Advanced methods for manufacturing high quality parts should be used to ensure the production of competitive products for the world market. Investment casting (IC) is a process where a wax pattern is used as a sacrificial pattern to manufacture high precision casting of solid metal parts. Rapid casting is in turn, a technique that eases the IC process by combining additive manufacturing (AM) technologies with IC. The use of AM technologies to create patterns for new industrial products is a unique opportunity to develop cost-effective methods for producing investment casting parts in a timely manner. Particularly, stereolithography (SLA) based AM is of interest due to its high dimensional accuracy and the smooth surface quality of the printed parts. From the first appearance of commercially available SLA printers in the market, it took a few decades until desktop SLA printers became available to consumers at a reasonable price. Therefore, the aim of this review paper is to analyze the state-of-the-art and applicability of SLA based 3D printing technology in IC manufacturing, as SLA based AM technologies have been gaining enormous popularity in recent times. Other AM techniques in IC are also reviewed for comparison. Moreover, the SLA process parameters, material properties, and current issues are discussed.
应采用先进的高质量零件制造方法，以确保生产出具有全球市场竞争力的产品。熔模铸造（IC）是一种以蜡模作为牺牲模来制造实心金属零件高精度铸件的工艺。快速铸造则是一种通过将增材制造（AM）技术与熔模铸造相结合来简化熔模铸造工艺的技术。利用增材制造技术为新工业产品创建模具，是及时开发具有成本效益的熔模铸造零件生产方法的独特契机。特别是，基于立体光刻（SLA）的增材制造因其高尺寸精度和打印零件的光滑表面质量而备受关注。从市场上首次出现商用SLA打印机，到桌面型SLA打印机以合理价格面向消费者，花了几十年时间。因此，鉴于基于SLA的增材制造技术近年来广受欢迎，本综述论文旨在分析基于SLA的3D打印技术在熔模铸造制造中的现状和适用性。还对熔模铸造中的其他增材制造技术进行了综述以作比较。此外，还讨论了SLA工艺参数、材料特性和当前存在的问题。
