In this work, a slurry-based laser sintering process is investigated. Laser sintering allows
for a broad palette of materials to be used. Since the binder content is only about 16 vol% with
respect to the ceramic powder load, the debinding process is faster and less susceptible to crack
formation and part warping compared to lithography-based manufacturing. The alumina slurry,
used as a starting material for laser sintering, was optimized by adjusting the dispersant content to
reach a minimum viscosity. After debinding and furnace sintering, multi-layer alumina parts with
densities up to 97% were obtained.
