Abstract
3D printer is a cutting-edge process that manufactures a product directly from a CAD file using a layer-based manufacturing strategy. Fused deposition modeling (FDM) is a 3D printing process that uses a flexible extruder and a heated nozzle to create components. Various process parameters drastically impact the mechanical properties and component weight of printed objects. As a result, improving the mechanical features of printed components requires examining the impacts of input elements and anticipating results by using relevant process settings. The impact of process factors such layer height, print speed, shell count, and fill density on the compressive strength and part weight of products printed from polylactic acid (PLA) via FDM were investigated in this work. The studies employed an L16 Taguchi orthogonal array experimental design to alter the input parameters at various levels. The investigation indicated that shell count and infill density are the most significant factors influencing the compressive strength of PLA components. Printing speed has a negligible impact on printed component part weight, while layer height, shell count, and infill density have a substantial impact.
