This is usually achieved by adding special fillers to the polymer matrix and, as a result, obtaining a composite polymer with new, significantly different properties. A separate type of composites – conductive polymer materials – is an important functionality for 3D printing products that have many potential applications, The purpose of the work is to improve the method of creating polymer composites and filaments based on them, to establish the laws of deposition of composite filament during the additive formation of embedded elements for welding, to study the properties of composite embedded elements and welded joints formed with their use. The work uses a modern consumable biopolymer material - polylactide (PLA), ecological, biocompatible, with high strength indicators. However, the available number of studies does not provide a complete picture of the nature of the processes in this material during FDM 3D printing. The method of forming electrically conductive composites based on PLA and carbon filler and obtaining filaments for 3D printing from them was improved. Computer modeling of the segregated structure of micro-composites based on polylactide filled with technical carbon showed the presence of a continuous framework of carbon microparticles in the material, which determines its electrical conductivity. Electrically conductive polymer composites were created by the method of hot compaction and electrically conductive filaments were formed on their basis, and polymer base heating elements were made by the method of FDM 3D printing. The dependence of the electrical conductivity of composite filaments and embedded elements from them on the concentration of carbon microfiller was studied. It is shown that the values of electrical conductivity and mechanical strength of products made of composite m Product Description popup.authors Demchenko Valerii L.
