Inherently, additive manufacturing printed parts have faults between layers perpendicular to the direction of printing, both in the plane parallel to the build plate and in the z direction (out of the build plate). For most parts, these “built-in” faults from the manufacturing process act as limiting conditions for the part's mechanical strength. While perpendicular to printing is typically the weakest due to layer adhesion faults, parallel to printing is typically the strongest due to cohesive material and fiber orientation. Fiber orientation can be measured through various methods, with the two explored being X-Ray Microscopy (XRM) for 3D analysis, and …
