Module for supplying additive manufacturing powder allowing drying of the powder

A supply module for supplying powder for additive manufacturing, the supply module comprising:

• a main hopper for storing additive manufacturing powder, the main hopper being configured to be connected to a manufacturing module configured to additively manufacture an object from the powder located in the main hopper;
• an inlet of the supply module, the inlet being configured to be connected to the manufacturing module and to receive powder located in the manufacturing module;
• a glovebox configured to receive a container, the glovebox being configured to be closed in a sealed manner;
• a provisioning circuit configured to transfer powder located in the glovebox to the main hopper;
• and
• a circulation system configured to set powder in motion according to a circulation loop that is closed and that circulates the powder, the circulation system comprising:
• a suction system that is remote from the main hopper, the suction system being configured to evacuate gas present in the circulation loop, the circulation loop passing through the main hopper and the suction system;
• a reservoir located below the main hopper, the reservoir comprising an outlet, the outlet being configured to be connected to a manufacturing duct, the manufacturing duct connecting the outlet of the reservoir and the manufacturing module;
• and
• a return circuit configured to redirect additive manufacturing powder located in the reservoir toward the inlet of the supply module, the return circuit connecting the outlet of the reservoir directly with the inlet of the supply module,
• wherein the circulation loop passes through the reservoir and the inlet of the supply module, and
• wherein the return circuit is different from the manufacturing duct.
