Figure 5
This graph shows the relationship between roughness depth denoted as R z in micrometres and layer height, presented as a percentage. The x-axis represents layer height, ranging from twenty to one hundred percent, while the y-axis indicates roughness depth ranging from twenty to one hundred micrometres. Each line corresponds to different strand widths ranging from two hundred to eight hundred micrometres, with various markers and styles indicating each width. The graph includes shaded areas around the lines, representing variability or confidence intervals. The key identifying strand widths is found in the upper left corner, with each line type corresponding to a specific strand width. The data flows left to right along the x-axis and progresses top to bottom along the y-axis, facilitating easy comparison of trend patterns across different strand widths at varying layer heights.Line roughness depth Rz as a function of the ratio of layer height hl to strand width ws for different strand widths/nozzle diameters. The line is the mean with a coloured area for the standard deviation (1σ). Outliers, which were excluded from the statistical analysis, are also omitted
