3.2.Mesh 3D printed structures have problems with the delamination of individual layers, and this effect should be further investigated in future numerical models. This paper shows the first steps in this direction and therefore introduces finite elements with an average size of 0.4 mm into the model. Fig. 3 presents the mesh of finite elements in the longitudinal section plane at the centre of gravity of the model. It is worth noting in this section that there is a great deal of room for analysis of how to properly model 3D printed elements, especially with respect to the direction and orientation of the print layers.
