In partnership with:
In February 2015, 3D Matter conducted a study on infill %, layer height, and infill pattern. We wanted to continue this initial effort by studying another set of very important FDM 3D printing parameters: filament color, printing speed, extrusion temperature and ageing. These are parameters that 3D printer users have frequently singled out as making a difference on the outcome of prints. So the goal of this study is to distinguish the factors that have a large influence on the printed parts from those that have limited influence. This helps users optimize their prints by focusing on the important parameters.
In the main body of this study, we provide a detailed description of the influence these four parameters have on mechanical performance: max stress, elongation at break, and rigidity (Young Modulus). We also evaluate the influence of the parameters on the visual quality of printed objects.
