Embodiment Construction

[0042] figure 1 A powder-based additive manufacturing device 10 according to a first embodiment of the invention is shown.

[0043] Apparatus 10 includes a substantially planar platen 12 on which layering device 14 is displaceable along a path connecting a starting region A of platen 12 and an ending region B of platen 12 (for clarity, layering means 14 can be guided The mechanism for device displacement is not shown in the figure). More specifically, in the embodiment shown in the figures, the layering device 14 is displaced by performing a translation along the axis X.

[0044] In the route of the path connecting the start area A and the end area B, the layer forming device passes through the powder deposition area P (also called the working area) of the press plate 12, which is located between the end area B and the start area. A, and is used to accommodate a certain dose of powder delivered by the layering device 14. This dose of powder is then used for melting or sinte...

Abstract

The invention relates to a powder-based additive manufacturing unit (10) comprising a powder layering device (14) capable of following a path connecting a starting area (A) and an ending area (B) shift. The layer forming device (14) includes a powder deposition mechanism (18), and the powder deposition mechanism (18) is used to deposit the powder in the powder deposition area between the start area (A) and the end area (B) (D). The unit comprises a cleaning device (40) located in the path of the layering device (14). The cleaning device (40) comprises air blowing means (42) designed to blow a flow of air onto at least one surface of the powder deposition mechanism (18).

Description

technical field [0001] The invention relates to the field of powder-based additive manufacturing of components. [0002] More specifically, the invention relates to powder-based additive manufacturing equipment for components and layering devices for such equipment. Background technique [0003] Powder-based additive manufacturing equipment for components generally comprises a powder layering device displaceable along a path connecting a starting area and an ending area, the powder layering device being provided with a powder deposition mechanism, the powder The deposition mechanism is capable of depositing powder on a powder deposition area located between the start area and the end area. These powder deposition mechanisms include, for example, hoppers, compartments with removable trap doors, or even metering cylinders provided with cavities containing doses of powder. [0004] After being deposited on its deposition area, the powder is most often arranged in layer form u...
