinting to create tissue and organ structures.
Some Medical sectors where Additive Manufacturing (AM) is used:
Orthopedics:
AM technology creates customised implants, surgical guides, and prosthetic limbs in orthopedics. This leads to better patient outcomes, lower costs, and reduced surgery time. The technology also improved prosthetic function by creating more durable and customised devices.
Dental:
AM technology is used in dental to create patient-specific dental implants, crowns, and bridges. This is done by using a patient's CT or MRI scans to create precise models of their anatomy. The use of AM technology in dental results in improved patient outcomes, reduced surgery time, and lower costs.
Cardiovascular:
AM technology is used in cardiovascular medicine to create patient-specific models of the heart for surgical planning, and to create customised stents. 3D printed heart valves are also being developed for potential future use.
Bioprinting:
Bioprinting uses AM technology to create 3D biological structures, including skin, bone, and cartilage, using living cells. It has potential applications in tissue engineering, drug discovery, and personalised medicine, and has the potential to revolutionise healthcare by creating patient-specific tissues and organs.
Challenges and limitations:
Cost of Equipment
Availability of Materials
Regulatory Approval
Limitations in Design
Surface Finish
Need a skilled Professionals
Few live examples of people whose lives have been positively impacted by AM technology in the medical sector:
Six-year-old Alex Pring was born without his right arm and had always struggled in life, but students from the University of Central Florida (UCF) have created a 3D printed prosthetic arm so he can fulfil his dream of shaking hands and climbing trees.
Anelia Myburgh can attest to this as she was recently the recipient of a 3D printed jaw implant. And while so many implants today are responsible for improving the quality of life of patients, Myburgh was particularly grateful to have a chance for facial reconstruction.
Conclusion:
AM technologies have enabled the creation of customised medical devices and new technologies such as bioprinting. However, challenges such as the cost of equipment and availability of materials still exist. Despite these challenges, the use of AM in the medical sector is expected to grow, leading to improved patient outcomes and reduced healthcare costs.
