用光固化（SLA）打印机以 0.025–0.05 mm 层厚打印辊面花纹模型，打印方向沿辊轴以避免层纹混入纹理；打印件清洗后 405 nm 二次固化 15 分钟，再包埋翻铸为黄铜辊坯，上车床车外圆与轴孔。辊径超过 100 mm 时分段打印后红套组装，接口处按花纹单元对齐拼接。
Print the roller surface model on an SLA printer at 0.025–0.05 mm layer height, oriented along the roller axis so layer lines never contaminate the texture. Wash, post-cure 15 min under 405 nm, then invest and cast into a brass roller blank and turn the OD and bore on a lathe. Above 100 mm roller diameter, print in segments and shrink-fit them with pattern units aligned at the joints. ---
