Ceramic dental crowns composed of yttria-stabilized zirconia（YSZ）were fabricated by stereolithographic additive
manufacturing（STL-AM）. The YSZ composite appeared translucent on crown surfaces. In graphic modeling, installation structures
were designed to hold and mount the crown object with free surfaces. The nanoparticles were dispersed in acrylic resins to obtain
a paste-like consistency for STL processing. An ultraviolet laser beam was scanned over the evenly spread out paste to create
two-dimensional （2D）cross sections. Through layer stacking and interlayer bonding, three-dimensional （3D）components were
successfully shaped. The dimensional tolerances for the horizontal and vertical features were optimized by systematic modulation
of the irradiated power. The composite precursors were dewaxed and sintered in ambient air to create the filled ceramic crowns. The
dense ceramic microstructures were observed using scanning electron microscopy（SEM）. The linear shrinkages were measured and
incorporated into the model for structural design to realize high-dimensional accuracies.
