Beschreibung
Zusammenfassung:	An infrared lamp assembly for an apparatus for the formation of three-dimensional objects by consolidation of particulate material, the assembly comprising: an elongate infrared lamp extending along a lamp axis, an elongate shield extending parallel to and along one side of the axis of the lamp, and a support structure holding at least one of the ends of the lamp and of the shield, wherein the elongate shield at least partially bounds the space to one side of the lamp, and wherein the assembly provides a lower opening below the lamp and an upper opening above the lamp, such that, in use, radiation generated by the lamp is able to radiate through the openings and away from the lamp in directions not bounded by the shield.
