The elastic response of arc structures fabricated using curved-layered fused deposition modeling was studied using the finite element method, focusing on the influence of structural parameters such as subtending angle, overlap between layers, and relative density. The study found that the overlap between layers had a high influence on the mechanical response of such structures. Experimental results showed good agreement with the stiffness range predicted by the FEM model, with microstructural characterization revealing more defects for higher lattice porosity values, affecting structural properties.
The elastic response of arc structures fabricated using curved-layered fused deposition modeling was studied using finite element method (FEM). The influence of structural parameters, such as subtending angle, overlap between layers and relative density on the mechanical response of such structures was studied. The results obtained showed high influence of the overlap between layers. The FEM model predicted a range in which the stiffness of such structures can lie. This was compared with experimental results, showing good agreement. The samples were further characterized microstructurally, revealing more defects for higher values of lattice porosity, affecting the structural properties.
