Summary:There is advance enhancement in fused deposition modeling of 3D printing in which dual extrusion process gives a new approach to fabrication of specimens. Within that, smart materials like fiber/matrix composition give different characterizations to actual material behavior. Compact tension (CT) specimens of commercially available carbon fiber, glass fiber reinforced ABS, and multi-reinforced composites fabricated as per standard are designed with two process parameters of raster and building orientation. With two orthogonal build orientations and three raster angle patterns, it analyzes how it affects the behavior of fracture properties, and especially on fracture toughness of CT specimens. Thereafter, measured fracture properties were used to perform crack growth behavior validation in numerical analysis software which gives strong sight to fracture behavior. In addition, the fracture toughness values for CF-ABS and GF-ABS specimens after testing are analyzed. The present work is proposing a novel way to examine with new approach of additive manufacturing technology.
