Research and development of rapid prototyping technologies allowedto move to a next level of optimization and the introduction of new processes in various areas of industry. At thestage of pilot production, which is characterized by frequent changes in design, the problem of the rapidproduction of cast components becomes crucial. This is mainly due to the complexity and the complexity ofmanufacturing foundry equipment. In turn, the research and development of rapid prototyping technologies haveallowed a new level of optimization and the introduction of new technologies in the investment casting. The aimof this work is to identify opportunities and evaluate accuracy of the size of the casting during investment castingusing rapid prototyping technology. The work was conducted with the use of cross-cutting design in CAM/CAD/CAE systems. The study size and precision parameters of the casting was conducted in coordinatemeasuring machine. The work has been verified the adequacy of the virtual simulation of the process of forminga casting in the casting simulation ProCAST, in comparison with those obtained castings. The study showed thatthe use of rapid prototyping technologies with investment casting can significantly reduce the time for makingcastings, reduce production costs and improve the accuracy of the size of the casting.</p>Additive technologyrapid prototypingsilicone moldwax modelceramic formАддитивные технологиибыстрое прототипированиесиликоновая формавосковая моделькерамическая форма[1.
