Title: (EN) Apparatus for additive manufacturing of three-dimensional objects
Abstract: front page image
(EN)

An apparatus (1) for additive manufacturing of three-dimensional objects (3) by successive, selective layer-by-layer exposure and thus successive, selective layer-by-layer solidification of construction material layers of construction material (4) that can be solidified by means of an energy beam. The apparatus can include a process chamber (14) comprising a working plane (A) with a first working plane area (A1) and another working plane area (A2), a coating device (6) provided for forming construction material layers to be exposed selectively and to be solidified selectively in the construction plane (E) and comprising a coating element assembly group (8) which is movably supported, at least one coating element, a shielding device (18) provided for shielding the second working plane area (A2), wherein the shielding device (18) can include at least one shielding band (20) guided movably along supporting points (19).
