So far, the level of development of 3D printing technologies and analysis of the market for 3D devices have been presented. The possibility of applying additive technologies as a tool in the educational process has been looked into. It has also been analyzed whether it is feasible to introduce the RP (Rapid Prototype) methodology. Issues associated with modernization of Prusa i3 3D-printer and options for its use in the educational process of institutions of higher education and schools have been studied. Conclusions have been made concerning possibilities of introducing 3D printing devices and RP methodology in order to reduce labor costs and design costs.
