Abstract: A wash station (10) for cleaning a downward facing printer head (12) in metal-binder jetting is proposed. The wash station (10) comprises: a frame (16); a nozzle (20) for projecting a cleaning liquid in an upward direction; a nozzle support (18) supporting the nozzle (20), wherein the nozzle support (18) is movable relative to the frame (16). The wash station (10) further comprises: an actuator (22) configured to position the nozzle support (18) in a first position and in a second position relative to the frame (16), wherein the second position is above the first position. The wash station (10) further comprises: a lid (24) configured to transition between a closed position and a first open position at a change in position of the nozzle support (18) between the first position and the second position of the nozzle support (18), wherein the lid (24) is positioned above the nozzle (20) in the closed position and is positioned beside and/or below the nozzle (20) in the first open position.

Abstract: A powder dispenser (16) for metal-binder jetting is proposed. The powder dispenser (16) comprises a blade assembly (42) having: a first blade (44) and a second blade (46). The first blade (44) and the second blade (46) are separated, form a space (48) between them for holding a metal powder and a slit (18) for dispensing the metal powder, and the slit (18) has a width that is adjustable. A powder dispensing system (10) for metal-binder jetting is also proposed. The system (10) comprises a powder dispenser (16) having a slit (18), a dispenser support (20) configured to move the slit (18) between a refilling position and a dispensing position, and a rake (22) positioned between the refilling position and the dispensing position, wherein the rake (22) is arranged to scrape off metal powder at the slit (18).

Abstract: According to a first aspect of the present disclosure, there is provided an additive manufacturing method. In the method, regions of successively-deposited layers of granular construction material are bound together so as to form a three-dimensional structure of bound material extending through and between the layers. The method comprises depositing a first granular construction material as a layer into a build region. The method comprises selectively binding regions of the first granular construction material together to form bound regions within the layer. The method comprises removing unbound granular construction material from the layer so as to provide at least one void in the layer. The method comprises depositing a second granular construction material into the build region so as to fill the at least one void. The method comprises selectively binding regions of the second granular construction material together to form bound regions within the layer.
