Paragraph starter

The additive manufacturing of polymeric composites, particularly through material extrusion techniques like FDM, is significantly influenced by the layup sequence and orientation. Research indicates that uncontrolled printing layups can lead to interlaminar damage, compromising mechanical performance. Conversely, a deliberate control over layer orientation and printing direction can achieve a more homogenous distribution of transverse loads, thereby maximizing the load-bearing capacity of the printed component. This highlights the critical role of layup strategy in tailoring the mechanical properties of 3D printed composites for specific functional requirements.
