Stratasys FDM Parts as Masters for Sand Casting

For sand casting, the most common metals are iron, steel, bronze, brass and aluminum. With these alloys, sand casting can produce small parts that weigh less than one pound or large parts that weight several tons. The process is used to make medium to large parts such as valve bodies, plumbing fixtures, locomotive components and construction machinery. Its versatility also allows sand casting to produce small parts such as buckles, handles, knobs and hinges. It is a cost effective and efficient process for small lot production, and yet, when using automated equipment, it is an effective manufacturing process for high-volume production.

This process guide describes the application of Fused Deposition Modeling (FDM®) to automated (flaskless) casting with green sand. However, the information provided is also applicable to flask casting and dry sand.
