Предлагаемая конструкция включает самодельный механизм подачи и разравнивания порошка, а также телеметрический модуль, обеспечивающий сбор и анализ термических данных в реальном времени. Цифровой двойник представляет собой интегрированную модель, совмещающую термомеханический анализ, исполнение управляющего кода (G-code) и реализацию корректирующих воздействий на параметры печати. В качестве расчетной основы использовано уравнение нестационарной теплопроводности с объемным источником тепла и гауссовым распределением плотности мощности лазерного луча.Для верификации модели проведён эксперимент с использованием пирометров и термопар, размещённых в зоне спекания. Сравнение результатов моделирования и измерений показало среднюю абсолютную ошибку менее 2,5 °C. Применение цифрового двойника обеспечило снижение остаточных напряжений на 12-15 %, что подтверждено методом рентгеновской дифракции. Разработанная система демонстрирует высокую эффективность в обеспечении предиктивного контроля качества и может быть интегрирована в контур адаптивного управления. Решение соответствует концепции Индустрии 4.0 и открывает возможности для повышения стабильности, воспроизводимости и надёжности SLM-процессов.</p></abstract><trans-abstract xml:lang="en"><p>This paper presents the development and experimental validation of a digital twin for a selective laser melting (SLM) system designed for operation under constrained technical conditions. The proposed design includes a custom-built powder feeding and leveling mechanism, along with a telemetry module enabling realtime acquisition and analysis of thermal data. The digital twin is implemented as an integrated model that combines thermomechanical analysis, G-code execution, and corrective control of printing parameters. The mathematical foundation is based on the transient heat conduction equation with a volumetric heat source and a Gaussian distribution of laser power density.An experimental setup employing pyrometers and thermocouples in the melt zone was used to validate the model. The comparison of simulated and measured data showed a mean absolute error of less than 2.5 °C. The application of the digital twin resulted in a 12–15% reduction in residual stresses, as confirmed by X-ray diffraction analysis. The developed system demonstrates high efficiency in predictive quality control and can be integrated into adaptive control loops. The approach aligns with the Industry 4.0 concept, offering increased stability, repeatability, and reliability in SLM processes</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Цифровой двойник</kwd><kwd>SLM</kwd><kwd>3D-печать</kwd><kwd>термомоделирование</kwd><kwd>аддитивное производство</kwd><kwd>предиктивная аналитика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Digital twin</kwd><kwd>SLM</kwd><kwd>3D printing</kwd><kwd>thermal modeling</kwd><kwd>additive manufacturing</kwd><kwd>predictive analytics</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Статья опубликована в рамках выполнения научного проекта грантового финансирования на 2024-2026 годы ИРН AP23490424 «Разработка аддитивной установки для создания металлических объектов для оборонной промышленности» (исследование финансируется Комитетом науки Министерства науки и высшего образования Республики Казахстан).</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">Тулегулов А.Д.
