1. A method for producing two or more three-dimensional components, using a three-dimensional printing method, wherein an auxiliary structure is additionally formed beyond an extension of the two or more components during the construction of components, and this auxiliary structure lies at least partially outside a projection area of the two or more components projected onto a build platform and does not come into direct contact with the build platform, wherein the three-dimensional printing method includes repeatedly, i) depositing a layer of particulate material;

  • and ii) selectively printing a binder material on the particulate material, until a desired height is achieved;

    wherein the auxiliary structure is additionally constructed in such a way that at least two simultaneously constructed components are connected to each other.
