Method for producing three-dimensional components
First Claim
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.

Abstract
The present invention relates to a method for producing three-dimensional components, using a three-dimensional printing method, an auxiliary structure being additionally formed beyond an extension of the one or more components during the construction of components. The invention also relates to an auxiliary structure for components produced by means of three-dimensional printing methods, the auxiliary structure being constructed along with the component and extending beyond a dimension of the one or more components.
