某馆对高 1.2 m 的人物肖像做手持激光扫描（点距 0.1 mm），逆向建模后按 4% 放大输出分段 3D 打印蜡模，段间以定位销与热熔蜡拼接成整体，再按传统陶瓷壳 8 层挂浆、1150℃ 浇注锡青铜。铸件壁厚均匀控制在 5–6 mm，成品与扫描原型的三维比对偏差 <1.5 mm，仅用 12 天完成传统需月余的复制流程。
A museum scanned a 1.2 m portrait bust with a handheld laser scanner (0.1 mm point spacing), scaled it 4% in reverse-engineering software, and printed segmented wax patterns, keyed and hot-waxed into one body. After 8 ceramic-shell coats the bronze was poured at 1150°C. Wall thickness held at 5–6 mm; 3D comparison against the scan showed deviation under 1.5 mm, completing in 12 days a reproduction that traditionally took over a month.
