This paper presents a study on the support material compositions for selective vacuum manufacturing, a rapid prototyping technique that creates a physical prototype layer by layer with two conventional manufacturing processes: sand casting and material sintering. Experiments were conducted to identify the amount of cornstarch, reported to be an appropriate binder, mixed in the two types of support material: salt and silica sand. The experimental results recommended the different amount of cornstarch to the two types of the support material.
