Abstract
A method is disclosed for additive manufacturing a three-dimensional object layer-by-layer including depositing a layer of material on a bed surface or a previously deposited layer of the object to form the object layer-by-layer; providing energy to the material after each layer is deposited with the energy being provided by an energy source that forms an energized beam directed at the material; altering a property of a gas surrounding the material and through which the energized beam extends to alter a property of the object constructed from the material; melting the material with the energized beam to form a melted pool of liquefied material; and allowing the material to solidify to bond the material to a previous layer of material of the object.
Claims10
A system for additively manufacturing a three-dimensional object layer-by-layer comprising:
- a bed surface;
- the object formed upon the bed surface and constructed from a material;
- a depositor configured to deposit the material layer-by-layer on the bed surface or a previously deposited layer of the object;
- an energy source configured to selectively direct an energized beam at the material to fuse a new layer of the material to a previously formed layer;
- a gas surrounding the material through which the energized beam extends;
- a control apparatus configured to adjust properties of the gas;
- and
- a melted pool of the material that has a depth that is modified by the control apparatus adjusting the properties of the gas to alter an amount of diffusion the energized beam experiences in order to change a property of the object constructed from the material.
