The additive technology of direct laser deposition (DLD) belongs to the class of 3D printing methods for metal parts and constructions. It is promising for the manufacture of large-sized complex parts for the aviation and shipbuilding industries. Methods of additive production dictate serious requirements for the properties of building powders, but with the right choice of system and taking into account all the processes that occur when a selected source acts on powder materials, unique individual material properties can be achieved. In this work, the influence of powder quality, protect atmosphere as well as processing parameters on the structure and properties of deposited parts manufactured Ti-6Al-4V investigated. Аддитивная технология прямого лазерного выращивания (ПЛВ) относится к классу методов 3D печати металлических изделий. Она является перспективной для изготовления крупногабаритных сложнопрофильных изделий авиационной и судостроительной промышленностей. Методы аддитивного производства диктуют серьезные требования к свойствам используемых порошков, но при правильном выборе системы и с учетом всех процессов, протекающих при воздействии выбранного источника на порошковые материалы можно добиться уникальных индивидуальных свойств материала. В данной работе представлены результаты исследований влияния качества порошков, качества атмосферы и технологических режимов процесса на структуру и свойства конечных изделий, изготовленных методом прямого лазерного выращивания из титанового сплава ВТ6. Кроме того, показана принципиальная возможность повторного использования титановых порошков для достижение более высоких экономических показателей процесса.
