This paper describes an experiment that made it possible to obtain helical multiwalled carbon nanotubes (НMWCNTs) with a diameter of 30–60 nm by pyrolysis of hydrocarbons and trapping the product with a liquid seal. For the purpose of comparative analysis, the paper also considers the synthesis of straight multiwalled carbon nanotubes (SMWCNTs). Such carbon nanotubes after preparation can be used in CJP 3D printing technology. All obtained materials are examined using the method of transmission electron microscopy. The paper considers the processes of synthesis of HMWCNTs and SMWCNTs. An assessment of the strength characteristics of 3D products from various composites based on them after discrete 3D printing and sinter-ing is carried out. The conditions for the synthesis of carbon nanostructures by the pyrolytic method are described, methods for preparing synthesis products for their subsequent using in 3D printers of CJP, FDM, SLA, SLS technologies are developed, and the technology for preparing mechanical mixtures for 3D printers of CJP technology is developed. In addition, a technique for creating 3D products from composite materials is considered. The bending strength of 3D printed ceramics reinforced with carbon nanotubes is measured. The dependence of the bending strength of the obtained ceramics on the amount of MWCNTs in the composite is established. The resistance to mechanical destruction of composites (MWCNTs–Al2O3) obtained using helical and straight MWCNTs is studied. At the same time, it is shown that when using SMWNT, after the integrity of the composite is broken, the parts of the product do not crumble, but remain united even under load.
