在矿井RTV（室温硫化）加工过程中，液体硅胶rubberis倒了主图案周围。 主模式/模具通常originatesfrom立体光刻技术作为SL生产树脂部件accuracywhich高度能够展示机械配合和功能。 SL部分arefinished以高标准打造工具的主人。

Theresulting模具从图案拉/剪切和固化，然后接着usedto铸造氨基甲酸酯份。 该方法的主要优点是能够toobtain更高量的原型的相对低的成本。

• 功能原型和可视化的模型具有良好的细节和表面光洁度

• 铸造聚氨酯的刚性，耐温性，颜色和质地的范围很大

• 可用于在某些情况下低运行生产

• 交付的一部分（S ）一般在2 - 3周

Inthe RTV (Room Temperature Vulcanized) tooling process, liquid silicone rubberis poured around a master pattern. The master pattern/ mold usually originatesfrom Stereo Lithography as SL produces resin parts to a high degree of accuracywhich is capable of demonstrating mechanical fit and function. SL parts arefinished to a high standard to create tooling masters.

Theresulting mold is pulled/ cut from the pattern and cured, then subsequently usedto cast urethane parts. The key advantage of this process is being able toobtain higher quantities of prototypes at relatively low cost.

• Functional prototypes and visual models with good detail and surface finishing

• Cast urethanes ranging greatly in rigidity, temperature tolerance, color and texture

• Can be used for low-run production in certain situations

• Delivery of part (s) usually in 2 - 3 weeks
