MODELING OF 3D PRINTING PROCESSES IN QUALITY MANAGEMENT OF THE CONSTRUCTION OF A PHYSICAL MODEL OF AN OBJECT

In recent years, the methods of layer-by-layer synthesis of prototype products, which is included in additive technologies, have formed a fundamentally new direction in technology, where it is necessary to produce experimental, single, exclusive and unique product samples. The fundamental difference between these methods is that the finished part is obtained not by removing a layer of material from the workpiece, as is customary in traditional methods of processing, and due to the layer-by-layer build-up of the material while obtaining a given shape and size of the product. At the same time, the main feature of these methods is the mandatory use of three-dimensional computer-aided design of the product as the initial stage of layer-by-layer synthesis technology. The use of these technologies is particularly promising in the production of housing elements of electronic equipment due to the ability to consider the specifics of the equipment. The use of additive technologies provides an increase in performance and a decrease in the influence of the form factor of the body at the production stage. An additional advantage of the additive installation is that in the manufacture of preforms are not required to resort to third-party technological solutions in the form of cutting, grinding, welding, which requires additional equipment and the involvement of qualified specialists. With the help of modeling mechanisms of 3D printers, it is possible to provide fully automatic production of preforms, having an additive installation. A process control additive production will ensure the quality of the final product.
