Abstract
A pulverant material supply system has an outer shell, an inner shell, and a plurality of openings to a passage within the inner shell to allow a reducing fluid into the pulverant material contained therein. The liner is made from a non-evaporable getter alloy.
Claims20
A pulverant material supply system comprising:
- an outer shell;
- an inner shell disposed within the outer shell and shaped to contain pulverant material, comprising a plurality of openings therein to allow for the passage of a fluid, and wherein the inner shell is formed from a non-evaporable getter alloy, and
- a fluid passage between the inner shell and the outer shell.
A method of conditioning a pulverant material for additive manufacturing, the method comprising:
- positioning a pulverant material within a conditioning system, the conditioning system including a liner made of a non-evaporable getter alloy;
- heating the liner an activation temperature;
- and
- passing an inert gas through the liner.
1 more element
An additive manufacturing system, comprising:
- a source of radiation;
- a reservoir of pulverant material;
- a liner adjacent to the reservoir, the liner having a passage in fluid communication with a plurality of bleed holes;
- a pulverant material supply system configured to provide conditioned pulverant material from the reservoir to a work stage, and
- an optical positioning system configured to direct radiation from the source of radiation towards the conditioned pulverant material at the work stage.
