The structure of the samples is eutectic: a solid solution based on aluminum is located inside intermetallic cells. A coarser eutectic structure with coarser cells is observed at the cell boundary. The microhardness of the samples was HV<sub>0,1</sub> = 115–170, the tensile strength was 370–475 MPa, and the ductility was 10–23%. Residual thermal stresses &lt;250 MPa were observed in the samples. An increase in energy density contributed to a decrease in strength characteristics, an increase in elongation, and a decrease in residual stress.</p></abstract><trans-abstract xml:lang="ru"><p>Селективным лазерным плавлением получены образцы сплава Al-Ce-Fe-Ni-Zr при скоростях сканирования 700–1900 мм/с. Структура образцов – эвтектическая (твердый раствор на основе алюминия находится внутри интерметаллидных ячеек). На границе ячеек наблюдается более грубая эвтектическая структура с ячейками большего размера. Микротвердость образцов составила HV<sub>0,1</sub> 115–170, предел прочности 370–475 МПа, пластичность 10–23%. В образцах наблюдаются остаточные термические напряжения &lt;250 МПа. Увеличение плотности энергии способствовало снижению прочностных характеристик, увеличению пластичности сплава, а также уменьшению остаточных макропапряжений.</p></trans-abstract><kwd-group xml:lang="en"><kwd>selective laser melting</kwd><kwd>additive manufacturing</kwd><kwd>aluminum alloys</kwd><kwd>mechanical properties</kwd><kwd>residual stress</kwd><kwd>microhardness</kwd><kwd>eutectic alloys</kwd><kwd>rare earth metals</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>селективное лазерное плавление</kwd><kwd>аддитивные технологии</kwd><kwd>алюминиевые сплавы</kwd><kwd>механические характеристики</kwd><kwd>макропапряжения</kwd><kwd>твердость</kwd><kwd>эвтектические сплавы</kwd><kwd>редкоэвиальные металлы</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Белов, Н.А.
