This suggests that the layer height setting may influence the consistency and accuracy of the printed objects. A table (Table 9) of values was constructed based on the analyzed data, offering a detailed analysis of the data. It can be determined from this analysis that optimizing the layer height is key to minimizing errors and improving the quality of the final 3D-printed objects. This methodical approach allows for the precise configuration of the printing apparatus and the optimization of the printing process, thereby ensuring the production of the highest-quality final products.

Figure 13: Box plot summarizing data collected for samples printed with varying layer height settings. The final evaluation of the measured values for the outer perimeters of samples printed at different speeds, temperatures, and layer heights reveals several key aspects, which will be discussed in the following paragraphs. A total of 17 samples were subjected to analysis, with each sample printed using a distinct set of settings. An examination of the print speed plots revealed that varying speeds (from 50 mm/s to 350 mm/s) exert a significant influence on the consistency of the outer perimeter. The findings suggest that higher print speeds result in greater oscillations, indicating that lower speeds may be more conducive to achieving greater accuracy and consistency. The analysis of the printing temperatures (ranging from 190 to 270 degrees Celsius) revealed a significant impact on the consistency and quality of the printed objects. Higher temperatures led to greater oscillations and inconsistent results, while lower temperatures resulted in more stable perimeter values. Additionally, a detailed examination of the layer height (from 0.08 mm to 0.39 mm) showed that adjusting this parameter significantly affects the outer perimeter, with higher layer heights causing notable oscillations and inconsistencies. This suggests that optimizing the layer height is crucial for achieving superior quality in final products. The final evaluation indicates that the meticulous optimization of the printing speed, temperature, and layer height is imperative to minimize errors and enhance the quality of 3D-printed objects. It is therefore evident that the consistent and accurate adjustment of these parameters is essential to achieve high-quality results. This research was conducted to identify errors in 3D printing, with a particular focus on the setting of critical printing parameters. The experimental results, obtained using a Keyence laser scanner and microscope, demonstrated that the samples exhibited minimal imperfections. Box plots were employed to obtain data for a statistical analysis of the indices obtained for each printed sample. Based on our analysis of the data, we compiled a table (Table 10) of the minimum deviations for each of the critical print parameters. The data were subjected to analysis, which revealed that the samples printed with the optimal parameters exhibited the least variation. As can be observed from the table, the lowest minimum range deviation (min. range (R)) was observed for the change in the layer height (Sample 3: 0.16 mm), with a value of 0.007392462. When the printing temperature was modified (Sample 4: 250 \({}^{\circ}\)C), the minimum range deviation was 0.018802606, and \begin{table}
