In response to the demand for environmentally friendly and sustainable manufacturing processes for intricate castings used in advanced equipment,binder jetting technology has emerged as a leading method for achieving rapid casting design and manufacturing.This technology has attracted much interest from research institutions,universities,and enterprises worldwide.Binder jetting-based sand-mold additive manufacturing can be used to manufacture complex sand molds(cores)directly and does not require traditional molds,expediting the produc-tion of complex castings and the accompanying process refinement.The exceptional design and manufacturing versatility afforded by this technology has enabled a profound transformation in the foundry industry,advancing the digitization,sustainability,and intelligent evolution of sand casting.This paper explores the recent research progress and achievements in the field of binder jetting sand-mold additive manufacturing in four dimensions:materials,design methods,process technologies,and system equipment.Finally,the characteristics and applica-tion advantages of binder jetting technology are analyzed,and the future development trends and challenges of binder jetting-based sand-mold additive manufacturing technology are investigated.
