    摘要: The present invention relates to a method and a device for manufacturing a three-dimensional object, wherein the object is generated by successively solidifying single layers of fluid or powdery solidifiable building material by the action of electromagnetic radiation. The method comprises steps for emitting a first pulsed electromagnetic radiation onto a first area of a layer of the building material, and for emitting a second continuous electromagnetic radiation onto a second area of the layer of the building material.

    摘要: A device for the making of a three-dimensional object by means of layer by layer consolidation of a powderlike construction material by electromagnetic radiation or particle beam has a control unit that controls an irradiation device such that the powder particles of the construction material are bonded together at the sites where the radiation impinges on the construction material. A selective heating device is designed so that any given partial surface of the construction field can be heated before and/or after to a plateau temperature, which is significantly higher than the temperature of at least a portion of the construction field outside the partial surface. The control unit actuates the selective heating device such that the partial surface has a predefined minimum distance from the edge of the construction field.

    摘要: A device for the making of a three-dimensional object (3) by means of layer by layer consolidation of a powderlike construction material (11) by electromagnetic radiation or particle beam has a height-adjustable carrier (2), on which the object (3) is built, and whose horizontal dimension defines a construction field (5). Furthermore, an irradiation device (6, 9) is present for directing the radiation onto regions of an applied layer of the construction material within the construction field (5) corresponding to an object cross section (30). A control unit (10) controls the irradiation device (6, 9) such that the powder particles of the construction material (11) are bonded together at the sites where the radiation impinges on the construction material. A selective heating device (18a, 18b) is designed so that any given partial surface (19) of the construction field (5) can be heated before and/or after to a plateau temperature, which is significantly higher than the temperature of at least a portion of the construction field (5) outside the partial surface (19). The control unit (10) actuates the selective heating device (18a, 18b) such that the partial surface (19) has a predefined minimum distance (d) from the edge of the construction field (5).
