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...
