5. Conclusion AM technology is very progressive and is gaining an irreplaceable place among technological processes. The usability of AM in industrial practice is highly dependent on the chosen principle of deposition and application itself. Based on the result of this paper, Additive Manufacturing using Directed Energy Deposition proves to be the most beneficial for application in the field of hot forming technology. The presented cutting edge applications were carefully selected mainly from the point of view of comparison with standard technologies, which were made by welding of layers. Evaluation of AM usability takes into account not only the advantages of this technology but also its disadvantages. The biggest disadvantage, which is also the most visible, is mainly the time aspect when the printing times are in the order of hours. The main advantage of AM DED is mainly in higher accuracy in comparison to welding. Moreover, AM reduces the machining time of functional surfaces after deposition, which is problematic for hard materials, and also reduces the amount of material required. Higher accuracy also brings a lower probability of defects in the layer and cohesion between the base and deposited material. Initial comparisons show 3 times longer tool life of the cutting tool with a deposited edge made of NIMONIC in comparison to CAPILLA 66 welds. The test has not been completed yet. The tool for cold cutting sheet metal with a deposited edge made of steel M2 has already 50000 pieces and the test also has not been completed yet.
