What is FDM Sandwich Specimens: Stiffness Evaluation about?

This technical paper evaluates the stiffness and strength of fused deposition modeling (FDM) 3D printed sandwich structures with different raster orientations in each layer. Specimens with various sandwich-like configurations were printed and tested in tension and bending. The results found that sandwich structures with differing raster orientations in adjacent layers had higher or equal stiffness than the default FDM configuration. However, the classical lamination theory model did not accurately predict t
