    Abstract: A printing apparatus is for printing a three-dimensional object having an operative surface; a plurality of supply hoppers for dispensing powder, the powder being adapted to be melted by an energy beam, wherein the supply hoppers are configured to form a plurality of vertically-aligned powder beds adjacent to one another on the operative surface simultaneously; and an energy source for emitting an energy beam onto each powder bed simultaneously to melt or fuse a topmost layer of the powder bed onto an underlying powder bed layer or substrate.

    Abstract: A printing apparatus is for printing a three-dimensional object comprising an operative surface, at least one supply hopper for depositing layers of powder onto the operative surface and an energy source for emitting at least one energy beam onto the layers of powder. The supply hopper and energy source are configured such that when a topmost layer of powder is being deposited onto an underlying layer of powder on the operative surface, the direction travelled by the supply hopper when depositing the topmost layer is different to the direction travelled by the supply hopper when depositing the underlying layer, and at least one energy beam is emitted onto the topmost layer and at least one further energy beam is emitted onto the underlying layer, simultaneously, to melt, fuse or sinter the topmost and underlying layers.

    Abstract: A charged particle propagation apparatus has a generator including a vacuum chamber with a gun therein for discharging a charged particle beam through a beam exit. A higher pressure region adjoins the vacuum chamber at the beam exit and is maintainable at a pressure greater than a pressure of the vacuum chamber. A plasma interface located at the beam exit includes a plasma channel having at least three electrode plates disposed between its first end and its second end. A control system is adapted to apply a sequence of electrical currents to the electrode plates, which cause at least one plasma to move from the first end to the second end of the plasma channel, thereby pumping down the beam exit, and, in use, the charged particle beam is propagated from the vacuum chamber through the, or each, plasma into the higher pressure region.

    Abstract: A printing apparatus is for printing a three-dimensional object. The apparatus includes a frame configured to rotate about an axis; an operative surface mounted to the frame; a powder dispenser mounted to the frame, the powder dispenser being configured to deposit at least one powder layer onto the operative surface; and an energy source mounted to the frame for emitting at least one energy beam onto the powder layer. Rotational movement of the frame causes the operative surface to exert a centripetal force on the powder layer for securing the powder layer on the operative surface.

    Abstract: An apparatus is for forming powder, and includes an energy source for emitting at least one energy beam onto a workpiece, the energy beam being configured to melt the workpiece, at least in part, to form at least one pool of molten material on the workpiece. The apparatus is configured to exert a force on the workpiece causing at least a bead of molten material to be ejected from the pool and solidify to form a particle of powder.
