Introduction to 3D printing in medicine
3D printing or additive manufacturing is a technology that is gaining popularity in various industries. It involves using a 3D printer to build a physical object layer-by-layer by using digital models created using computer-aided design software. The medical field has not been left behind in the adoption of 3D printing technology. In this article, we will explore the different ways 3D printing is currently being used in the medical field. But what is the first application of 3D printing in the medical field?
The very first application of 3D printing in the medical field was in 1999 when Dr. Scott Hollister, a pediatric surgeon at the University of Michigan, developed the first 3D printed tracheal splint. The recipient of the implant was an infant born with Tracheobronchomalacia, an extremely rare and potentially fatal disease that causes the airway to collapse. Traditional methods of treatment were not effective, and Dr. Hollister needed a custom solution for the infant’s airway. He collaborated with a medical-focused company called Materialise to create the 3D printed splint that could support and expand the infant’s trachea. The splint was designed based on CT scans of the child’s trachea and was made using a biocompatible polymer called polycaprolactone. The splint was designed to degrade gradually and be absorbed by the body as the child grew. The surgery was successful, and the infant survived. It was the first time in history that a 3D printed device was implanted in a human being. This was a groundbreaking achievement that led the way for other possibilities of 3D printing in medicine.
The development of the 3D printed tracheal splint opened the floodgates for more possibilities of 3D printing in medicine. The technology has been used in various ways to help improve medical outcomes for patients. It has been used to create prosthetics, surgical implants, and even organs. 3D printing technology allowed doctors to create patient-specific medical devices that fit the body perfectly, allowing for better surgical outcomes and faster recovery times. It has also significantly reduced the amount of time it takes to create medical devices, allowing patients to receive their customized implants much faster than traditional methods.
In conclusion, the first application of 3D printing in the medical field was the creation of the 3D printed tracheal splint, which was implanted in an infant with Tracheobronchomalacia. This marked the beginning of a new era in the medical field where 3D printing technology could be used to create customized medical devices for patients. Since then, the technology has been used in various other ways, and the possibilities are endless.

Custom prosthetics and orthotics creation
Medical applications of 3D printing technology have been revolutionary, providing new possibilities for patients where traditional medicine was often inadequate. By recreating the exact geometries of prosthetic and orthotic parts, 3D printing can significantly reduce the time required to produce them and allow patients to receive high-quality, personalized medical equipment. Here, we discuss how 3D printing is leading to custom prosthesis development and orthotics creation.
Prostheses are artificial devices used to replace a missing body part either due to injury, disease, or congenital disabilities. The production of prostheses is a process that requires extensive scanning, design, customization, and fitting to ensure the proper functioning and comfort of the device. In the past, it could take weeks or even months for a patient to receive their prosthesis due to the lengthy process.
Today, 3D printing has revolutionized this process, allowing the production of unique and highly customized prosthetic devices that fit perfectly to the wearer’s anatomy. Modern scanning techniques produce digital 3D models of the lost body part or area, and 3D printing technology can recreate them based on the digital model. 3D printing has made it possible to fabricate high-precision and custom-fitted prostheses at affordable prices, making them accessible to more people.
One such example of custom-fitted prostheses created with 3D printing technology is exoskeletons. The exoskeleton is a wearable prosthetic device that helps to restore the lower limb’s function to paralyzed or weakened users. These devices use a network of sensors, actuators, and electronics to control the limb’s movement of the user without the involvement of an external power source. 3D printing has enabled the manufacture of exoskeletons that are lighter, more affordable, and customizable to the user’s specific needs and comfort levels.
On the other hand, orthotics are medical devices used to support or align a part of the body, primarily the spine, arms, or legs. Orthotics, like prostheses, require precise measurement, accurate design, and customization to fit the wearer appropriately. Historically, orthotics used materials such as metal, foam, or plaster, which required time and skill to provide the best outcome. However, 3D printing technology has made orthotics creation significantly more accessible, faster, and more cost-effective.
Additionally, 3D printing allows for the creation of customized and highly precise orthotics. With the help of 3D printers, orthotic designs can be tailored to specific patient requirements for enhanced mechanical stability and personalization. One great use case of 3D printing technology in orthotics is the production of scoliosis braces. Scoliosis is a condition that causes the spine to bend sideways, affecting a person’s posture and overall well-being. Scoliosis braces are a non-surgical method of managing the condition that requires a highly accurate, customized device within the back of the patient’s torso. 3D printing has made it easier and quicker to produce customized scoliosis braces at an affordable price.
In conclusion, 3D printing technology is heralding a new era of prosthetic and orthotic production, offering a quicker, more personalized, and affordable solution. With the help of 3D printing, prosthetic and orthotic applications can produce devices that fit more precisely and offer better comfort and functioning. It is exciting to think about where 3D printing technology will take us to improve the quality of life for those in need.
