The need for this improvement and the search for materials with better mechanical properties have given rise to a new range of materials.
PLA material is, along with ABS, one of the most widely used materials in additive manufacturing.
So, for this case study, the materials analyzed are presented in Table 1.
Only the Purifier material, which does not present visible particles as the other materials, presents a better behavior.

Composite materials, such as FRP and honeycomb structures, are used for crucial structures in aircraft.
In this study, a nondestructive shearography was applied to detect and characterize internal defects of composite materials for both CFRP laminates and honeycomb structure.
Therefore, some conventional nondestructive techniques, such as ultrasonics, acoustic emission, and eddy current, have been applied in evaluating delamination or debonding in composite materials.
