Optimization of Fused Deposition Modeling Process Parameters and Dynamic Mechanical Analysis of 3D Printed Polycarbonate/Acrylonitrile-Butadiene-Styrene Composite Loaded with Tetrabromobiphenol-A and Microcrystalline Cellulose

Fused deposition modeling (FDM) was extensively used in manufacturing industries due to its advantages over other conventional manufacturing processes. The process parameters of FDM could influence the mechanical properties and quality of a product. FDM process parameters are optimized using an evolutionary strategy algorithm. Pareto optimal solution was used for investigating the effect of process parameters. Dynamic mechanical testing was performed on the predicted optimal FDM process parameters obtained from the Pareto optimal solutions. Further, the impact of additives on 3D printed PC/ABS (polycarbonate/acrylonitrile-butadiene-styrene) composite blend was investigated. The proposed optimization technique maximizes the storage modulus and minimizes the loss modulus. Experimental results also show that dynamic characteristics such as storage and loss modulus of material satisfy the optimization technique solutions. An increase in storage modulus from 13.6 to 43.7 GPa and a decrease of loss modulus from 7.92 to 1.92 Gpa was noticed with varying tetrabromobiphenol-A (TBBA) and microcrystalline cellulose contents in PC/ABS composite. Also, the results of the damping factor of the material are lower and resulted in the best viscoelastic property of the additive-based PC/ABS composite. Therefore, the developed 3D printed composites are potential applications in the manufacturing industry.
