According to some configurations of the present disclosure, an alloy may include a composition that includes magnesium (Mg) that is approximately 5 to 12% by weight of the composition; manganese (Mn) that is approximately 0.1 to 2% by weight of the composition; and silicon (Si) that is approximately 0.3 to 3% by weight of the composition; and aluminum (Al) that is a balance of the composition. In one configuration, the composition may further include one or more of iron (Fe), titanium (Ti), zirconium (Zr), chromium (Cr), and/or yttrium (Y).

Aluminum alloys

Systems and methods of support structures in powder-bed fusion (PBF) are provided. Support structures can be formed of bound powder, which can be, for example, compacted powder, compacted and sintered powder, powder with a binding agent applied, etc. Support structures can be formed of non-powder support material, such as a foam. Support structures can be formed to include resonant structures that can be removed by applying a resonance frequency. Support structures can be formed to include structures configured to melt when electrical current is applied for easy removal.

Support structures in additive manufacturing

Systems and methods for rotational additive manufacturing are disclosed. An apparatus in accordance with an aspect of the present disclosure comprises a build floor, a depositor system configured to deposit a layer of powder onto the build floor, a motor system causing a rotational motion between the depositor system and the build floor, wherein the depositor system deposits the layer of powder during the rotational motion, a receptacle wall configured to contain the powder on the build floor, an energy beam source configured to apply an energy beam in an active area of the layer of powder to selectively fuse a portion of the powder in the active area to form a portion of a build piece and a gas flow system configured to provide a gas flow across the active area while the energy beam selectively fuses the portion of the layer of powder in the active area.

Rotational additive manufacturing systems and methods

Systems and methods of adapting the geometrical shape of a laser beam in laser-based powder-bed fusion (PBF) are provided. An apparatus for laser-based powder-bed fusion includes a depositor that deposits a plurality of layers of a powder material. The apparatus further includes a laser beam source that generates a laser beam having a variable beam geometry. A laser application component applies the laser beam in one of a plurality of beam geometries to fuse the powder material to construct a build piece.

Variable beam geometry laser-based powder bed fusion

Systems, apparatus, and method for forming a structure are disclosed. An apparatus for forming a structure may be configured to receive instructions for printing at least one portion of the structure. The instructions may be based on a data model of the structure. The apparatus for forming a structure may be configured to receive material and print the at least one portion of the structure based on the instructions. The printing may include spray forming the material to produce the at least one portion of the structure.
