摘要： A powder deposition apparatus for producing a component comprises a base plate, an annular stack of heating elements, accommodating the base plate, one or more insulating elements, being interleaved between adjoining heating elements, a mechanism operable to deposit a plurality of layers of a powder material onto the base plate, and a laser energy source operable to selectively fuse a portion of the deposited layer. The annular stack of heating elements is sized such that a predetermined clearance is defined between the component and the annular stack of heating elements. As successive layers of the powder material are deposited onto the base plate, the base plate is lowered into the stack of heating elements, the heating elements being actuated sequentially to maintain a pre-determined temperature profile in the deposited layers.

摘要： 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.

摘要： A printing apparatus is for printing a three-dimensional object, comprising an operative surface, an energy source for emitting at least one energy beam onto the operative surface and at least one supply hopper for dispensing powder onto the operative surface, wherein the powder is adapted to be melted by the energy beam. The supply hopper is configured such that powder being dispensed by the supply hopper has an airborne density when travelling from the supply hopper to the operative surface, and wherein the density provides that the powder is not melted by the energy beam when the powder is travelling to the operative surface.
