The role ofmethodsand materials in 3D-modeling

Abstract

The article deals with additive technologies of the XXI century and their use in industrial production. The technological process of creating objects on a 3D-printer is presented. The role of materials and their features for 3D-printing of various designs is revealed. The basic technologies of additive production are revealed, namely the work with various materials that open up perspectives in art, new opportunities for artists, sculptors, and designers to express their ideas in their original form. The features of 3D printing are determined by the technology of direct laser sintering (DMLS), selective laser melting (SLM) and selective laser sintering (SLS). The advantages of 3D printing of metal parts before the outdated methods are defined: mathematical modeling of the given characteristics, creation of forms previously unavailable for machine execution, etc. 3D printed metal parts require less energy, and the amount of waste is reduced to a minimum. It is noted that the introduction of three-dimensional printing - an important stage in the development of the aircraft industry, the use of various alloys in the detail significantly improves its physical and technical properties and gives the opportunity to bring the flight characteristics of the airplane to a fundamentally new level. Different materials used in the creation of sculptures, jewelry, as well as in the production of individual objects in the aerospace industry are presented. The prospects for affordable 3D-printing. 3D-printing is considered as one of the most promising technologies in the world, which in the foreseeable future can supplant modern prototyping techniques.
