Practical application of basing theory for orientations of models of machine parts in their additive synthesis on 3D printers

On the basis of the formulated concepts of designbased additive synthesis, methodological, algorithmic and software for basing (orientation) of models of machine parts in the working area of a 3D printer is presented, the essence of which is the sequential determination and identification of possible compositions of surface orientation bases, determining the parameters of geometric accuracy of a 3D printer, the formation of a basic coordinate system (by superimposing geometric connections on the model) and its binding to the coordinate system of a 3D printer. With the help of the software, it is possible, as early as at the design stage, to predict the accuracy of the tolerances of the relative position of surfaces in 3D printing and to recommend options for basing models of parts in the working area of a 3D printer based on an analysis of its geometric accuracy to ensure these tolerances. These applications can be used by design departments of enterprises where 3D printers are used, by IT companies for creating and improving slicer programs, by educational institutions for training specialists in the field of manufacturing products based on three - dimensional technologies.
