Abstract (English):
Additive technologies or layer-by-layer synthesis technologies, 3D printing are the most dynamically developing direction of "digital" production today. The main advantages of additive technologies are: high precision, which allows taking into account the individual characteristics of a person and individual adjustment, improved properties of finished products. Due to the layer-by-layer construction, products have a unique set of properties. For example, parts created on a metal 3D printer in their mechanical behavior, density, residual stress and other properties are superior to analogs obtained by casting or mechanical processing. We can also highlight the significant savings in raw materials and labor. Additive technologies use almost the amount of material needed to produce your product. Whereas with traditional manufacturing methods, raw material losses can be up to 80-85%. Equipment for additive technologies allows you to produce items that cannot be obtained in any other way. For example, a part within a part. The use of superstructural plastics provides significant advantages in additive manufacturing compared to traditional metal materials. These polymeric materials have high strength, rigidity, wear and corrosion resistance, as well as excellent molding and processing capabilities. Due to these properties, they can be used to create lightweight, strong and durable medical products such as implants, prostheses and instruments. In the process of work, scientific articles devoted to the use of superstructural plastics in additive manufacturing were analyzed. It was revealed that the most common plastic for 3D printing is polyetheretherketone, which is characterized by heat resistance, good strength characteristics and biocompatibility, which allows it to be used in many areas of medicine: as maxillofacial, hip, dental implants, discs and dental prostheses, the possibility of its use in the development of medical instruments for doctors and anatomical models for training medical personnel in complex operations and manipulations is being studied. Polyphenylene sulfone and polysulfone are only being studied for use in additive technologies for medicine in the future, while this direction is more of a research nature than applied. Gradually, these types of superstructural plastics are being introduced and will be used in medicine. The use and expansion of the range of application of types of superstructural plastics, as well as their development for use in 3D printing for medicine contributes to import substitution.
