In many respects, the process involved in these two investment casting methods is similar. In both cases, a sacrificial pattern is made. In lost wax casting, this is made from a tooled mould and in lost foam casting, it may be made from a mould or carved from a solid block of foam material. A … Read more
3D Printing: Prototype Mould Production
Green sand casting relies on the production of a pattern which is used to create a mould. The casting process itself is reasonably straight-forward but fabricating the patterns is often difficult and carried out by highly skilled patternmakers which is time-consuming and expensive. Prototyping of the cast component is required to ensure final dimensions are achieved and casting defects are eliminated.
NovaCast is at the forefront of the metal casting industry in employing 3D printing in the production of prototype patterns in its non-ferrous sand casting process. The technology has emerged as a significant additive manufacturing process in recent years, particularly in rapid prototyping and short-run production of complex geometric shapes.
NovaCast uses the Selective Laser Sintering (SLS) process, which integrates seamlessly with its 3D Modelling and Casting Simulation software to produce a loose pattern for prototyping of cast components. Employing the latest technology in this way allows NovaCast to reduce both costs and lead times.
