Description
The impact strength and hardness characteristics of boron nitride (BN) reinforced photosensitive resin composites made by stereolithography (SLA) 3D printing are examined in this work in relation to the effects of material composition and printing settings. Taking into account the process factors of material composition, lift speed, build angle, and post-curing time, a Taguchi L16 orthogonal array was utilized to optimize the design parameters. Analysis of variance (ANOVA) and the signal-to-noise (S/N) ratio were used to examine the experimental data. Material composition of 1 wt% BN, build angle of 0, post-curing time of 60 min, and lift speed of 30 mm/min were the ideal process parameters for high impact strength, according to the S/N ratio analysis. For high hardness, the ideal parameters were the material composition of 1 wt% BN, a build angle of 90, a post-curing time of 90 min, and a lift speed of 45 mm/min. According to ANOVA results, the build angle had the biggest impact on hardness (56.74%), whereas post-curing time had the biggest impact on impact strength (49.66%). The study also indicates that all parameters should be tuned simultaneously for their combined influence on the mechanical characteristics, according to interaction graphs. 2025 John Wiley & Sons Ltd.
