  Enhancement of Flexural Strength in FDM-Printed Components through Taguchi-Based Process Parameter Optimization

  By PVR Girish Kumar, R. Sudarshan, B. Srinivas Reddy, K. Satish Babu

  Abstract: Additive manufacturing (AM), especially Fused Deposition Modeling (FDM), has emerged as a widely adopted and versatile method for producing three-dimensional components. The process involves the deposition of a thermoplastic filament in a semi-molten state, which solidifies in successive layers to form the final structure. While this method enables the production of complex geometries at relatively low cost, the printed parts often exhibit inferior surface quality and reduced mechanical performance compared …

  AL6061/Al2O3-Ash Reinforced Composites: An Experimental and Statistical Study Using Ultrasonic Stir Casting

  By M Naga Phani Sastry, K. Devaki Devi, Borigorla Venu, PVR Girish Kumar

  Abstract: This study presents an experimental investigation on the influence of fly ash particle size on the mechanical properties of aluminum alloy (Al6061) composites fabricated through Ultrasonic Assisted Stir Casting. Fly ash, a low-cost and low-density by-product of thermal power plants, has emerged as an effective reinforcement material due to its excellent fluidity, high filling capability, and ease of processing. It has been increasingly utilized in metal, polymer, and rubber composites …
