The main purpose behind this project is "Test the natural frequency of the polymer composite with varying critical parameter'' composites 3D printing also known as additive manufacturing or rapid prototyping, is a popular manufacturing method used for creating prototypes in various industries such as aerospace, defence, medical, and automotive. Fused Deposition Modeling (FDM) is a commonly used 3D printing technique that involves adding melted material layer by layer. FDM has several benefits over traditional manufacturing methods and various parameters such as speed, layer thickness, and nozzle diameter need to be considered while setting 3D printing options. PLA is widely used filament material for 3D printing, but it has drawbacks such as low toughness and flexibility. To overcome these composites are used, such as wood-PLA. PLA is degradable material hence it is used with other natural fibres. The 3d printing material is printed into a combination of varying parameters like speed and nozzle as (60, 80, 100) mm/sec and (0.4, 0.6, 0.8) mm respectively. The infill density and temperature is kept at 100% and 2100C respectively. For this we have used Taguchi technique L9 Orthogonal array. Further vibration analysis test is carried out, by this we will find natural frequency. Hence most affecting parameters are finalized and optimum combination parameters are selected.
