Source: author’s photo and elaboration PBF technology is especially suitable for the production of new small parts from metallic materials. This is mainly due to the fact, that during depositing, a layer of powder is melted by laser in the appropriate places, and after deposition, the part is removed from the supports. The main advantage of this technology is that it can deposit any shape with high quality and accuracy. DED technology is used more for industrial applications in the field of forming technology. It seems to be more advantageous when the metal powder is transported to the required place and there the powder is melted by the laser. The melting point is protected by the argon atmosphere. This principle allows the creation of functional edges and layers of tools and repairs without limiting the number of deposits.

Figure 3: The principle of DED

Source: (Ahn, 2021) The principle of DED is shown in Figure 3.This method allows the gradual construction of shapes from different materials, it also allows the local material deposition. This method is suitable both for rapid prototyping and for repairing or depositing more durable materials on functional edges and surfaces.
