Abstract

Official abstract text for this publication.

An additive manufacturing system for printing an article including a build plate having a build surface between an inner radius and an outer radius that may receive powder particles and a recoating assembly that may distribute the powder particles onto the build surface to form a build layer of the article. The recoating assembly includes a support jig having a first end, a second end, and a support wall extending between the first and second ends and a recoater blade coupled to the second end and extending along at least a portion of a length of the support wall. A shape of the recoater blade is such that, when the recoater blade is positioned against the build surface, an angle between the recoater blade and a tangent at each radii of the build plate is substantially constant.

First claim

Opening claim text (preview).

The invention claimed is: 1. A recoating assembly for use in a rotary additive manufacturing system, comprising: a support jig comprising a first end, a second end, and a support wall extending between the first and second ends; and a curved recoater blade configured to distribute powder particles onto an annular build plate of the rotary additive manufacturing system while the annular build plate is rotating about a platform axis to form a build layer of an article to be printed, wherein the curved recoater blade is coupled to the second end and comprises a shape having a curvature orthogonal to the platform axis. 2. The recoating assembly of claim 1 , wherein the curvature forms an angle relative to a tangent at each radii of the annular build plate that is constant. 3. The recoating assembly of claim 1 , wherein the curvature has a pitch that is between approximately 10 degrees and 75 degrees. 4. The recoating assembly of claim 1 , wherein the curved recoater blade comprises a wall that forms the shape of the curved recoater blade, the wall having a first face and a second face opposite the first face, and wherein the first face is curved and configured to engage the powder particles to distribute the powder particles across the build surface. 5. The recoating assembly of claim 1 , wherein the support wall comprises one or more openings, one or more protrusions, or both, configured to couple the recoating assembly to a support structure of the rotary additive manufacturing system. 6. The recoating assembly of claim 1 , wherein the curvature is uniform along a length of the curved recoater blade. 7. The recoating assembly of claim 1 , wherein the curved recoater blade is flexible. 8. The recoating assembly of claim 1 , wherein the curved recoater blade is rigid.
