Electrospinning is a fiber fabrication technique that enables the production of micro- to nanoscale fibers and has been widely utilized in various applications. Although recent studies have explored electrospinning-based three-dimensional additive manufacturing, most efforts have focused on planar structures, resulting in limited demonstrations of complex three-dimensional architectures. In this study, a hybrid additive manufacturing system was proposed by integrating electrospinning with in-situ UV laser curing and a precision motion-stage control strategy. Two photocurable polymers with different stiffness were examined, and key process parameters—including collector speed, laser power, applied voltage, and nozzle inner diameter—were systematically analyzed and optimized with respect to their influence on fabrication quality. Based on the optimized conditions, various three-dimensional structures such as micro-pillars, micro-pillar arrays, inclined pillars, vertical spring structures, and spindle-knot pillars were fabricated. The structural stability, and repeatability of the fabricated geometries were evaluated, confirming that the proposed hybrid system enables the reliable and repeatable fabrication of complex three-dimensional structures using both rigid and flexible materials.
