After the desired thickness is achieved, the excess slurry is poured out, and the mold is allowed to drain and dry. This agility is invaluable for prototyping and small-batch production, where the cost of traditional tooling is prohibitive.

The slip is poured slowly to minimize air entrapment, ensuring that the liquid fills all the细微 details of the pattern. The duration of the slip’s contact with the pattern, known as the dwell time, determines the wall thickness of the final cast.
3D Printing Material Best For Removal Method High-Temperature Wax Investment casting, metal molds Melting or dissolution Resin-based Photopolymer Plaster, ceramic molds Cleaning and solvent wash Thermoplastic Filament Multi-part molds, reusable patterns Mechanical separation The Casting and De-molding Process Once the pattern is prepared and coated, it is placed into a flask and surrounded by a mold box. Advantages Over Traditional Pattern Making Conventional pattern making relies heavily on skilled labor and can be time-consuming, especially for geometries with undercuts or complex internal structures.

Designers can iterate rapidly, modifying the digital file without the need to start the physical process from scratch. This mixture, usually composed of ceramic particles or gypsum suspended in water, must have the correct viscosity and solidification rate to capture fine details.
