Systems for non-destructive evaluation (NDE) of molds and crucibles used in investment casting processes include a support, a 3D scanning device, and a computer component. Methods for non-destructive evaluation include providing a system for non-destructive evaluation of a mold or crucible; securing a mold or crucible to the support of the system; and operating the 3D scanning device of the system in conjunction with the computer component in order to create a 3D structure difference map that indicates whether the mold or crucible falls within or outside a desired structural integrity parameter range.
