Abstract
An apparatus for the generative production of a three-dimensional object by successive, selective layer-by-layer solidification of construction material layers of a solidifiable construction material by means of at least one energy beam, comprising at least one device for generating at least one energy beam for selective layer-by-layer solidification of individual construction material layers of a solidifiable construction material, wherein the device is configured to generate an energy beam directed directly onto a construction plane, and an exhaust device which is configured to exhaust non-solidified construction material detached from the construction plane during processing and/or process gases arising during processing, wherein the exhaust device comprises at least one exhaust element through which a suction flow may or does flow, wherein at least one passage opening is formed in the at least one exhaust element for passage of an energy beam generated by the device and directed directly onto the construction plane.
