ABSTRACT: Designing and creating implants used in medical practice, with regard to requirements and indications is a relevant and an important problem. The purpose is to create methodology for designing and subsequent growing implants with porous structure using the method of rapid prototyping on the example of jaw implants. The article discusses various technological methods for manufacturing implants, and the stereolithography method has been selected for obtaining it. The algorithm and the process of obtaining a 3D model of an implant based on the mathematical apparatus with the use of affine transformations have been proposed. On the basis of the developed software suite that uses mathematical relations, the configuration of the cellular structure has been chosen. Software implementation of the proposed algorithm has been performed, and the technological process of growing the cellular structure prototype by the stereolithography method at the Tec Invision Perfactory XEDE installation has been developed. Some calculation results have been shown along with a prototype of the jaw implant grown in accordance with the 3D models obtained from mathematical modeling. This technique makes it possible to switch to replacing or completely removing jaw defects (e.g., after trauma), if necessary, in maxillofacial surgery and in bone defects recovery.
