<p>Advancements in additive manufacturing have intensified the demand for improved printing accuracy and efficiency. Fixed-thickness slicing strategies, prevalent in conventional workflows, are prone to staircase artifacts and perform inadequately when dealing with complex geometries. To address these limitations, an adaptive slicing strategy is introduced, wherein the layer thickness is modulated in real-time according to the angular variation between triangle facet normals and the build direction. Computational efficiency is further enhanced through a topology-aware sorting mechanism that constructs local mesh relationships. Moreover, the integration of NURBS curve interpolation refines slicing contours, yielding reduced surface roughness without compromising geometric fidelity. Simulation outcomes reveal that the approach lowers staircase effects by over 50 %, reduces contour deviations by nearly half, and achieves approximately 40 % improvement in slicing efficiency relative to uniform-thickness methods. These results underscore the method’s potential in advancing high-precision additive manufacturing.</p>
