Abstract
The chapter presents the basic aspects of the use of metal powders in one of the main additive technologies—direct laser deposition (DLD). Direct laser deposition refers to a group of direct energy deposition (DED) methods and is analogous to Laser Metal Deposition (LMD) technology. The main requirements applied to DLD used metal powders are analyzed and substantiated. The influence of the basic properties of the powders on the quality of the deposited samples is demonstrated. An example of incoming quality control of powders, allowing its application in DLD technology, is presented. The results of experimental research on obtaining quality control samples for the most used metallic materials are presented. The results of structure and properties studies for the main groups of alloys based on iron, nickel, and titanium are shown. The potential for manufacturing products for various areas of industry using DLD has been demonstrated.
