Embodiment Construction

[0028] figure 1 A known apparatus for manufacturing metal parts by selective melting of powder is shown. It comprises: a tank 1 comprising metal powder 2 and having a bottom 3 movable in the direction of vertical translation by means of a rod 4 of an actuator; and an adjacent container 5 in which, Its bottom is formed by a movable plate 6 fastened to a movable support 7 which is likewise movable in the direction of vertical translation by means of a rod 8 of an actuator.

[0029] The device also has a wiper 9 for moving the powder from the tank 1 to the container 5 by moving along the horizontal plane A, and a member 10 for generating a laser beam or an electron beam, which is connected to guide and move the The device 11 of the bundle 12 is connected.

[0030] The steps to make metal parts with the help of this device are as follows:

[0031] First, the bottom 3 of the tank 1 is moved upwards so that a quantity of powder 2 lies on the horizontal plane A. The wiper 9 then ...

Abstract

The invention relates to a device for the manufacture of components by selectively melting powder, comprising: a container, the bottom of which is formed by a movable plate (6); for bringing powder into said container and means for generating and moving a laser or electron beam designed to cause selective melting of powder in a container. The movable plate (6) is provided with means (24) for stretching in at least one direction (X) parallel to its plane.

Description

technical field [0001] The invention relates to a device for the manufacture of components by selective melting of powders with the aid of a laser beam or an electron beam. Background technique [0002] Such devices enable the manufacture of components with the aid of known methods by means of direct metal laser sintering or electron beam melting. [0003] The method involves making a part by melting successive layers of powder by means of a laser beam or an electron beam, which is controlled by a data processor system which has recorded the in the three-dimensional coordinates of the point. In a practical manner, the container has a bottom formed by a plate movable in the direction of vertical translation, with a first layer of powder positioned on its bottom with the help of a wiper. The layer then has a bottom surface corresponding to the top surface of the plate and a top surface onto which the laser or electron beam is directed and moves. The energy delivered by the ...
