Resin casting is a technique used to create props, replicas, and decorative items by pouring liquid plastic materials (resins) into molds. It's commonly used in prop making, cosplay, and special effects industries to produce multiple copies of items or create unique pieces. Think of it like making ice cubes, but instead of water, artists use special plastics that harden into durable objects. This process allows makers to create everything from small jewelry pieces to large costume armor parts. Similar techniques include injection molding or 3D printing, but resin casting is preferred for its detail quality and ability to make multiple copies quickly.
