Fig. 6

Micro OCT B-scans. The left views are cuts through the sample, perpendicular to the direction of printhead movement. The right panels show the same inclusions, but the view is rotated by \(90^\circ\). The light objects are the inclusions to be seen on the dark background of the matrix material. The horizontal white bars on the top of the images are the surfaces of the samples. As shown on the right side, the inclusions are wavy in the direction of the print head movement. The first layers of the print are shown at the top of the image. Starting with the flat matrix layer, the waviness increases as the multimaterial layer is increased. All images show RGD8530-DM inclusions in VeroClear matrix. The volume fractions are \(f_{inc} = 10\%\), \(f_{inc} = 30\%\) and \(f_{inc} = 45\%\) from top to bottom. The depth scale has been corrected from \(1.484\,\)mm optical distance to the geometric distance shown here
