Additive manufacturing blank of honeycomb component and additive manufacturing method

The invention discloses an additive manufacturing blank of a honeycomb-shaped component and an additive manufacturing method, belongs to the technical field of additive manufacturing, and aims at solving the problems that in the prior art, after the honeycomb-shaped component is formed through additive manufacturing, the shape of an internal structure is difficult to change again, and the forming size is limited by equipment. The blank comprises a blank main body and a clamping part, a preset vacancy is formed in the blank main body, the preset vacancy is in a hexagon shape, and holes in the honeycomb-shaped component are in a regular hexagon shape; in the drawing direction, the width of the preset vacancy is smaller than that of the hole in the honeycomb-shaped component; and in the direction perpendicular to the drawing direction, the width of the preset vacancy is larger than that of the hole in the honeycomb-shaped component. The method comprises the steps that a blank is manufactured in an additive manuf
