Ningbo Zhongke Xianglong Lightweight Technology Co., Ltd. focuses on design for additive manufacturing (DFAM) as its core technical direction, integrating AI design tools, topology optimization, and generative design methods to build a full-stack technology chain of 'design—process—manufacturing—validation'. Since establishing operations in Ningbo Qianwan, the company has collaborated with multiple core central aerospace enterprises and commercial aerospace firms, achieving an annual production capacity exceeding 10,000 parts with a yield rate of 98.7%. Through composition optimization and atomized powder technology, it has successfully reduced nickel-based alloy costs by 37% and developed a titanium-aluminum gradient composite material with a density reduction of 28%. Leveraging its accumulated expertise in selective laser melting (SLM) technology, the company has developed the engineering capability to handle over 100 product designs annually. Recently, it won the 'Best Cooperation of the Year Award' from Beijing Southern Sneema (a joint venture between Safran and AVIC). Zhongke Xianglong's development path, with DFAM-driven design as its core competitiveness, represents the evolution of metal 3D printing from 'equipment-driven' to 'design-driven'.
