Methods and systems for additively manufacturing a unitary ceramic part and repairing damaged ceramic parts including additively manufacturing a first ceramic green body having a joint surface and a second ceramic green body having a joint surface, wherein the joint surfaces are configured to be interfaced. The first ceramic green body and the second ceramic green body are sintered to form the unitary part. Additional ceramic green bodies may be connected and sintered to form the unitary part. The ceramic green bodies may have defects or may be damaged. A ceramic sheet may be manufactured and applied to the ceramic green bodies to repair the defects or damage. The ceramic sheet may be sintered with the ceramic green bodies to form the unitary part.

A chamber body includes a ceramic weldment having an upper wall, a sidewall, and a lower wall. The upper wall is coupled to the sidewall by a sidewall-to-upper wall weld and includes an upper wall rib segment coupled to an upper wall plate by an upper wall rib segment weld. The sidewall is coupled to the lower wall by a sidewall-to-lower wall weld. The lower wall has a lower wall plate portion and a lower wall rib portion extending therefrom both formed from a singular ceramic workpiece using a subtractive manufacturing technique, the lower wall plate portion thereby defining a lower wall unwelded ribbed region including a plurality of lower wall rib segments defined by the lower wall rib portion of the lower wall. Chamber arrangements, semiconductor processing systems, and methods of making ceramic weldments for chamber bodies in chamber arrangement and semiconductor processing systems are also described.
