3D printing (3DP) leads to many defects and interfaces within printed parts. Failure during performance in the road-to-road and layer-by-layer processed parts appears at these interfaces and defects. Understanding the root cause of these limitations is key.
Only by mapping the sample via µ-beam SAX was it possible to determine the source of a peculiar defect and interface morphology. To the surprise of the scientists the alignment of nanoparticles is not uniform and not random within roads and layers of an epoxy carbon fiber reinforced composite and explains some of the achieved mechanical properties and microscopy results.
