## 4 Discussion  
The application of the proposed design methodology in practice confirmed its effectiveness at the component development stage. To a large extent, the results and the proposed methodology were positively influenced by the _Mesh_ analysis. The implementation of the given procedure in the component design process demonstrated significant savings in development time and component weight with AM orientation. From this, other conclusions are drawn that the departure from traditional design methods or the use of innovative approaches has a significant impact on the overall development. Of course, it cannot be forgotten that the use of advanced design methods and their development is greatly influenced by the production method. AM and DfAM have a directly proportional progress and development curve. The methodology in question is relevant and significant results are only achievable when using AM, as it is not possible to exploit the maximum potential of DfAM (TO) with conventional manufacturing technologies.

Table 1: _Cont._Important questions include why TO principles are not used extensively in design and why the procedures are not used extensively in practice, as they are long-known methods of design. This is due to the relatively difficult operation of optimization software, its reliability and the lack of trained and experienced personnel. Another cause or constraint is the lack of production lines using AM and the price range of products in high-volume production. The aim of this research was to prove the effectiveness of the proposed design solution, as mentioned above, and its implementation in practice to reduce the mentioned negative factors, especially in terms of trained personnel and operator mastery.  
Another research activity is the development of variant design methodologies tailored for the design process of specific product lines, as each component and part exhibits different factors affecting the effectiveness of the design process and its procedures.
