<![CDATA[Advances in additive manufacturing technology, particularly the Stereolithography (SLA) method, are increasingly being utilized across various industrial sectors due to their ability to produce components with high dimensional accuracy, good surface quality, and complex geometric details. However, the quality of the printed results is significantly influenced by process parameters and post-processing steps, necessitating the optimization of appropriate parameters. This study aims to analyze the effect of variations in printing and post-processing parameters on mechanical characteristics such as surface hardness, surface roughness, and dimensional accuracy. Parameter variations include print orientation (horizontal, vertical, diagonal), layer thickness (0.2 mm, 0.25 mm, 0.3 mm), and normal exposure time (5, 10, 15 seconds) using Translucent Green ECO Resin material on an Anycubic Photon Mono 2 machine. The best hardness test value was obtained at the specification parameters of horizontal print orientation, layer thickness 0.25 mm, and NET 10 seconds with the highest average hardness value of 79.1 HD. The highest accuracy was achieved by specimens with horizontal orientation (H), layer thickness of 0.25 mm, and exposure time (normal exposure time) of 10 seconds, which recorded the lowest deviation value of 0.298. Horizontal orientation combined with a layer thickness of 0.25 mm and a normal exposure time of 10 seconds produced the best surface quality with the lowest roughness value of 1.890 µm. Future works should investigate the combined effect of post-curing temperature, UV intensity, and artificial intelligence-based optimization to further improve the performance of plant-based SLA resin]]>
