Then, press Control + J to combine the objects into a single mesh.

In Object Mode, select the head and the support.

Hover your pointer over the subdivision modifier, then hit Control + A to ensure it is applied. Note: Making an object “watertight” in Blender for 3D printing with these 4 steps The flaws are loose pieces, open edges, and other imperfections that might show up in a 3D virtual space.

This requires that the object have a continuous surface free of flaws. An object must be manifold, or “watertight,” in order to be ready for 3D printing.
