  • Additive manufacturing of zirconia ceramics: a state

    2020-7-1 · The debinding behavior depends on several factors such as resin composition, solid loading, and component geometry. To obtain pure zirconia ceramic brown bodies with inhibited defects, a two-step debinding process, which constitutes a vacuum debinding and a follow-up air debinding, was proposed by He et al. . The vacuum debinding could reduce the decomposition rate of organic …
