A high-speed additive manufacturing apparatus includes a main body, a sintering module, a product carrying member, a raw material carrying member, and a raw material wiper. The main body includes a printing tank and a raw material tank adjacent to the printing tank. The sintering module is arranged on the main body. The sintering module includes a plurality of sintering light source assemblies. Each of the sintered light source assemblies has a light beam emitting end. The light beam emitting end emits a sintering light beam. The light beam emitting ends of the sintering light source assemblies are arranged in a plurality of rows. Each light beam emitting end in one row is unaligned with the light beam emitting end in adjacent rows along a direction in which the light beam emitting end moves.

A laser-solid-forming manufacturing device includes a laser emitter, a magnetic field generator, and a forming platform. The laser emitter emits a laser beam which acts on a feedstock to form a molten pool. The magnetic field generator includes a spiral copper coil, a first electrode and a second electrode. The spiral copper coil is formed by spirally winding a copper tube. The first and second electrodes are arranged at respective ends of the copper tube and are used for loading a voltage to generate a magnetic field in the spiral copper coil. At any time, the spiral copper coil sleeves an action point of the laser beam and the feedstock. A corresponding laser-solid-forming manufacturing method is also presented.

A three-dimensional shaping device includes: a discharge unit having a nozzle and configured to discharge a material toward a stage; a cleaning mechanism configured to clean the nozzle; and a moving unit configured to move the discharge unit and the cleaning mechanism relative to the stage. The moving unit is configured to move the cleaning mechanism relative to the stage in conjunction with the movement of the discharge unit relative to the stage.

Apparatus for additively manufacturing three-dimensional objects formed by irradiation and consolidation of layers of build material. The apparatus may include at least one build plane; at least one build material application device being adapted to apply an amount of build material in the at least one build plane, the at least one build material application device comprising at least one build material application element being moveably supported in a first motion path in which the at least one build material application element is moveable or moved across the at least one build plane, wherein the at least one build material application element is transferrable in a first orientation in which the at least one build material application element is operable to apply an amount of build material in the at least one build plane and in a second orientation in which the at least one build material application element is not operable to apply an amount of build material in the at least one build plane.

The devices, systems, and methods of the present disclosure are directed to powder spreading and binder distribution techniques for consistent and rapid layer-by-layer fabrication of three-dimensional objects formed through binder jetting. For example, a powder may be spread to form a layer along a volume defined by a powder box, a binder may be deposited along the layer to form a layer of a three-dimensional object, and the direction of spreading the layer and depositing the binder may be in a first direction and in a second direction, different from the first direction, thus facilitating rapid formation of the three-dimensional object with each passage of the print carriage over the volume. Powder delivery, powder spreading, thermal energy delivery, and combinations thereof, may facilitate consistently achieving quality standards as the rate of fabrication of the three-dimensional object is increased.

A compactor is disclosed for use with an additive manufacturing print head. The compactor may include a housing connectable to the additive manufacturing print head. The compactor may also include a compacting wheel, and at least one spring disposed in the housing and configured to exert an axial force on the compacting wheel. The compactor may further include a piston moveable to adjust a distance between the housing and the compacting wheel.

Disclosed embodiments relate to recoater systems for use with additive manufacturing systems. A recoater assembly may be used to deposit a material layer onto a build surface of an additive manufacturing system. In some instances, the recoater assembly may include a powder entrainment system that trails behind a recoater blade of the recoater assembly relative to a direction of motion of the recoater blade across a build surface of the additive manufacturing system. The powder entrainment system may generate a flow of fluid across a portion of the build surface behind the recoater blade that at least temporarily entrains powder above a threshold height from the build surface to mitigate, or prevent, the formation of defects on the build surface with heights greater than the threshold height.

Build receptacles for additive manufacturing apparatuses are disclosed. The build receptacle may comprise a housing comprising a sidewall at least partially enclosing a build chamber. A build platform may be positioned within the build chamber. A position of the build platform may be slidably adjustable within the build chamber in a vertical direction from a lower position to one of a plurality of upper positions and from the one of the plurality of upper positions to the lower position. The build receptacle may further comprise a plurality of heating elements disposed around the build chamber.
