Embodiment Construction

[0046] figure 1 The interior of a machine 1 for the additive manufacturing of components starting from powder material by complete or partial selective melting is shown schematically in detail. The material used can be, for example, metal or plastic. More specifically, figure 1 The working plane 2 inside the machine 1 corresponding to the cavity bottom is shown in . Preferably, the atmosphere within the chamber is inert with respect to the materials used.

[0047] For purposes of clarity and brevity, the working plane 2 is considered here to be horizontal. A longitudinal horizontal axis X and a transverse horizontal axis Y are then defined, parallel to the working surface 2 and orthogonal to each other. The adjective "longitudinal" and its alternatives hereinafter mean any direction parallel to the longitudinal axis X; likewise the adjective "transverse" and its alternatives hereinafter mean any direction parallel to the transverse axis Y.

[0048] More specifically, the ...

Abstract

The invention relates to a machine (1) for the additive manufacturing of workpieces by selectively melting all or part of a powder, said machine comprising: a horizontal working plane (2); at least one spreading device (6); at least one system (7) for distributing powder on said working plane (2), said system (7) comprising at least one tray (8) for holding powder and at least one powder injector (9); the tray (8) is movable in translation relative to said working plane (2), and the injector (9) is arranged above the tray (8) so as to dispense powder to the on the pallet (8) that moves between positions.

Description

technical field [0001] The present invention relates to the field of additive manufacturing machines, also known as 3D printers. More specifically, the invention relates to spraying powders in such machines. Background technique [0002] According to known techniques, the parts are produced by "3D" printing from powder. Parts are pre-cut into slices using the CAO tool. The powder is then spread on the working surface in successive layers, with each layer going through stages of melting and solidification before being covered by the next. For this purpose, the supply of energy, for example by means of a laser beam, enables the formation of solid bodies corresponding to slices of the part to be produced in the powder layer. The part to be manufactured is usually supported by a plate which moves within the manufacturing chamber as the part slice melts and solidifies, enabling the next powder layer to be formed. The plate thus defines the target surface, ie the surface on wh...
