На начальном этапе внедрения новых способов производства в различные отрасли промышленности, как правило, применяют наиболее изученные и широко используемые на практике методы контроля. В большинстве случаев это стандартные разрушающие испытания. В качестве альтернативы стандартным испытаниям на растяжение, применяемым для оценки упругих и прочностных свойств полимерных изделий, полученных по SLA-технологии, в работе предложен метод динамического индентирования. На примере высокотемпературной фотополимерной смолы High Temp RS-F2-HTAM-01 показана возможность оптимизации способов 3D-печати и режимов постобработки на основании данных динамического индентирования. Показано, что наибольшему охрупчиванию подвержены непигментированные фотополимеры из-за своей возможности пропускать УФ-излучение в объём синтезированного материала. Выявлено, что охрупчивание полимерного материала в меньшей мере сказывается на результате измерения его динамической твёрдости, чем предела прочности при растяжении. Установлено, что доотверждение полимерных изделий при высоких температурах (вплоть до 160 °С) и УФ-излучении мощностью 39 Вт позволяет повысить их прочность и модуль упругости на 170 % и 85 % соответственно, по сравнению с состоянием до обработки. Доказано, что чувствительность метода динамического индентирования к изменению физико-механических характеристик изделий, полученных по SLA-технологии при различных видах и режимах их постобработки, сопоставима с чувствительностью стандартных испытаний на растяжение.</p></abstract><trans-abstract xml:lang="en"><p>Innovative production technologies, such as additive synthesis, is inextricably linked with the development of methods for assessing the quality of manufactured products. At the initial stage of introducing of new production methods into various industries, the most studied and widely used control methods are usually used. In most cases these are standard destructive tests. As an alternative to standard tensile tests used to evaluate the elastic and strength properties of polymer products produced using SLA-technology, the dynamic indentation method is studed in this work. Using the samples of the high-temperature photopolymer resin High Temp RS-F2-HTAM-01, the possibility of optimizing 3D printing methods and post-processing modes based on dynamic indentation data is shown. It has been shown that non-pigmented photopolymers are most susceptible to embrittlement due to their ability to transmit UV radiation into the volume of the synthesized material. It was found that the embrittlement of a polymer material has a lesser effect on the result of measuring its dynamic hardness than on its tensile strength. It has been established that post-curing of polymer products at high temperatures (up to 160 °C) and UV radiation with a power of 39 W can increase their strength and elastic modulus by 170 % and 85 %, respectively, compared to the state before treatment. It has been proven that the sensitivity of the dynamic indentation method to changes in the physical and mechanical characteristics of products obtained using SLA-technology under various types and modes of their post-processing is comparable to the sensitivity of standard tensile tests.</p><p> </p></trans-abstract><kwd-group xml:lang="ru"><kwd>неразрушающий контроль</kwd><kwd>аддитивные технологии</kwd><kwd>полимерные материалы</kwd><kwd>физико-механические характеристики</kwd><kwd>метод динамического индентирования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>non-destructive testing</kwd><kwd>additive technologies</kwd><kwd>polymer materials</kwd><kwd>physical and mechanical characteristics</kwd><kwd>dynamic indentation method</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Белорусского республиканского фонда фундаментальных исследований: проект № Т22М-004 «Развитие метода локального контактного деформирования для неразрушающего контроля полимерных изделий, полученных путём аддитивного синтеза».</funding-statement><funding-statement xml:lang="en">The work was carried out with the support of the Belarusian Republican Foundation for Basic Research: project No. T22M-004 "Development of a local contact deformation method for non-destructive testing of polymer products obtained by additive synthesis".</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Godec Damir, Gonzalez-Gutierrez Joamin, Nordin, Axel, Pei Eujin, Ureña Alcázar Julia.
