Abstract

An applicator repair system for an additive manufacturing (AM) system, and an AM system including the same are disclosed. The applicator repair system includes a repair device including a repair element configured to repair a damaged applicator element on an applicator of an AM system. The damaged applicator element is configured to distribute a layer of raw material on a build platform of the AM system. The repair device is positioned within a processing chamber of the AM system. A damaged applicator controller may be provided that is configured to cause repair of the damaged active applicator in response to the damaged applicator being identified as damaged.

First claim

What is claimed is:

1. An applicator repair system for an additive manufacturing (AM) system, the applicator repair system comprising:
a repair device including a repair element configured to replace or repair a damaged applicator element on an applicator, the applicator positioned relative to a build platform of the AM system to apply a layer of raw material on the build platform,
wherein the repair device is positioned within a processing chamber of the AM system, the processing chamber of the AM system including:
an active applicator area in which an active applicator is movable relative to the build platform to apply the layer of raw material on the build platform from a raw material source;
a repair area located inside the processing chamber, and wherein the damaged applicator element and the repair device are located within the repair area; and
a partition in the processing chamber separating the repair area from the active applicator area, wherein the partition includes a separating wall separating the repair area and the active applicator area.

2. The system of claim 1 , further comprising a damaged applicator controller configured to cause replacement or repair of the damaged applicator element in response to the active applicator being identified as damaged.

3. The system of claim 2 , further comprising a damaged applicator identifier configured to identify whether the active applicator is damaged.

4. The system of claim 2 , further comprising a linear transport system under control of the damaged applicator controller for positioning the damaged applicator element relative to the build platform of the AM system and the repair device.

5. The system of claim 1 , wherein the repair device replaces or repairs the damaged applicator element by removing a damaged portion from the damaged applicator element.

6. The system of claim 5 , further comprising a material removal system configured to remove the damaged portion from the processing chamber during or after replacement or repair of the damaged applicator element.

7. The system of claim 5 , wherein the repair device supplies a size of the damaged portion to a control system of the AM system for adjusting of the AM system to accommodate a removal of the damaged portion.

8. The system of claim 1 , wherein the damage applicator element includes a flexible material, and the repair element includes a cutting device configured to remove a damaged portion of the flexible material from the damaged applicator element.

9. The system of claim 8 , wherein the applicator carries a supply of the flexible material, and the repair device further includes a flexible material positioner for obtaining a replacement portion for the damaged portion of the flexible material from the supply of the flexible material.

10. The system of claim 1 , wherein the damaged applicator element includes a metal material, and the repair element includes a grinding device configured to remove a damaged portion of the metal material from the damaged applicator element.

11. The system of claim 1 , wherein the damaged applicator element includes a moldable material, and the repair element includes a molding device configured to reshape a damaged portion of the moldable material of the damaged applicator element.
