Abstract

An apparatus (1) for the additive manufacturing of at least one three-dimensional object (2) by selectively compacting layer by layer at least one compactible building material (3) by means of at least one energy beam (5) generated by at least one radiation generating device (4), comprising at least one radiation generating device (4) for generating at least one energy beam (5) for compacting at least one compactible building material (3), at least one coating device (8) for carrying out at least one coating operation to apply a defined building material layer (9) of at least one compactible building material (3) to a building plane (10) or to a building material layer (9) of at least one compactible building material (3) that has previously been applied in the course of carrying out a previous coating operation, and also at least one recording device (11) for recording layer information describing.
