Improvements on the design of sand structure additive manufacturing

Abstract Additive manufacturing has been widely used in the industry in recent year. Among a range of applications, printing sand structure for casting die or the structure in the construction industry has become more and more popular, since it is cost-effective by using powder printing technology without laser sintering. This paper has explored the additive manufacturing technology used for printing sand structure. To achieve cost-effective and saving materials, methods have been exploring through requirement analysis, materials selection, and design optimization in terms of the mechanical performance of the sand structure. Through 3D modelling, design optimization, and performance improvements, an optimal sand structure for 3D printing is created. This proposed method gives a general way to produce sand structure through 3D printing in the construction and casting industry.
