The idea is to use alternative materials related to materials with functional classification and porosity in the human body. For example, the need for a replacement for human bones should be lightweight, rigid, non-toxic, and have an internal porosity that differs from the external surface. People now live longer and more comfortably when they experience fractures, amputations, and vertebral replacements, bone implants, which were previously unavailable or were limited and very expensive. These advancements highlight the ongoing efforts to enhance materials used in medical contexts, emphasizing functionality, biocompatibility, and the ability to interact harmoniously with the human body.

For example, the need for a replacement for human bones should be lightweight, rigid, non-toxic, and have an internal porosity that differs from the external surface. People now live longer and more comfortably when they experience fractures, amputations, and vertebral replacements, bone implants, which were previously unavailable or were limited and very expensive. These advancements highlight the ongoing efforts to enhance materials used in medical contexts, emphasizing functionality, biocompatibility, and the ability to interact harmoniously with the human body. The present study provides a review of materials with functional classification and porosity in medical applications and methods of their manufacture, which can be successful substitutes in the human skeletal system. Recently, regarding biocompatibility, PLA is considered excellent, making it suitable for medical and biomedical applications. The use of 3D printing technologies in manufacturing porous structures from various materials such as PLA, ABS, and Titanium shows that these manufactured structures have excellent mechanical properties and good biocompatibility. Based on the results, it is possible to design customized structures that meet specific needs by changing the size, shape, and porous structure ratio.
