**4. Conclusion**

Additive manufacturing is of profound interest for various industries. However, a large number of parameters that affect the quality of the final product limit the application at the moment. Including the initial powders properties have a significant influence on the quality L-DED materials. For the L-DED technology, powders manufactured by gas atomization, plasma atomization, and PREP technologies are most widely used. GA powders have a high amount of satellites on the surface, which can lead to porosity in as-deposited samples. Also, a deviation from the required chemical composition has a significant impact on the properties of products. Light impurities also affect the properties of the L-DED material.

To minimize the amount of rejects due to the properties of the powder, the main requirements for powders and the input control measures that must be implemented are considered.

Considering the high influence on the structure and properties of the material of the initial quality of the powder, a method for the input control of the powder is being developed.

Input control of powder for use as feedstock in L-DED technology includes: Particle size measurement (determination of particle size distribution).

Powder Fluidity Determination.

The totality of implementing measures to control the quality of the powder will reduce the number of defective products.
