Abstract

Additive technologies (AT) are effective when processing relatively small batches of products, when high costs of materials is compensated by lowering fixed costs which are related to the use of traditional technologies. Aerospace equipment production is characterized, as a rule, within single and serial (small and medium series) types of production, which is why additive technologies will be in high demand in this field of engineering production. There is a necessary condition, regarding the widespread implementation and spreading of new technologies. It is its technical and economic efficiency. This article provides specific information on the comparative characteristics of classic and additive technologies of the common purpose and some pros and cons of these technologies. The main disadvantage of layer-by-layer synthesis of complexly shaped products is a relatively long duration of machine processing, resulting in high production costs, depreciation of equipment, and calculation of net costs. It is also noted that the feasibility study of AT use leads to reducing the number of workers and costs for maintaining on-site life safety. Also the usage of AT will lead to the reduction of shop and factory overhead costs due to cheaper logistics. In the field of aerospace engineering the major and promising direction of work in the field of additive manufacturing is to improve the technologies and equipment for the synthesis of products of ceramic and composite materials.
