Method for producing three-dimensional components
(57) 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.

Claims (14)

  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.
  2. A method for producing one or more three-dimensional components, using a three-dimensional printing method, wherein an auxiliary structure is additionally formed beyond an extension of the one or more components during the construction of components, and this auxiliary structure lies at least partially outside a projection area of the one 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 multiple layers of components are formed and a separate auxiliary structure is formed on each layer of components.
  3. A method for producing one or more three-dimensional components, using a three-dimensional printing method, wherein an auxiliary structure is additionally formed beyond an extension of the one or more components during the construction of components, and this auxiliary structure lies at least partially outside a projection area of the one 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 predetermined break points are formed at junctions between the component and auxiliary structure.
  4. A method for producing a plurality of three-dimensional components including first and second three-dimensional components comprising the steps of: i) printing the three-dimensional components on a build platform by a three-dimensional printing method, wherein the three-dimensional printing method includes repeatedly: a. providing a layer of particulate material, and b. selectively printing a binder on the particulate material; ii) forming an auxiliary structure by the three-dimensional printing method, wherein the auxiliary structure is formed beyond an extension of the plurality of components during the construction of components, wherein the auxiliary structure lies at least partially outside a projection area of the plurality of components projected onto the build platform and does not come into direct contact with the build platform, wherein the first and second components are connected to the auxiliary structure; and iii) separating the first and second components from the auxiliary structure.

Description

The present application claims priority from German Application No. DE 102007033434, filed on Jul. 18, 2007 and is the National Phase of PCT Application PCT/DE2009/001073, filed on Aug. 6, 2007, disclosure of which is hereby incorporated by reference herein.

The present invention relates to a method for producing three-dimensional components, using a three-dimensional printing method.

Methods for producing three-dimensional components have been known for some time.

For example, a method for producing three-dimensional objects from computer data is described in the European patent specification EP 0 431 924 B1. In this method, a particulate material is deposited in a thin layer onto a platform, and a binder material is selectively printed on the particulate material, using a print head. The particle area onto which the binder is printed sticks together and solidifies under the influence of the binder and, if necessary, an additional hardener. The platform is then lowered by a distance of one layer thickness into a build cylinder and provided with a new layer of particulate material, which is also printed as described above. These steps are repeated until a certain, desired height of the object is achieved. A three-dimensional object is thereby produced from the printed and solidified areas.

After it is completed, this object produced from solidified particulate material is embedded in loose particulate material and is subsequently removed therefrom. This is done, for example, using an extractor. This leaves the desired objects, from which the remaining power is removed, for example by brushing.
