AM technology is used in many areas of the nowadays civilization. The leaders of these technology are aerospace and automotive industry because through this is possible to create a special design with very low weight and costs. However, very interesting area is production of the cutting tools. There is possible to use the advantages of the AM technology like production non-traditional shape, special internal cooling systems and their modification and repass of damage tool. With this idea, the special milling head was built. The major advantage of this new generation milling head is the radical reduction of the weight by more than 50% versus standard cutting tools. Final mechanical stability is similar to the full volume body milling head. A further advantage is the possibility of using a special internal cooling system for the clearance and rake faces of the cutting inserts, as in this case. To verify the milling strength and stiffness, FEM analyses were made and the weak points were optimized. After these analyses, the cutting tool was printed and tested. Firstly, material analyses, modal analyses and stability analyses were carried out, and subsequently a long-term test was conducted. Before of all the big material research of 3D metal printing were made. The grain size and chemical quality analyses of the input material were made and the mechanical properties was evaluated too with the different setup.
