Abstract— To increase the efficiency of technical preparation for the production of components produced by additive technologies, the importance of simulation and optimization processes is growing already in the phase of the design solution. The article aims to introduce the method and demonstrate the process of component optimization, based on the application of the results of simulation methods verification. The available technology is a method of applying molten polymer-based material in layers - FDM (Fused Deposition Modeling). It is possible to produce a part of a rather complex shape in this way. An attribute of the method is the relatively low strength, given by the characteristics of the material used in connection with the production method. To achieve good functional properties of the component, topological optimization can be applied in its design and preparation of production technology. Topological optimization of a part made by the FDM method from a frequently used ABS (Akrylonitrilbutadienstyren) material is performed based on a simulation of the mechanical load of a defined component. The aim is to achieve acceptable mechanical properties and at the same time, efficient production by 3D printing. The presented procedure can be generalized and applied to components of a similar characterizer and other additive production methods. The principle of the process is the effective deployment of CAD (Computer Aided Design) and CAE (Computer Aided Engineering) tools for preprocessing the part in the design phase.
