Additive production is a relatively new concept that has an increasing influence in the field of mechanical engineering. We divide it into a number of different technologies. The choice of individual technology depends on the requirements of the final product and the financial resources of the individual. In this paper, we discussed the existing technologies of additive production among all existing ones, and we went deeper into the FDM technology of 3D gear printing and their advantages/disadvantages. We found out what we need to pay special attention to when constructing gears intended for 3D printing. At the very end, we also made a useful product that contained printed gears and presented all the intermediate steps from the idea to the final product.
