Abstract
A method for analyzing a surface quality of a laminate part including the steps of creating a planned dimensioned representation of a laminate part desired to be built which includes a first surface having a first topography; placing fibers into locations for the laminate part desired to be built; and curing a resin associated with the placed fibers fabricating an as-built laminate part which includes a second surface having a second topography which corresponds to the first surface having the first topography. The method also includes aligning the first surface, the second surface and the locations of the fibers; determining a first elevation of a first point on the first surface and a second elevation of a second point on the second surface; and observing the first surface, the second surface and the locations of the fibers in alignment and the first elevation relative to the second elevation in analyzing the surface quality of the laminate part.
