Application of additive electron-beam technologies
Innovative technologies of layer-by-layer production of products by the method of rapid prototyping open new opportunities for the production of parts of a given shape and structure with properties predicted in advance. The processes of manufacturing products by this method using an electron beam have shown great prospects for their application for the production of a wide range of parts and assemblies. This approach distinguishes the rapid transition to the production of three-dimensional products directly from the automated design system with the possibility of using a wide range of metals and alloys, including refractory and chemically active ones.
All currently existing industrial samples of similar equipment belong to foreign companies. There is no mass-produced domestic equipment. The technologies and equipment being created are focused on the needs of Ukrainian enterprises. For production, it is planned to use inexpensive domestic raw materials necessary for the manufacturer. This approach provides an opportunity to ensure the production of parts and assemblies based on the needs of the customer and in close contact with him. The technologies being developed will allow to reduce the terms of introduction into production of new types of products, to expand their assortment, as well as to manufacture fundamentally new types of products, the production of which is impossible without the use of 3D printing methods.
It is urgent to create equipment and software for it in Ukraine for the implementation of additive electron beam production, free from imported raw materials, oriented for implementation at enterprises of the aerospace industry and turbine construction: Motor Sich JSC, Pivdenne Design Office, Zorya-Mashproekt SE, LUTSK REPAIR PLANT MOTOR LLC.
In the conditions of martial law in Ukraine, it is urgent to provide the medical industry with reliable, competitive domestic implants and prostheses. Additive methods are the most effective for the production of individual medical products.
On the basis of industrial equipment for electron beam welding, experimental equipment for reproduction of additive processes has been created, and a hardware and software platform for controlling additive production has been developed. Prospective domestic metal powder materials suitable for additive manufacturing were studied. According to the additive technology, prototypes were manufactured and tested, and rational technological modes of surfacing were invented. Methods of designing products have been created. Printing of experimental samples for the needs of aircraft engine construction was carried out. Designed and manufactured individual medical implants.
