Description
Summary:Energy metrics in 3D-printing technologies are of major importance for sustainable manufacturing. The printing parameters (PP) affect the energy consumption remarkably and define the overall Energy Printing Consumption (EPC), the Specific Printing Energy (SPE), and Specific Printing Power (SPP). This study investigates the impact of six PPs: the infill raster density (ID), raster deposition angle (RDA), nozzle temperature (NT), fused filament printing speed (PS), layer deposition thickness (LT), and bed temperature (BT), on the above three energy indexes, i.e. the EPC, SPE, and SPP. The experimental course follows the Taguchi L 25 orthogonal array (OA) with six repetitions. The experimental data were dissolved and studied utilizing descriptive statistical tools, i.e. main effect plots (MEP plots), ANOVA, and response surface methodology (RSM). Six evaluation experiments validated the extracted quadratic regression models (QRM). The above statistical models thoroughly describe the effects of six intended fused filament fabrication (FFF) printing parameters on the energy metrics (EPC, SPE, and SPP). Additionally, the physical mechanism is explained in depth by applying mechanical strength evaluation tests for all ranges of parameters' values. This study proposes a methodology for efficient and sustainable FFF.
