The values of Samples 1 (blue) and 5 (purple) span a range from approximately 0.326 mm to 2.3223 mm. This suggests that the greatest discrepancies are observed at temperatures approaching 270 \({}^{\circ}\)C.  
Consequently, the box plot illustrates the ranges of values and deviations, thereby enabling a comparison of the consistency of the individual samples. A table (Table 8) of values was constructed from these data, offering a detailed analysis of the data. Furthermore, the graph enables the extraction of the maximum and minimum values, which also allows for the overall range of the values to be observed. The data allow for the optimization of the printing temperature parameters to achieve the best quality of the final products. The data indicate that the printing temperature had a significant impact on the consistency of the outer perimeters of the printed samples. Lower temperatures resulted in more stable out

To optimize the printing process and achieve high-quality final products, it is therefore advisable to select lower printing temperatures. The subsequent graph (Figure 12) illustrates the recorded outer-perimeter values for samples produced with varying layer height settings. The X-axis represents the measurement values (1 to 1000), which correspond to individual points on the outer perimeter of the sample. The height values, expressed in millimeters (1.9 mm to 2.25 mm), are represented on the Y-axis. The seven distinct samples are represented by different colors. The samples are identified as follows: Sample 1 (blue); Sample 2 (orange); Sample 3 (green); Sample 4 (light blue); Sample 5 (purple); Sample 6 (light green); and Sample 7 (dark blue). The range of values observed in Sample 1 (blue) spans from 2.0 mm to 2.0425 mm, exhibiting distinct and regular oscillations. This indicates that the perimeter height is inconsistent. Sample 2 (orange) exhibits a range of values from 2.09 mm to 2.1315 mm, with less pronounced oscillations than those observed in Sample 1. Sample 3 (green) exhibits a range of values from 2.0 mm to 2.0318 mm, displaying regular, moderate oscillations. Sample 4 (light blue) exhibits a range of values from 2.0683 mm to 2.1893 mm, with slight oscillations and a consistent range. Sample 5 (purple) exhibits a range of values from 2.05 mm to 2.188 mm, with a few significant oscillations present. Sample 6 (light green) exhibits a range of values from 2.0 mm to 2.0583 mm, with moderately significant oscillations. Sample 7 (dark blue) exhibits the most pronounced oscillations, with a range of values from 2.0248 mm to 2.1898 mm, and is therefore the sample with the largest range of values.

Table 8: Table comparing statistical indicators of samples printed with different temperature settings. The box plot (Figure 13) provides an overview of the total range and outer-perimeter variations for each sample. From the plot, different layer height settings have a significant effect on the consistency of the outer perimeter. The data indicate that higher layer values, as observed in Samples 1 and 7, exhibit significant oscillations.
