Abstract
Sand mold 3D printing technology has significantly enhanced the manufacturing capability and production flexibility of complex castings through its digital mold-free forming process.This study systematically examined the technology's core principles,application areas,and comparative advantages over traditional sand casting,with a focus on its technical strengths in fabricating intricate structures,enabling customized production,and facilitating collaborative R&D.The research indicated that the technology can reduce sand mold production cycles by 70％while achieving a material utilization rate exceeding 90％.However,barriers to industrial adoption persist,including high equipment investment costs(over 3 million RMB per unit)and a lack of standardization.Compared to conventional casting methods,the sand mold 3D printing technology,by virtue of its mold-free characteristic,reduces small-batch production costs by up to 70％,yet its economic viability for mass production remains unproven.Future advancements should prioritize intelligent algorithm optimization,development of cost-effective domestic equipment,and cross-industry collaboration to transition 3D printing from"innovative demonstration"to"large-scale application,"thereby providing critical support for the high-end and sustainable transformation of the foundry industry.关键词
