Verification of stress transformation in anisotropic material additively manufactured by fused deposition modeling (FDM)

The widespread use of additive manufacturing (AM) has been extensively progressed in the past decade due to convenience provided by AM rapid and reliable part production. Fused deposition modeling (FDM) witnessed even faster growth application as its equipment is environmentally friendly easily adaptable. This increased FDM manufacture prototypes finished parts accompanied concerns that 3D printed do not perform same relatively homogeneous produced molding or machining. As interface between two faces bonded material may be modeled stress elements, theory, layers subjected tension at varying angles transformed required break layer bonds can determined. To evaluate such a relationship, this study, stresses calculated from transformation were compared with behavior specimens tensile loads. maximum principal was found constant relative angle, regardless whether specimen experienced failure within material, although 75° load notable exceptions finding. much lower for samples used tests attributed possible environmental factor, temperature humidity change, degrading samples’ structural integrity.
