Method for preparing controllable secondary orientation alloy sample through 3D printing wax mold

The invention relates to the field of single-crystal high-temperature alloys, in particular to a method for preparing a controllable secondary orientation alloy sample through a 3D printing wax mold. The method comprises the following steps: firstly, cutting out an axial tilt; 001gt, 001gt; , lt; 011gt, 011gt; the method comprises the following steps: preparing a cubic seed crystal with crystallographic orientation, preparing initial-section wax molds with different shapes by adopting a 3D printing technology, directionally assembling the seed crystal and the wax molds into a wax mold group with specific orientation, preparing a ceramic shell, and finally pouring a single-crystal high-temperature alloy sample capable of accurately controlling secondary orientation. Through directional assembly of the 3D printing wax mold and the seed crystal, manual errors caused by traditional manual assembly of the wax mold are reduced, and control of the seed crystal on secondary orientation of the single-crystal high-temp
