In recent years, structural optimization of objects has noted remarkable progress, due to the rapid technology growth and the development of design methods. Designing optimized parts is a constant requirement for businesses and is accelerated by the development of new production processes that radically change the way in which all components/products are produced, both for complex products and for simple everyday objects. Required factors, such as manufacturing lightweight structures, saving materials, reducing time for production and entry into the market, affect both the time and cost of the object being produced.This paper is related with optimization methods and the way in which they optimize the original geometry of a model. Furthermore, lattice structures will be mentioned and how they are inserted suitably in a topology optimization solution of a problem. Most of the time the design which results from all these processes consists of very complex structures that cannot be manufactured with conventional production methods. This is not a disadvantage though, as during the optimization it is taken into account that the model will be produced via additive manufacturing processes, like 3d printing. Therefore, the optimized model is eligible for direct production. A software package which includes the aforementioned techniques and will be used for the needs of this paper is Siemens NASTRAN NX 12. In conclusion, the ultimate goal for this paper, besides familiarizing with one of the advanced techniques in the field of design, the topology optimization method in conjunction with lattice structures, is also the interpretation of the obtained results.
