После успешной апробации технологий моделирования методом наплавления (fused deposition modeling, FDM), стереолитографии (stereolithography, SLA), многоструйного моделирования (multi jet modeling, MJM) в части прототипирования и производства полимерных изделий общий вектор развития стремится к освоению технологий металлической печати заготовок и готовых деталей. Работы в этом направлении ведутся на ряде предприятий, и наибольшей популярностью в данном аспекте пользуются технологии селективного лазерного плавления (selective laser melting, SLM), дуговой сварки для сплавления металлической проволоки (wire arc additive manufacturing, WAAM) и высокоскоростного прямого лазерного выращивания (high-speed direct laser deposition, HSDLD). На текущий момент интерес ряда судостроительных компаний вызывает возможность производства заготовок деталей по чертежам отливок с применением технологии SLM. Однако стоит отметить, что в литературных источниках приводятся противоречивые данные о свойствах получаемых образцов, в частности в вопросах наличия анизотропии прочностных характеристик и соответствия геометрических отклонений имеющимся стандартам. Интересно в этом плане производство изделий сложной геометрии из нержавеющих сталей, что может быть использовано при изготовлении рычагов, вилок, корпусов спецоборудования, а также суперкавитирующих винтов и элементов консолей подводных крыльев для маломерных судов. В данной работе описываются физико-механические характеристики и геометрические отклонения образцов, полученных по технологии SLM на установке Laser Cusing M2 из нержавеющей стали 316L. Даются конкретные представления об анизотропии прочностных свойств и соответствии геометрии образцов требованиям к выпускаемой продукции. Представленные материалы могут служить отправной точкой для проведения прочностных расчетов изделий с учетом специфики аддитивных технологий и, в частности, SLM-процесса.</p></abstract><trans-abstract xml:lang="en"><p>Additive technologies are currently being actively implemented at the enterprises of the shipbuilding industry. After the successful testing of fused deposition modeling (FDM), stereolithography (SLA) and multi jet modeling (MJM) technologies in terms of prototyping and production of polymer products, the general vector of development seeks to master the technologies of metal printing of blanks and finished parts. Work in this direction is being carried out at a number of enterprises and the most popular technologies in this aspect are selective laser melting (SLM), wire arc additive manufacturing (WAAM) and high-speed direct laser deposition (HSDLD). At the moment, the interest of a number of shipbuilding companies is the possibility of producing blanks for parts according to castings drawings using the SLM technology. However, it should be noted that in the literature there are conflicting data on the properties of the samples obtained, in particular, regarding the presence of anisotropy of strength characteristics and the compliance of geometric deviations with existing standards. It is interesting in this regard to manufacture products of complex geometry from stainless steels, which can be used in the manufacture of levers, forks, housings of special equipment, as well as supercavitating screws and elements of hydrofoil consoles for small vessels. This paper describes the physicomechanical characteristics and geometric deviations of samples obtained by the SLM technology on a Laser Cusing M2 setup made of 316L stainless steel. Specific ideas are given about the anisotropy of strength properties and the compliance of the geometry of the samples with the requirements for the manufactured products. The presented materials can serve as a starting point for carrying out strength calculations of products, taking into account some specifics of additive technologies and, in particular, the SLM process.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аддитивные технологии</kwd><kwd>3D-печать</kwd><kwd>судостроение</kwd><kwd>316L</kwd><kwd>SLM</kwd><kwd>селективное лазерное плавление</kwd><kwd>прочность</kwd><kwd>физико-механические характеристики</kwd></kwd-group><kwd-group xml:lang="en"><kwd>additive technologies</kwd><kwd>3D printing</kwd><kwd>shipbuilding</kwd><kwd>316L</kwd><kwd>SLM</kwd><kwd>selective laser melting</kwd><kwd>strength</kwd><kwd>physical and mechanical characteristics</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Anisotropic response of Ti-6Al-4V alloy fabricated by 3D printing selective laser melting / L.
