### Mechanical Properties of the SLA 3D-Printed and Tensile-Tested ABS-like Resin Specimens
Figure 10: The tensile strength–strain curves for ABS-like resin specimens produced using SLA 3D printing with a 100% infill density (referred to as Case 4). The average strain value exhibited a 25.30% increase in SLA 3D-printed ABS material specimens with 100% infill density as opposed to those with 30% infill density (refer to Table 9 and Figure 11b). The data emphasizes a substantial 25.30% rise in nominal strain at break for SLA 3D-printed ABS-like resin specimens with 100% infill density, in contrast to those with a 30% infill density, as illustrated in Figure 11c. This improvement underscores the heightened flexibility and durability achieved with higher infill densities in SLA 3D printing. This advancement has broad implications, particularly in applications requiring materials to endure deformation and stress without failing structurally. Components with full infill density exhibit greater resilience, allowing them to withstand more significant strains, thereby expanding their potential applications in engineering and design. The same pattern was observed in the average Young's modulus, as depicted in Figure 11d. When examining SLA 3D-printed ABS-like resin samples, those with a 30% infill density exhibited an average Young's modulus that was 22.88% lower than that of SLA 3D-printed ABS-like resin specimens subjected to tensile testing, which had a 100% infill density. Utilizing the data from Table 9 and applying Equations (1) and (2), the maximal displacement and maximal force at break for the SLA 3D-printed ABS-like resin specimens are calculated. The results for the average maximal displacement and average maximal force at break are presented in Table 10 and Figure 12.  
Based on the data presented in Table 10 and Figure 12, it is evident that the average maximum displacement exhibited a substantial increase of 38.92% in SLA 3D-printed ABS-like resin specimens with 100% infill density when compared to ABS-like resin specimens with 30% infill density (as depicted in Figure 12a). Additionally, as indicated in both Table 10 and Figure 12b, the average maximum force at the point of break decreased by 22.88% in Case 4 when compared to the value observed in Case 3. Comparing the average tensile strengths, it is evident that the SLA 3D-printed ABS-like specimens with 100% infill density surpass the manufacturer's specified values for ABS-like resin by about 0.76%, as demonstrated in Figure 13a. Similarly, when scrutinizing the examination of [PERSON]'s modulus in relation to the manufacturer's specified values for ABS-like resin and the results obtained from testing the SLA 3D-printed ABS-like specimens with 100% infill density, a discernible pattern becomes apparent. The SLA 3D-printed ABS-like specimens impressively achieve a striking 99.33% of the values established by the resin manufacturer (Figure 13b). These results underscore the exceptional precision and reliability of SLA 3D printing in producing ABS-like components that closely align with industry standards, demonstrating its suitability for applications demanding consistent and high-quality material performance.
