Abstract: Additive manufacturing systems and associated methods are disclosed herein. In some embodiments, the additive manufacturing includes a build chamber that has a central portion and a peripheral portion, a support platform positioned in the central portion and a recoater arm movable in a lateral direction over the support platform. While moving, the recoater arm spreads a powder over the central portion during a build. The additive manufacturing system also includes a powder recycling system positioned to redirect excess amounts of the powder during the build. For example, the powder recycling system can include a powder receptacle positioned the second region of the peripheral portion and a recycling element positioned at least partially in the powder receptacle. The recycling element is movable between a first position abutting an overflow space in the powder receptacle to receive the excess powder and a second position closer to the central portion.

Abstract: Additive manufacturing systems and associated methods are disclosed herein. In some embodiments, the additive manufacturing system includes a build chamber that has an active build region, a support platform positioned in the active build region and movable in an upward direction, and a recoater arm positioned in the build chamber and movable in a first lateral direction above the active build region. The recoater arm can spread a powder over the active build region during a build process using first and second blades. The recoater arm can also include at least one orifice component positioned between the first and second blades to block a flow of the powder while the at least one orifice component is stationary and a vibrational component operably coupled to the at least one orifice component. The additive manufacturing system can also include a controller operably coupled to the vibrational component, to control operation of the vibrational component.

Abstract: Additive manufacturing systems and associated methods are disclosed herein. In some embodiments, the additive manufacturing system includes a build chamber that has active build region, a support platform positioned in the active build region, a recoater arm, and a chamber-purging system. The recoater arm is movable in a lateral direction along a travel path above the active build region to spread a powder over the active build region. The chamber-purging system includes extendable input and return channels that are movable between a first position outside the travel path and a second position at least partially within the travel path.

Abstract: Systems and methods for controlling additive manufacturing processes are disclosed. The systems can include multiple laser directors, soot-removal devices, magnetic chucks, replenishable powder distribution blades, automated powder level detectors, and/or overall process automation techniques.
