These models can also be easily adapted to solve specific problems of patients and doctors. 3D printers are currently used to build not only custom prostheses for needy patients, but also a wide variety of other medical elements, mainly tissues and organoids, as well as surgical models and tools. An estimated 13 percent of 3D printing revenues come from the medical field and by 2025 approximately $ 3.19 billion in technology will be spent in that sector. That’s more than $ 2 billion more than in 2018 ($ 1.13 billion), a composite annual growth rate of 15.89 percent.
The most commonly used technology for 3D printing of medical devices is called dustbed fusion. Powder bed fusion is often used because it works with a variety of materials used in medical devices, such as titanium and nylon. After that, the ultimate goal is to create freight dimensioning systems blood vessels ready to be implanted in patients. Because tissue engineering uses cells that the patient’s patient needs treatment, it eliminates the possibility of immune system rejection, a major problem in today’s conventional organ transplant procedures.
This gives them a practical opportunity to develop the most accurate and least invasive approach to surgery. To create these models, physicians use specialized equipment that converts images from a patient’s two-dimensional computed tomography or magnetic resonance imaging into a 3D model, which is then printed with a material such as acrylic. Sometimes plastic surgeons have to move a nose or create a stronger jaw, either for cosmetic purposes or to improve function.
Today, 3D printing technology offers a great opportunity to help pharmaceutical and medical companies create more specific drugs, enabling rapid production of medical implants and changing the way doctors and surgeons plan procedures. Patient-specific 3D-printed anatomical models are becoming increasingly useful tools in current precision science practice and for personalized treatments. Implantable 3D-printed organs are likely to be available in the future, reducing waiting lists and increasing the number of lives saved. The purpose of this analysis is to demonstrate through in-depth research of 3D printing applications in the medical field the usefulness and disadvantages and the powerful technology it is.
Helps the surgeon in spatial orientation in the cavities of a small heart and simulate the surgical approach and steps of the surgery with great fidelity . This leads to a shorter intraoperative time than in itself, with a significant impact on the number of complications, blood loss, duration of postoperative stay and lower costs . Assessment of optimal stent position, size and length proved useful for actual patient intervention. This is one of the most technically challenging surgical procedures that opens the door to possible simulation applications of a 3D model in the field of catheterization and cardiovascular interventions . By changing the ultimate goal of additive manufacturing, other cases of applications in the literature are reported to demonstrate the usefulness of producing patient-specific pediatric prostheses. An example in literature is the development of a cheap three-dimensional printed prosthetic hand for children with a reduction of the upper limbs using a methodology for remote adjustment .
3D printers are getting closer to being able to produce organs and progress is also being made on other fronts. Complexity: Surgical implants require the host tissue to accept complex and organic structures. These constructions are priceless with traditional production methods, but a 3D printer can make them at no extra cost. There are several reasons why additive manufacturing works perfectly for medical applications.
