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 was investigated. In addition, it was shown the fundamental possibility of using recycled titanium powders to achieve higher economic performance of the process.
