1. A method of building up a physical object by additive manufacturing, the method comprising the steps of:
building up the object and at least one support structure layer by layer along a build axis, wherein the support structure supports the object relative to a build platform,
during building up of the object and the at least one support structure, providing a connection between the support structure and the object by a plurality of layers each of which being a common layer of the object and the support structure, and
providing the connection between the support structure and the object with at least one void that is filled with non-hardened light hardenable material.
