Abstract
An additive manufacturing system with a build chamber has a halide vessel that generates a halide gas and a dissociation chamber with a filament. Metal condensate is contacted with the halide gas to form a gaseous metal halide compound. The gaseous metal halide compound is decomposed to deposit metal on the filament. In an example, titanium reacts with gaseous iodine to form gaseous titanium tetraiodide.
Claims22
An additive manufacturing system comprising:
- a build chamber;
- a laser source configured to direct a laser beam into the build chamber thereby forming metal condensate in the build chamber;
- a halide vessel connected to the build chamber, wherein the halide vessel includes a halide gas source;
- and
- a dissociation chamber connected to the halide vessel, wherein the dissociation chamber includes a filament.
