This particular case shows that advances in computer-aided design programs, additive manufacturing and image editing software provide the ability to design, print and install prosthetic handheld devices that overcome cost constraints. As a result, the benefits of 3D-printed implants over conventional implants in terms of customization and cost are, as seems clear in the previous example. In contrast, the biggest setback is related to the rapid physical growth that often causes personalized prostheses to be overcome. This leads to the production of advanced technological implants that increase costs due to their high complexity and weight. Additive production can be used to create sturdy, lightweight, easily replaceable and very cheap prostheses for children . The lack of main prostheses is related to the ability to communicate with the brain in terms of sensitivity.
With the advent of bio-impression, cellular prostheses can be an interesting research area, which can lead to prostheses that are integrated in the brain communication system and may exhibit more biomimetics with tissue and organ functionalities . Used for personalized preoperative treatment / treatment and for preoperative planning. This will lead to a multi-step procedure that, by integrating clinical and imaging information, will determine the best therapeutic option. Several studies have shown that patient-specific preoperative planning can reduce operating room time and lead to fewer complications . In addition, this can lead to a reduction in post-operative residence, a reduction in the intervention rates and lower health care costs.
There are many successful cases that demonstrate the potential of additive production in surgical planning in pediatric cases. In particular, most 3D printing applications reported in the literature relate to congenital heart disease . This is because children have a smaller chest cavity than adults, and surgical treatment in pediatric cases can be much more difficult. Additive production helps surgeons to have more information than the only ones who can afford imaging technologies.
This allows doctors and nurses to study a topic from multiple angles and hopefully find a solution to the medical problem. Additive production is an affordable way to produce anatomical models; Both medical students and experienced professionals benefit from this technology. Thanks to a process called bioprinting, medical 3D printers can now print freight dimensioning systems functional tissue. Soon, 3D printers in the medical field will be able to make tissue to help with skin grafting and reconstructive surgery. Labs are also starting to experiment with liver and intestinal tissue printing to control certain diseases. 3D printing in the field and medical design should think outside the norm to change medical care.
With regard to medical applications, similar to other applications, different anatomical structures require different mechanical properties of the materials to meet the required performance of the printed object . The main distinction between the different materials that characterize the human body is between stiff and soft materials. Human bones are an example of stiff tissue and ligaments or articular cartilage are examples of soft materials. Bones are the simplest and easiest organic fabric to produce by 3D printing, as most materials are rigid. The materials used in 3D printing to model the bone structure are, for example, acrylonitrile-butadiene-styrene, gypsum powder and hydroquinone .
Although this technique is reminiscent of 2D printing methods, it actually comes closer to Binder Jetting technology. In the case of drug production, combinations of active ingredients and excipients or inks are sprayed through the mouthpiece, creating the structures layer by layer. In the same year that Spritam arrived, Dr. Martin Burke of the Howard Hughes Medical Institute and his team of researchers developed a 3D printer to make medicine through molecules. This was achieved by noting that in the case of small molecules there are some repetitive patterns. Therefore, they isolated hundreds of these patterns and created a 3D printer that they could assemble to create the desired molecule, enabling custom pills to be developed.
