The article uses the technology of studying 3D-modeling and 3D-printing from several sets of programs, a brief description of several examples of the experimental use of 3D-printing. As a result, three-dimensional models of interior parts were carried out, the tasks of which were presented in the form of reduced-size samples printed on a 3D-model printer (Autodesk 3ds Max, Autodesk Maya, Graphisoft Rhino). Experimentally, as a result of converting to print formats, it turned out that some models have holes, which leads to a further technological cycle of preparing the model for printing. It included hole removal, printer setup, or model modeling in other ways. Experimentally it turned out that intersecting surfaces and primitives are not printed from Rhino.
