Since ancient times humans were trying to create tools and goods based on their functionality and their reduced weight as much as possible. The answer to this design problem was given by the transition from the analog to the digital era, due to the development of computer systems, with the use of topology optimization methods. Through mathematical analysis and algorithmic modeling on digital 3D objects, modern CAD-CAE systems can generate optimal design solutions, that no one could ever imagine. By using the way that nature creates as guidance, topology optimization produces organic geometries as design alternatives to the original model. These designs can harmoniously combine functionality, reliability, and mass minimization. However, the problem that arises at this point is how these complex geometries can take physical form and eventually lead to a final product.The manufacturing process that manages to overcome this obstacle is no other than the additive manufacturing. Based on the idea of building three-dimensional objects through material deposition in layers, this method has the ability to make any digital 3D model “come to life”, regardless of its geometrical complexity. The great advantage of additive manufacturing, in addition to the unlimited design freedom it offers, is the fact that in recent years this method can be used for the production of metal objects and mechanical components.In conclusion, this diploma thesis examines the entire process of metal additive manufacturing. Starting from the stage of the model’s initial design and optimization, utilizing the appropriate software, up to the final stage of its creation using a metal 3D printer.
