Embodiment Construction

[0033] Such as figure 1 As shown, the present invention relates to an additive manufacturing facility that includes a plurality of additive manufacturing machines M1, M2, M3, M4, and the plurality of additive manufacturing machines M1, M2, M3, M4 are installed in the facility The airtight room 10 inside.

[0034] The sealed chamber 10 refers to a sealed chamber that prevents the air in the chamber from circulating to the outside of the chamber.

[0035] Such as Image 6 It can be seen that each machine M1, M2, M3, M4 includes a manufacturing cavity 12 and manufactures parts in the cavity 12 in an automatic and closed manner. Manufacturing is called airtight because the manufacturing chamber 12 can be closed in a sealed manner to prevent the air inside the manufacturing chamber 12 from circulating to the outside of the chamber (ie, the closed room 10 of the facility).

[0036] Advantageously, each machine M1, M2, M3, M4 may include multiple (preferably two) working areas within its m...

Abstract

The invention relates to an automated and confined additive manufacturing facility. The facility comprises a confinement chamber (10) inside which a plurality of additive manufacturing machines (M1, M2, M3, M4) are installed, each machine (M1, M2, M3, M4) comprising a manufacturing chamber (12), the facility further comprising, inside the confinement chamber (10), a supply device (18) and a supplycircuit (20) for supplying an additive manufacturing powder to the different machines (M1, M2, M3, M4) in the facility, a conveying device (42) for conveying additive manufacturing container / tray assemblies (C) and comprising at least one conveying chamber (44) circulating between the different machines (M1, M2, M3, M4), and a cleaning device (50) comprising at least one cleaning chamber (52) forcleaning automatically and in a confined manner the additive manufacturing trays in the cleaning chamber (52).

Description

Technical field [0001] The present invention relates to the field of powder-based additive manufacturing by sintering or melting powder particles using an energy beam with electromagnetic radiation (such as a laser beam) and / or a particle beam (such as an electron beam). [0002] More specifically, the present invention relates to the containment of an additive manufacturing facility including a plurality of additive manufacturing machines and the closed transportation of additive manufacturing pallets within the facility. Background technique [0003] During the additive manufacturing method in the manufacturing chamber of the additive manufacturing machine, a first powder layer is deposited on the additive manufacturing tray, which is slidably mounted in the manufacturing sleeve, Keep in place in the manufacturing cavity. Then, the first powder layer is solidified in a predetermined pattern using one of the aforementioned energy beams. Then, the manufacturing tray is lowered wi...
