Abstract
A method for manufacturing a component, in particular a turbomachine component, in the form of a plurality of superposed layers of a material, includes a step of supplying the material into a feed nozzle and a step of projecting energy towards the feed nozzle to cause the material passing through the latter to melt. The method further includes a step of cooling the feed nozzle with a cooling element during the step of projecting energy.
Claims23
A method for manufacturing a component in a form of a plurality of superposed layers of a material on a manufacturing support, the method comprising the steps of:
- supplying the material into a feed nozzle;
- projecting energy towards the material to cause the material to melt on the manufacturing support;
- and
- cooling the feed nozzle by means of a cooling element during the energy projection step, wherein the cooling element is projected over an entire height of an external surface of feed nozzle to maintain geometric characteristics of feed nozzle, wherein the energy projection element is directed towards the material leaving the feed nozzle so as to melt the material before it is deposited on the manufacturing support.
An installation for carrying out a method for manufacturing a component in a form of a plurality of superposed layers of a material on a manufacturing support, the installation comprising a feed nozzle for the material for manufacturing the component and an element configured to project energy towards the material to melt the material on the manufacturing support, wherein at least one spray nozzle is configured to project a cooling element onto an external surface of feed nozzle and over an entire height of the feed nozzle to maintain a geometric characteristics of feed nozzle.
A method for manufacturing a component in a form of a plurality of superposed layers of a material on a manufacturing support, the method comprising the steps of:
- supplying the material into a feed nozzle;
- projecting energy towards the material to cause the material to melt on the manufacturing support;
- and
- cooling the feed nozzle by means of a cooling element during the energy projection step,
- wherein the cooling element is projected over an entire height of the feed nozzle to maintain geometric characteristics of feed nozzle,
- wherein several spray nozzles are arranged one above the other in a direction parallel to a height of the feed nozzle and the cooling element is projected along a direction perpendicular to the entire height of the feed nozzle,
- wherein the energy projection element is directed towards the material leaving the feed nozzle so as to melt the material before it is deposited on the manufacturing support.
