This paper presents all activities in the Additive Manufacturing area in COMTES FHT. The COMTES FHT focuses on topological optimization, structural analysis, thermal analysis and numerical simulation of AM process, additive manufacturing, mechanical testing and metallographic evaluation of deposited samples and components. The function edges and layers on tools for forging and forming made by AM will be presented in this paper. Keywords: deposition, additive manufacturing, closed die forging, open die forging, tools JEL Classification: I230, O310, L740 1. Introduction At present, additive manufacturing is increasingly expanding in industrial applications and a relatively large number of institutions are studying this issue. It can be stated that the initial estimates of how this new technology will affect manufacturing capabilities and the general industry have not been confirmed. Based on the growing knowledge of these technologies, it appears that they will take up a very specific position among the standard manufacturing technologies and will complement them in an appropriate way. In our company, we deal with not only research and development in AM technologies area but the possibilities of applying AM technology in common technological procedures. The benefit of AM technology is mainly in the fact that it allows you to make a part of a general shape, which would be very difficult to produce in the usual way or would be high material consumption. 2. Additive manufacturing Several technologies are used for additive manufacturing, which is generally divided according to the source of thermal energy and the type of input material. According to this principle, it is possible to identify seven types of AM technology, as shown in Figure 1, which was published in 2017.
