REBCO high-temperature bulk superconductors demonstrate exceptional performance but face industrialization barriers due to high manufacturing costs. Current batch production methods require optimization in terms of production capacity and cost-effectiveness. This study focuses on process innovation to reduce costs and enhance efficiency in REBCO industrialization. NdBCO/MgO seeds are prepared by the top-seed melt infiltration growth (TSIG) method, with a systematic investigation the doping effects of MgO within the Nd211+0.2BaCuO₂+1%CeO₂+x% MgO system. The results identified an optimal MgO doping content of 16%, which effectively increased the seed melting point by 11.8 ℃ to 1102.3 ℃. Through natural cleavage, high-melting-point NdBCO/MgO seeds were obtained. By integrating the seeded melt growth (SMG) technique with the innovative “stacked architecture” design, efficient batch production of YBCO superconductors is achieved. Additionally, the solid-phase seed wrapping technique is implemented to relax the stringent requirements for seeds, enabling more flexible processing conditions. Performance characterization of YBCO samples show that for triple-layer samples (28 mm diameter, S1/S2/S3) prepared by the stacked architecture, the average maximum trapped magnetic field (B_mtr) values are 0.35 T, 0.39 T, and 0.40 T, respectively, with an average trapped field ratio exceeding 76%; the average maximum levitation forces (F_max) are 62.5 N, 73.2 N, and 75.5 N. Scanning electron microscopy (SEM) is used to observe the microstructure and elucidate the influence mechanism of the “stacked architecture” on sample performance. In conclusion, the innovative stacked architecture for batch fabrication of YBCO bulk superconductors significantly improves production efficiency while maintaining excellent performance.
