Beschreibung
Zusammenfassung:	The invention relates to an apparatus and method for producing an object by means of 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 invention, a registering device is provided for registering a characteristic of a calibration area related to the surface level of the bath of material. Furthermore, a control unit connected to the registering device is provided. 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. 本发明涉及用于通过增材制造生产物品的设备和方法。该设备包括：处理腔，该处理腔用于接收可通过暴露于电磁辐射而凝固的材料浴；支承件，该支承件用于将物品相对于材料浴的表面层面定位；以及凝固装置
