• The application of additive manufacturing method such as material extrusion (MEX) allows the successful fabrication of ceramic products, including multi-ceramic products. Promising materials in this research area are TiO and ZrO ceramics, which can be used in electrical and electronic engineering. The aim of this work is to investigate the possibility of fabricating TiO /ZrO multi-materials from ceramic pastes that can be used in the MEX. In this work, defects, chemical and phase composition, and microhardness were analyzed in multi-ceramic samples after sintering. Multi-ceramic TiO /ZrO samples after the sintering process without interlayer could not be fabricated due to a too large difference in shrinkage between TiO and ZrO . The samples with one and three interlayers also have defects, but they are less significant and can be fabricated. The average hardness for the TiO zone was 636.7 HV and for the ZrO zone was 1101 HV. In the TiO zone, only TiO phase in rutile is observed, while in the interlayer zones, in addition to rutile, ZrO and ZrTiO are also present, as is a small amount of Y O . In the zone ZrO , only the ZrO phase is observed. The chemical analysis revealed that the interlayers comprise sintered ZrO granules enveloped by TiO , ZrO , and ZrTiO .
