用 SLA 打印 0.03 mm 层厚的纹样母版，酒精清洗 10 分钟后 405 nm 二次固化 15 分钟；喷 2–3 遍灰底漆填补层纹、干燥 2 小时，再涂脱模剂浇注 RTV 硅胶。母版悬垂处加 1.5 mm 排气支撑，支撑点应置于纹理背面或非视觉区，打磨后不留痕迹。
SLA-print the pattern master at 0.03 mm layers, wash 10 min in alcohol and post-cure 15 min under 405 nm. Spray 2–3 coats of grey primer to fill layer lines, dry 2 h, apply release agent, then pour RTV silicone. Add 1.5 mm venting supports on overhangs, placing support points on the back or non-visible areas of the pattern where polishing leaves no trace. ---
