However, to improve the 3D printing productivity, it is impossible to increase simply the speed of the squeegee without changing its shape or type. In this case, the quality of the powder layer may suffer, which will lead to a deterioration in the qualities of the final part. To study the effect of roller characteristics on the powder layer deposition, a series of computer simulations of simulation models was carried out. The effect of roller characteristics on the powder layer applying, was assessed, for roller diameters of 30, 50, 70, 100, 150, 200, 250, 300 mm. The simulation was carried out with three application methods: by a rotating and non-rotating roller, as well as by a rotating roller with additional powder feed. It was determined that when applying a layer with a rotating roller with additional powder feed, it is possible to achieve constancy of the forces acting on the roller. This can positively affect the homogeneity of the applied layer. The application of a layer by a rotating roller with additional powder feed is most suitable for 3D printers with a large print area. This method allows avoiding the movement of a large mass of powder over the previous layer, which positively influences the quality of the final part. The study revealed the influence of roller characteristics on the deposition of a powder layer. In particular, with an increase in the roller diameter from 30 to 300 mm, the peak force value also increases. With an increase in the roller diameter by 7.9 %, the powder layer density also increases. It was found that the non-rotating roller is affected by the greatest force, and the forces acting on the rotating rollers differ slightly. A rotating roller, without adding powder, creates the densest layer and allows achieving a powder layer compaction of 5.35 %.</p></abstract><trans-abstract xml:lang="ru"><p>При исследовании и анализе аддитивных технологий особое внимание уделяется повышению производительности и качества напечатанных изделий. Однако для повышения производительности 3D-печати нельзя просто увеличить скорость перемещения ракеля без изменения его формы или типа. Из-за этого может пострадать качество порошкового слоя, что приведет к ухудшению качеств конечной детали. Для исследования влияния характеристик ролика на нанесение порошкового слоя проведена серия компьютерных моделирований имитационных моделей. Оценка влияния характеристик ролика на нанесение порошкового слоя проводилась для диаметров ролика 30, 50, 70, 100, 150, 200, 250, 300 мм. Моделирование проводилось с тремя способами нанесения: вращающимся и невращающимся роликом, а также вращающимся роликом с подачей дополнительного порошка. Определено, что при нанесении слоя вращающимся роликом с дополнительной подачей порошка можно достичь постоянства сил, действующих на ролик. Это может положительно повлиять на однородность наносимого слоя. Нанесение слоя вращающимся роликом с дополнительной подачей порошка наиболее пригодно в 3D-принтерах с большой зоной построения. Данный способ позволяет избегать перемещения большой массы порошка по предыдущему слою, что положительно влияет на качество конечной детали. Выявлено влияние характеристик ролика на нанесение порошкового слоя. В частности, при увеличении диаметра ролика с 30 до 300 мм увеличивается и значение пиковой силы. При увеличении диаметра ролика на 7,9 % увеличивается и плотность порошкового слоя. Выявлено, что на невращающийся ролик действует наибольшая сила, а силы, действующие на вращающиеся ролики, незначительно отличаются. Вращающийся ролик без добавления порошка создает наиболее плотный слой и позволяет добиться уплотнения порошкового слоя на 5,35 %.</p></trans-abstract><kwd-group xml:lang="en"><kwd>roller characteristics</kwd><kwd>powder layer</kwd><kwd>additive technologies</kwd><kwd>additive manufacturing</kwd><kwd>roller diameter</kwd><kwd>powder layer levelling</kwd><kwd>powder layer applying</kwd><kwd>powder layer density</kwd><kwd>squeegee</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>характеристики ролика</kwd><kwd>порошковый слой</kwd><kwd>аддитивные технологии</kwd><kwd>аддитивное производство</kwd><kwd>диаметр ролика</kwd><kwd>разравнивание порошкового слоя</kwd><kwd>нанесение порошкового слоя</kwd><kwd>плотность порошкового слоя</kwd><kwd>ракель</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Chen Hui, Chen Yuxiang, Liu Ying, Wei Qingsong, Shi Yusheng, Yan Wentao.
