Lithography-based Ceramics Manufacturing Technologies

In this work, surrogate powders were prepared with lithography-based ceramic printing. Lanthanum oxide, a powder from Oak Ridge National Laboratory (ORNL), was prepared by milling, characterizing, and printing of coupon samples. The printing resulted in net-shaped green parts. Alumina, a more developed powder, was also printed and characterized at ORNL, and these parts were surrogate geometries larger than coupons that were sintered to net shape within 0.3% of the desired geometry.
