Medical 3D Printing

medical 3d printing

Medicine has always been pioneering and cutting-edge. Starting in the 1990s, it began to move towards 3D printing, confirming its predisposition for innovation. This tool has begun to shape the medical landscape. Therefore, its combination of precision, customisation and speed has led to revolutionary developments in the field. It has changed the perspective of diagnosis, treatment and even research.

Dentistry and 3D printing

The first step was the use of 3D printing in the dental sector around the 2000s. The process involves a digital scan of the patient's mouth, which is then converted into a 3D model. This digital design allows dentists to design and print prostheses, crowns, bridges and other dental devices with unprecedented precision. In fact, the ability to create three-dimensional models of teeth and gums has transformed the planning of complex dental procedures. Dentists can now examine anatomical details with greater precision, anticipating challenges and reducing risks associated with surgical procedures. In addition, 3D printing has initiated the production of highly customised dental prostheses, ensuring a better fit and comfort for patients.

Orthopaedic prosthesis and 3D printing

3D printing has then found application in the sector of orthopaedic prostheses. With the ability to customise each part to the patient's anatomical needs, it has changed the lives of those in need of joint replacements or amputees. These prostheses, often made of medical ABS or other biocompatible polymers, offer better functionality, durability and comfort than traditional prostheses. Advantages include greater design freedom, faster production and better integration with the patient's body, adapting to their unique anatomy. The customisation provided by 3D printing also reduces the risk of post-operative complications and provides a better quality of life for patients.

Anatomical models and 3D printing

The creation of anatomical models through 3D printing has become a major advancement in the medical sector during the 21st century. Based on additive manufacturing, this technology has shown extraordinary potential. Customised anatomical models are obtained by means of medical imaging images, such as computed tomography or magnetic resonance imaging, which enable precise visualisation of individual anatomical conditions. This facilitates surgeons to plan complex operations and test different strategies before surgery, greatly reducing the risk of complications during operation.

These 1:1 scale anatomical models are also essential in medical education. This is because they offer medical students and surgeons in training a practical opportunity to better understand anatomical relationships and improve their diagnostic and surgical skills. Moreover, these anatomical models facilitate communication between doctors and patients by simplifying the illustration of complex medical conditions and possible treatment options.

The evolution of Bioprinting

Bioprinting is an emerging technology involving the printing of tissues and organs using biocompatible materials and living cells. It has made great progress since its inception, moving from simple cellular structures to complex three-dimensional tissue constructs. This technique has the potential to revolutionise regenerative medicine, offering solutions for the regeneration of damaged or diseased tissue. From engineering skin, cartilage and bone to creating synthetic organs such as the liver, heart and kidneys, it is redefining the concept of organ transplantation. Moreover, this technology enables the creation of tissue models for testing new drugs, reducing dependence on animal tests and accelerating the development of therapies.

One of the key features of bioprinting is the possibility of customising medical treatments. Through 3D scanning of the patient, tissue structures can be created specific to individual needs, reducing the risk of rejection and improving the effectiveness of treatments. This approach aligns with the growing emphasis on precision medicine, in which therapies are tailored to the unique genetic and physiological characteristics of each individual.
