Directionally solidified eutectic ceramics such as(Al)₂O₃/ZrO₂ are promising structural materials for applications in harsh environment with an ultrahigh temperature. In this work, through adopting assistant heating laser 3D printing,(Al)₂O₃/ZrO₂eutectic samples were manufactured with suppressing the formation of cracks. The dependence of the average rod spacing(λav) on the scanning rate(V) follows a relation with λav V0.5= 1 μm1....
