Applications of 3D printing in healthcare

Abstract

3D printing creates a physical product from a digital file by layering various materials to form a single structure. Computer-aided design (CAD) files are necessary for the procedure. Due to its innovative and research-focused nature, 3D printing is well-suited to the medical industry. High-resolution anatomical images from MRI, X-ray, CT, or 3D ultrasound scans (3D scanning techniques) can create patient-specific models. Patients can receive inexpensive customized implants, prosthetics, and medical devices. 3D printing enables surgeons to operate more efficiently using personalized instruments and anatomical models. It also accelerates the development of new products for medical device manufacturers. In the pharmaceutical field, 3D printing allows for complex drug delivery systems, patient-specific implants, and tissue or organ creation. It facilitates telemedicine and tele-pharmacy by enabling the remote prescription and delivery of personalized medications. Additionally, personalized dosage forms simplify prescription regimens and enhance patient comfort. Besides this, key medical applications of 3D printing include tissue engineering, medical devices, drug delivery, and veterinary medicine.
