Figure 1. Scanning electron microscope images of computer-aided design/computer-aided manufacturing polymer ceramics before cutting. (A) Enamic (×2,500) showed a homogeneous distribution of the ceramic phase (white arrow) and the polymer phase (red arrow); (B) With higher magnification (×5,000), the ceramic particles with sharp edges (white arrow) and amorphous polymer phases (red arrow) were displayed; (C) LAVA Ultimate (×2,500) showed distributed roughness on the surface; (D) With higher magnification (×5,000), organic fibers (white arrow) embedded in the polymer matrix were observed.
