Casting method using a synthetic model produced by stereolithography

摘要

A synthetic model (28) of a component (10) is created from a 3-D numerical model (26) thereof. A core is then cast inside the synthetic model (28). The synthetic model (28) may then be removed from the cast core, and then the cast core is used for casting an authentic component (10) therearound. The core is removed from inside the authentic component (10), which authentic component precisely matches the original synthetic model (28) therefor.
