Beschreibung
Zusammenfassung:	SOLUTION: The present invention relates to an apparatus and method for producing an object by additive manufacturing. The apparatus comprises: a process chamber for receiving a bath of material which can be solidified by exposure to electromagnetic radiation; a support for positioning the object in relation to the surface level of the bath of material; and a solidifying device for solidifying a layer of the material on the surface level by means of electromagnetic radiation. According to the present invention, a registering device is included for registering a characteristic of a calibration area related to the surface level of the bath of material. Further included is a control unit connected to the registering device. The control unit is arranged for using the characteristic of the calibration area obtained by the registering device for controlling the position of the electromagnetic radiation emitted by the solidifying device.SELECTED DRAWING: Figure 3 【解決手段】本発明は、積層造形によって物体を製造するための装置および方法に関する。装置は、電磁放射線への暴露によって凝固させることができる材料の槽を受け入れるための処理チャンバと、材料の槽の表面レベルに対して物体を位置決めするための支持体と、電磁放射線によって表面レベル上で材料の層を凝固させるための凝固装置とを備える。本発明によれば、材料の槽の表面レベルに関連する較正領域の特性を記録するための記録装置が設けられる。さらに、記録装置に接続された制御ユニットが設けられる。制御ユニットは、凝固装置によって放射される電磁放射線の位置を制御するために、記録装置によって得られた較正領域の特性を使用するように構成される。【選択図】図３
