Abstract

The core of the present work is the studies of effects of porosity on mechanical properties and specific strength of monolithic carbon fiber reinforced PLA and ABS components fabricated using additive manufacturing technique. Additive manufacturing (AM) technologies have been successfully applied in various applications. Fused deposition modeling (FDM), one of the most popular AM techniques, is the most widely used method for fabricating thermoplastic parts those are mainly used as rapid prototypes for functional testing with advantages of low cost, minimal wastage, and ease of material change. The specimen is prepared as per the D638-1 „Dog Bone? ASTM standards, the chosen FDM process parameters are fill density with 20, 50 and 80(%), print speed with values of 40, 60 and 80(mm/min), and layer thickness 100, 150 and 200(microns). This paper is going to present FDM of ABS and PLA and test if adding carbon fiber (different mechanical parameters) to improve the mechanical properties of FDM-fabricated parts. This proposed research work is useful to decide the effective FDM process factors and their working ranges to manufacture the (ABS and PLA) with carbon fiber components or parts. The results were showed that Tri-hexagon is the combination of triangular and hexagon pattern, which give better results, compare to triangular infill pattern, the 20% and 50% tri-hexagon pattern had the highest UTS to weight ratio. This work is aimed to improve the present conventional manufacturing process and boost the concept and methodology of Additive Manufacturing Technique which will enhance the capability for fabrication of complex geometry and with more degree of freedom. Also various domains of medical, pharmaceutical and defence can greatly be helpful with this technology in improving the present infrastructure and cater the needs of our motherland.
