Articles and structures prepared by three-dimensional printing method
The present invention relates to articles prepared 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.
1. An article comprising an auxiliary structure; and
one or more components produced by means of a three-dimensional printing method, whereby the auxiliary structure is constructed along with the one or more components and extending beyond a dimension of the one or more components;
wherein the auxiliary structure is connected directly to the one or more components; and
the auxiliary structure and the one or more components are formed from a same material;
wherein the same material includes a binder material.
2. The article of claim 1 , wherein the auxiliary structure forms a holder or a coupling device for handling the component(s) after removing the auxiliary structure and the component(s) from a surrounding material.
3. The article of claim 1 , wherein the auxiliary structure enables an automated handling of the components after removing the auxiliary structure and the component(s) from a surrounding material.
4. The article of claim 1 , wherein all constructed components are connected to the auxiliary structure.
5. The article of claim 1 , wherein the one or more components includes a first component and a second component and the auxiliary structure is connected directly to the first and second components.
6. The article of claim 1 , wherein the auxiliary structure largely surrounds one or more of the components.
7. The article of claim 1 , wherein the article includes a predetermined break points formed at junctions between each of the components and the auxiliary structure.
8. The article of claim 1 , wherein the auxiliary structure is connected to a first component at a first predetermined break point, wherein the first predetermined break point has a reduced amount of the binder.
9. An article comprising an auxiliary structure; and
multiple components produced by means of a three-dimensional printing method, whereby the auxiliary structure is constructed along with the components and extending beyond a dimension of the components;
wherein the auxiliary structure and the components are formed from a same material;
wherein the auxiliary structure is directly connected to two or more of the multiple components; and
the article includes multiple layers of components.
10. The article of claim 9 , wherein the auxiliary structure and the multiple components include a material deposited in layers and connected selectively by a further material or by applying energy; and the multiple components have a structure capable of being infiltrated by a fluid infiltration medium.
11. The article of claim 10 , wherein the auxiliary structure or a different auxiliary structure is directly connected to each of the multiple components.
12. The article of claim 9 , wherein the article includes a separate auxiliary structure on each layer of components.
13. An article comprising an auxiliary structure; and
multiple components produced by means of a three-dimensional printing method, whereby the auxiliary structure is constructed along with the components and extending beyond a dimension of the one or more components;
wherein the auxiliary structure is connected directly to one or more of the multiple components; and
the auxiliary structure and the multiple components are formed from a same material;
wherein the article includes a loose material between two of the two or more of the multiple components and/or between adjacent layers of the multiple components.
14. The article of claim 13 , wherein the multiple components includes a first component and a second component, the auxiliary structure and the first and second components include the same material deposited in layers and connected selectively by a further material or by applying energy; and the first and second components have a structure capable of being infiltrated by a fluid infiltration medium.
15. The article of claim 14 , wherein the auxiliary structure is connected to the first component at a first predetermined break point and is connected to the second component at a second predetermined break point.
