Abstract
The results of experimental studies to determine the possibility of obtaining carbonized material based on lime-carbonate-calcium compositions using inkjet 3D printing are presented. Some types of materials used as connecting for inorganic binders have been studied. An effective method of hardening the model obtained in the process of 3D printing is determined. The physicomechanical characteristics of prototypes solidified in an environment of high concentration of carbon dioxide are defined. It has been established that artificial carbonization of samples obtained on various types of binders for 90 minutes contributes to the formation of a sufficiently strong structure from insoluble calcium carbonate, a product of carbonation of hydrated lime. In this case, the degree of carbonization depends on the type of binder and its mass fraction in solution. The most effective types of binders are selected and the optimal content of the binders in solution is determined. In result, to ensure the production of materials with sufficient physicomechanical properties, a possibility of obtaining carbonized material by the method of 3D inkjet printing at certain optimal contents of the tested binders is confirmed.

Summary
Данные лазерного анализа размера частиц позволяют сделать вывод о пригодности порошка пушенки кальциевой для использования в струйной 3D печати. Результаты определения клеящей способности растворов связующих показали, что раствор сахарной пудры наиболее эффективен с точки зрения получения твердого слоя распределенного порошка уже после пяти минут распыления связующего. 2 можно сделать выбонизации образцы высушивали до постоянной вод, что процесс активной карбонизации прохомассы, после чего определяли их свойства – дит для всех видов связующих, о чем свидетельпрочность на сжатие, Rсж, среднюю плотность, ствует увеличение средней плотности, прочноρо, и водостойкость, Kp. Испытания на проч- сти при сжатии карбонизированных образцов ность на сжатиеопытных образцов проводили на от до 32 раз в сравнении с образцами без каравтоматической системе испытаний на базе кон- бонизации. Физико-механические свойства опытных образцов на различных связующих до и после карбонизации
