利用工作区限制来再生制造三维物品的设备和方法
摘要：
本发明涉及用于在设备中再生制造三维物品的设备和方法，包含下列的步骤：a)在设备的托架或之前涂覆的层上逐层地涂覆粉末材料(11)；b)在与物品(3)的在涂覆的层中的横截面相对应的位置上选择地固化粉末材料；c)重复步骤a)和b)，直至制成物品(3)；其中设备具有一个两维的最大工作区(6)，其具有一个最大长度(L)和一个最大宽度(B)，在该最大工作区中能够涂覆粉末材料；并且该方法具有正常的运行模式和具有借助于减小的工作区(6)进行的特殊的运行模式，在所述正常运行模式时在最大工作区(6)中涂覆粉末材料，在特殊运行模式时在小于最大工作区的最大长度和/或小于最大工作区的最大宽度的范围上涂覆粉末材料。
摘要（英）：

The present invention relates to a device and a method of generatively manufacturing a three-dimensional object in a device, comprising the following steps: layerwise applying a powdery material (11) onto a support or a previously applied layer; selectively solidifying the powdery material at locations corresponding to the object (3); repeating the steps a) and b), until the object (3) is completed. The device defines a two-dimensional maximum working field (6) with a maximum length (L) and a maximum width (B), in which the powdery material (11) can be applied and solidified. According to the invention, the method has a normal operation mode and a special operation mode by means of a reduced working field (6), in the normal operation mode, the powdery material is applied in the maximum working field (6); and in the special operation mode, the powdery material (11) is applied and radiated in a range less than the maximum length (L) and/or by less than the maximum width (B) of the maximum working field (6).
