This paper deals with the areas of 3D modeling and 3D printing, also the development of 3D models of modular archery equipment which shows a concrete example of the application of 3D modeling in the field of 3D printing. 3D modeling is described from the very beginning of history to modern times, the two types of programs used for 3D modeling are described, of which the programs of each type that was used were also described. The development of 3D printing technology is also described, as well as the existing 3D printing techniques, of which the FDM 3D printing technique is described in detail. Different types of FDM 3D printers are described depending on the printing system and build type, as well as the most important parts of FDM printers and most commonly used materials in FDM printing. The process of preparation of 3D models for printing is described, as well as the programs used in that process, of which a concrete example of the program used is described. The whole process of creating the project task was described, which was the design and printing of 3D models of modular archery equipment which show the application of 3D modeling in the field of 3D printing as an example of rapid prototyping of new products.
