“…[48] studied the effect of three major process parameters such as layer thickness, infill density, and raster angle on mechanical properties of ABS using RSM and analyzation tool was used MINITAB [14], [49] and concluded these mentioned parameters have great influence the mechanical properties. Researchers have created a dog bone and notched FDM based 3D printed sample to determine the optimum values of printing parameters for superior mechanical properties [23], [24], [44], [50]. The selected parameters were infill density, print bed temperature, and layer thickness and mechanical properties were investigated with the influence of mentioned parameters with the help of RSM [4]- [6], [41], [48].…”

Purpose: In the present work significant process parameters (nozzle temperature, layer thickness, and printing speed) are optimized for enhancing the mechanical properties of fused deposited PLA specimens. The selected parameters in this study critically impact the desired mechanical properties of printed PLA parts. Design/ Methodology/ Approach: The three selected critical process parameters are simultaneously studied in a systematic manner using a hybrid statistical tool central composite design (CCD) for Response surface methodology. The selected printing parameters are layer thickness, nozzle temperature, and printing speed. Findings: The best composition of the tensile strength (50.5479 MPa) & flexural strength (95.0163 MPa) has been produced with an RSM predicted model having process parameters layer thickness 0.2313mm, nozzle temperature 208 °C, and printing speed 55.5 mm sec-1 Based on the results of the validating method, by producing an optimal sample in accordance with optimal parameters and their mechanical properties measurements, it was found that the optimal values of parameters are giving the maximum mechanical properties and the RSM Method has a high ability to optimize the parameters. Research Implications: Tensile Strength and Flexural strength are the two important features that need a stent to withstand the forces exerted on it by the surrounding tissues and blood flow and to be able to bend and conform to the shape of the artery during insertion and deployment. This study focuses on nozzle temperature, printing speed, and layer thickness in the experimental estimation of the ideal PLA polymer FDM part characteristics. Results show that Layer thickness and Nozzle Temperature are the dominating contributors to the mechanical responses (tensile strength & Flexural strength).

Many difficulties surround the heating characteristics of brakes when it comes to their creation, including contact region features, material choice, development of hot spots, associated physical geometry, and deformations, as brakes are subjected to continuous operation. Therefore, it is must for all vehicles to have proper brake system. In this report there is the modification of the disc and that results in the design are used to carry out analysis on it. The analysis of standard disc brake model and new design using in Ansys is done the Thermal analysis and Modal analysis also calculate the deflection and Heat flux, Temperature of disc brake model. Understanding the different forces (action and friction) which are acting on the disc brake, as well as how the disc brake operates more efficiently, will assist to reduce the number of accidents that occur each day. The primary goal of this research is to examine the brake disc's thermo-mechanical behavior during braking. The disc material is changed to carbon-ceramic, and the results of the FEA of the new design disc are used. This study presents the findings and the disc's future prospects.
