Design and Technological Solutions for Additive Manufacturing of Parts in the Volume of Material

Abstract

The features of technical solutions for additive manufacturing of parts are discussed. In contrast to existing solutions for layer-by-layer synthesis, a new method and device is proposed for the movement of a working tool in the volume of a powder. Various implementation options are considered using morphological analysis by constructing a morphological table. This ensures the validity of the proposed technical and technological solutions and, therefore, will improve the technical level and efficiency of the synthesized systems. An analysis has been made of solutions that provide less expensive production of three-dimensional objects due to better process control, which leads to higher productivity and reduced cost of both the technological process and the equipment. It also becomes possible to create more compact, lighter, and cheaper equipment for the synthesis of three-dimensional objects. The proposed technical solutions expand the functionality of the equipment by implementing both layer-by-layer (horizontal) synthesis and volumetric, vertical or mixed horizontal–vertical, synthesis of parts.
