ABSTRACT:
A process of making a casting includes the steps of designing a mold (1010), fabricating the layers (or laminations) of the mold (1020), stacking and assembling the laminations into a mold (1030), producing a casting (1060) and demolding the casting (1070). If necessary, a derived mold can be made (1040, 1050) prior to producing the casing (1060).
