摘　　要：3D打印机成本和打印材料价格逐渐降低、模具打印填充率为20%的设置下,相比制作木模等辅助件,3D打印的成本大大降低。3D打印技术可以与砂型铸造完美结合,尤其在中小批量及产品个性化方面具有独特的优势,且成本较低。本工艺研究针对水枪扳机铸造困难且成型精度难以保证的缺点,运用3D打印技术成型快、制作精良等特点,进行辅助件设计,大幅度缩短铸造时间,提高铸件成型效率。When the cost of 3D printer and the price of printing materials are gradually reduced and the filling rate of mold printing is 20%,the cost of 3D printing is greatly reduced compared with making auxiliary parts such as wooden mold.3D printing technology can be perfectly combined with sand casting,especially in small and medium batches and product personalization,with unique advantages and low cost.This process research aims at the shortcomings of water gun trigger casting difficulty and difficult to guarantee the molding accuracy.It uses 3D printing technology to form fast and well-made,and performs auxiliary parts design,which greatly reduces the casting time and improves the casting molding efficiency.
