Abstract: The present disclosure relates to systems and methods useful for non-destructive evaluation (NDE) of molds and crucibles used in investment casting processes, including, without limitation, for producing aircraft engines, land-based turbine engines, and the like. According to one aspect, the present disclosure provides a system for non-destructive evaluation that includes a support, a 3D scanning device, and a computer component. According to another aspect, the present disclosure provides a method for non-destructive evaluation that includes the steps of: providing a system for non-destructive evaluation of a mold or crucible according to the present disclosure; 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.

Abstract: A method for assessment of operational performance of a 3D manufacturing apparatus is provided. Images are obtained, in real-time during a 3D polymer printing build process in which at least one structure is built by the 3D manufacturing apparatus, the images being of an area of a build platform on which the at least one structure is built. The obtained images are evaluating, and it is determined, based on the evaluating, whether an operational flaw with the 3D manufacturing apparatus has occurred. Operational flaws include errors in the operation of the 3D manufacturing apparatus and/or component thereof, as evidenced by, for instance, distortions or other errors in the structure(s) being built and/or materials being used.
