| Abstract Scope |
This research will be focused on optimizing printing parameters using the response surface (RS) methodology. If the printing parameters are not optimized, the resulting prints will contain an unacceptable surface finish or porosity, or incomplete print as the lower portion of the print must withstand the weight of each consecutive layer. Layer height and percent infill will be adjusted for the study while volumetric flowrate and print head speed will be held constant. RS is a statistical based process that uses multiple data points of a curve and regression to determine local maxima or minima. For this study, RS will be used to identify the inflection point where density is maximized. A local starting point for the parameters begins with the material rheological characterization and geometric modeling or brute force method. Once the parameters are close, the RS approach will be used to refine printing parameters. |
