Research of new materials and approaches in additive technologies in the manufacture of prototypes in industrial design

Abstract

In industrial design, in the manufacture of the prototype, the task of choosing the technology and material for its manufacture is taken. At the minimum cost of material, it is necessary to obtain a prototype with high strength indicators, which will guarantee the implementation of the tasks for which the prototype was conceived. The use of additive technologies allows you to get prototypes with a cellular internal structure, which can significantly save the expendable material when prototyping the future product. In this paper, we analyze the approaches that contribute to improving the strength characteristics of a prototype made using additive technology, and also show the promise of research in the direction of finding the shape of cells with the greatest strength. As a hypothesis, it has been suggested that an increase in the strength characteristics of the prototype can be achieved by introducing nanostructured materials into the polymer. Studies were conducted on the synthesis of nanostructured materials in low-temperature plasma and their modification of polylactide. Samples were made from modified polylactide and their strength characteristics were investigated. An analysis of the results showed an increase in the strength characteristics of samples of modified polylactidapo compared with samples made of primary polylactide without nanostructured components.
