Abstract
Official abstract text for this publication.
A process for the additive manufacture of a part within a machine, the machine including a working surface, a device for spreading the powder layer along at least one longitudinal horizontal direction, at least one injector of powder over the working surface, the injector being movable with respect to the working surface along at least one transverse horizontal direction, and a system for regulating the amount of powder dispensed by the injector, the process including the following stages: moving the injector along a trajectory comprising at least one component parallel to the transverse horizontal direction; and regulating the amount of powder dispensed by the injector at any point of the trajectory of the injector.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for the additive manufacture of a part by partial or complete selective melting of a powder within a machine, the machine comprising: (a) a working surface configured to receive a powder layer, (b) a spreading device for spreading the powder layer along at least one longitudinal horizontal direction over the working surface, (c) at least one injector for directly injecting powder over the working surface, the injector being movable with respect to the working surface along at least one transverse horizontal direction, and (d) a system for regulating an amount of powder dispensed by the injector, the process comprising the following steps: moving the injector along a trajectory comprising at least one component parallel to the transverse horizontal direction in order to dispense powder along at least one line on the working surface; and regulating the amount of powder dispensed by the injector at any point of the trajectory of the injector such that a height of powder of the line of dispensed powder is greater close to each transverse end of the line than the height of powder located substantially at the transverse middle of the line. 2. The process according to claim 1 , wherein the injector is movable with respect to the working surface along the longitudinal direction. 3. The process according to claim 2 , wherein the injector is integrally attached, along the longitudinal direction, to the spreading device. 4. The process according to claim 1 , wherein the injector is mounted in movable fashion in the machine. 5. The process according to claim 1 , wherein the injector is movable with respect to the working surface along a vertical direction, and wherein the regulating system regulates the vertical position of the injector with respect to the working surface. 6. The process according to claim 1 , wherein the regulating step is carried out as a function of a geometry of the part to be manufactured. 7. The process according to claim 1 , wherein the regulating step is carried out as a function of dimensions of the part to be manufactured. 8. The process according to claim 1 , wherein the regulating step is carried out as a function of a position of the part to be manufactured on the working surface. 9. The process according to claim 1 , wherein the regulating step is carried out as a function of a material of the region of the part to be manufactured on the working surface.
