Abstract (en)
A compound for manufacturing through rapid prototyping foundry moulds and cores which can be used for melting metallic alloys castings comprising a structural base component made of granular inert material and at least one binder suitable to increase the mechanical strength of said structural base component in respect to the hydrostatic pressure of the molten metallic alloy. In particular, the compound comprises at least one hygroscopic component suitable to at least partly absorb the humidity present in said structural base component, at least one reactant suitable to react with the oxygen present into the mould upon contact with the molten metallic alloy in order to trigger a combustion and at least one catalyst suitable to reduce the starting time of the combustion of said at least one reactant and increase the propagation rate of the combustion.
