Beschreibung
Zusammenfassung:	Apparatus (1) for the additive manufacture of at least one workpiece (2), comprising at least one light source (3) for emitting light (4) in an operating state, comprising a support element (6), which is transmissive to the light and, in the operating state, is arranged substantially horizontally such that meltable granules (9) can be arranged on an upper side (7) of the support element, wherein, in the operating state, the path of rays of the light is such that the light impinges on the support element from the underside with at least one directional component parallel to a first direction (10), which extends from an underside (8), opposite from the upper side, of the support element to the upper side, also comprising a workpiece holder (11), which is arranged behind the upper side, as seen in the first direction, wherein the support element and/or the workpiece holder can be moved by at least one displacement means (12) with at least one directional component parallel and antiparallel to the first direction, and also comprising at least one focusing means (5), which is designed to focus the light behind the upper side, as seen in the first direction.
