“…The results obtained in the second process gap (Figure 8d-f) give a more acceptable picture of the formation, with higher values of the SLM factors. The tracks were consistent and regular, which may be sufficient and satisfactory for the creation of solid metallurgical contact with the previous layers [83][84][85].…”

Problems with the laser additive manufacturing of metal parts related to its low efficiency are known to hamper its development and application. The method of selective laser melting of metallic powders can be improved by the installation of an additional laser beam modulator. This allows one to control the power density distribution optically in the laser beam, which can influence the character of heat and mass transfer in a molten pool during processing. The modulator contributes alternative modes of laser beam: Gaussian, flat top (top hat), and donut (bagel). The study of its influence includes a mathematical description and theoretical characterization of the modes, high-speed video monitoring and optical diagnostics, characterization of processing and the physical phenomena of selective laser melting, geometric characterization of single tracks, optical microscopy, and a discussion of the obtained dependences of the main selective laser melting (SLM) parameters and the field of its optimization. The single tracks were produced using the advanced technique of porosity lowering. The parameters of the obtained samples are presented in the form of 3D graphs. The further outlook and advanced applications are discussed.

“…Using supporting structure "Vortex" figurine part has been produced. "Vortex" part shape is combination of overhang, arc and having "negative" angle elements (Figure 3, a Results of determination of test specimen physical-mechanical properties, accuracy of linear dimensions and surface quality are given in Table 1 [6,7]. Table 1 shows that parts produced by SLM process from heat-resistant cobalt-based alloy have high physical-mechanical properties and this is typical for objects produced by surface laser melting [8,9].…”

“…Использование метода СЛП может сократить время изготовления и себестоимость деталей сложного профиля при единичном и мелкосерийном производстве за счет отсутствия стадии создания специального инструмента и сокращения количества технологических этапов, а универсальность лазерной обработки дает возможность синтезировать новые материалы и покрытия [6][7][8][9]. Изделия, изготовленные с помощью метода СЛП, являются перспективными в использовании, поскольку дают возможность управлять физико-химическими свойствами создаваемого изделия и получать изделия сложного профиля без применения дорогостоящих станков.…”

В работе исследованы фазовый состав и его изменения при температурных отжигах порошкового сплава Co66Cr28Mo6 и зубной коронки, полученной из того же порошка с помощью 3D- печати методом селективного лазерного плавления. Рентгенодифракционные исследования исходного порошка Co66Cr28Mo6 и неотожженной коронки показали, что лазерная печать полностью переводит двухфазный порошок (90 % ГЦК +10 % ГПУ) в однофазный твердый раствор ГЦК на основе высокотемпературной гранецентрированной кубической модификации b-Со с заметным увеличением межплоскостных расстояний по сравнению с b-Со. Работа выполнена при поддержке Минобрнауки России в рамках государственного задания ВУЗам в сфере научной деятельности на 2017-2019 годы. Проекты № 3.6263.2017/ВУ и № 16.8158.2017/8.9.
