Different procedures of duplicating master cast?

Answer 1

Duplicating a master cast can be achieved through several procedures, including the use of silicone or rubber molds, which capture fine details and allow for multiple reproductions. Another method involves plaster or stone duplication, where a cast is made by pouring material over the master. Additionally, digital duplication techniques, such as 3D scanning and printing, enable precise replication without physical molds. Each method varies in terms of accuracy, cost, and intended use, catering to different applications in fields like dentistry and sculpture.
