Schematic representation of the first five layers of scaffolds with a 0/90 orientation (top), 0/60/120 orientation (middle), and 0/45/90/135 orientation (bottom). All five layers are overlaid on top of one another in the right-hand column for each of the three different orientations—these represent top-down views of the scaffolds. For 0/90 and 0/60/120 scaffolds, the filaments on different layers all cross through the same points. For the 0/45/90/135 scaffold, filaments on different layers do not pass through the same points, which may result in a weaker structure
