Description
This study examined how the mechanical characteristics of 3D-printed photopolymer composites are affected by the inclusion of boron nitride (BN). Stereolithography technology was used to print BN-reinforced photosensitive resin composites with different BN weight percentages (0, 0.5, 1.0, and 1.5 wt%). The effect of process parameters - Material composition, build angle, post-curing time, and lift speed) on the tensile strength of the printed specimens were evaluated using a Taguchi L16 orthogonal array. The microstructure and elemental composition of the composites were characterized using energy-dispersive X-ray spectroscopy (EDAX) and scanning electron microscopy (SEM). Tensile tests were performed in accordance with ASTM D638 Type IV, and the findings were assessed using an analysis of variance (ANOVA) and signal-to-noise (S/N) ratio. SEM and EDAX investigations revealed that BN was evenly distributed throughout the photosensitive resin matrix. The ANOVA results showed that post-curing time had the biggest effect on tensile strength (38.283 % contribution), followed by material composition (27.669 %), lift speed (16.265 %), and build angle (17.782 %). For the maximum tensile strength, the ideal set of process parameters was determined to be 1.5 wt percent BN, 90 build angle, 60 min post-curing time, and 60 mm per minute lift speed. Significant interactions between the parameters under study were displayed by interaction plots. This study offers important insights into optimizing SLA process settings for increased tensile strength and shows how BN-reinforced photopolymer composites can improve the mechanical properties of SLA-printed objects.
