Abstract
A system is provided for additively manufacturing a part. This additive manufacturing system includes a base, a solidification device and a detection device. The base is adapted to support material; e.g., powder material. The solidification device is adapted to solidify at least a portion of the supported material to form at least a portion of the part. The detection device is adapted to detect emissions produced by the solidification of at least a portion of the material.
Claims19
A process for additively manufacturing a part, the process comprising:
- solidifying material with an energy beam to form at least a portion of the part;
- detecting emissions produced by the solidification of at least a portion of the material using a detection device;
- and
- moving the energy beam over the material, wherein the detection device detects the emissions within a region that follows behind a point where the energy beam is focused on the material;
- wherein the detection device does not detect emissions on the point where the energy beam is focused on the material.
A process for additively manufacturing a part, the process comprising:
- solidifying material with an energy beam to form at least a portion of the part;
- detecting emissions produced by the solidification of at least a portion of the material using a detection device;
- and
- moving the energy beam over the material, wherein the detection device detects the emissions within a region that follows behind a point where the energy beam is focused on the material;
- wherein the detecting of the emissions produced by the solidification comprises acquiring mass spectra along a path that is focused on the region that follows behind the point where the energy beam is focused on the material.
