Abstract: Provision is made of an apparatus and a method for the manufacture of three-dimensional objects (3) by local solidification of layers of a building material at positions corresponding to the respective cross-section of the object (3), by exposure to electromagnetic or particle radiation. The apparatus comprises a temperature measuring assembly (13) for non-contact measurement of the temperature of the building material in a measurement region (14) which is a partial region of the layer of the building material, and comprises further a position adjustment device (15) for altering the position of the measurement region (14) of the temperature measuring assembly (13) independently of the alteration of the position of the region exposed to the radiation energy. This apparatus can be used to actively access a not exposed region of the surface for measuring the temperature of each layer and to detect a temperature distribution by altering the position of a measurement region (14) in a layer.

The remote computer server will evaluate the data received and respond with a data packet (making recommendations on further glucose measurement, exercise, diet, insulin requirements or other).
Abstract: 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 (5) or a previously applied layer after having lowered the support (5) by the amount of one layer thickness; selectively solidifying the powdery material (11) by energetic radiation (8, 8?) 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, a reduced working field (13) is additionally realized, in which the powdery material (11) is applied and radiated by less than the maximum length (L) and/or by less than the maximum width (B) of the maximum working field (6).
