WIPO Patent Application WO/2013/178825
Kind Code:
A3
Abstract:
The invention concerns, in particular, a machine (1) for additive manufacturing by sintering or melting powder (2) using an energy beam (3) acting on a layer of powder (23) in a work area (4), said machine comprising a layering device for layering said powder, said device comprising: - storage means (5) for storing the powder, - distribution means (6) for distributing the powder capable of traversing the work area in order to distribute the powder in a layer (23) having a final thickness (24) suitable for additive manufacturing, - supply means (7) capable of transferring the powder from the storage means (5) to the distribution means (6), - dosing means (8) capable of controlling the quantity of powder transferred from the storage means (5) to the distribution means (6), said machine being characterised in that: - the storage means (5) are placed higher than the work area (4), - the supply means (7) use gravity, - the supply means (7) and the dosing means (8) are movable with the distribution means (6), - the machine comprises two separate work areas (41, 42), the machine comprises two separate work plates (601, 602) that can be moved independent of each other, - each of the two separate work plates (601, 602) is associated with only one of the two separate work areas and - the layering device is shared by the two work areas.
