Abstract
A device for producing a three dimensional object from a powdery material by solidifying the powdery material through the application of energy includes a working surface, an application device for applying the powdery material onto the working surface, and a solidifying device for solidifying the powdery material applied onto the working surface. The application device can apply predefined, locally different amounts of powdery material and includes a transfer device, which can be magnetized and/or electrostatically charged and discharged, as well as a magnetizing and/or charging device.
Claims15
A device for producing a three dimensional object from a powdery material by solidifying layer by layer the powdery material through the application of energy, the device comprising:
- a working surface;
- an application device configured to apply predefined, locally different amounts of powdery material of the powdery material onto the working surface;
- and
- a solidifying device configured to solidify the powdery material applied onto the working surface,
- wherein the application device comprises
- a transfer device, which can be magnetized and/or can be electrostatically charged and discharged and which is configured to transfer the powdery material to the working surface;
- and
- a magnetizing or charging device configured to magnetize or electrostatically charge and discharge the transfer device.
A method for producing a three dimensional object from a powdery material by means of selective solidification through the application of energy, wherein the object is produced layer by layer in such a way that a layer of a powdery material is applied and solidified on a working surface;
- and wherein applying of the layer of powdery material comprises the steps of:
- a) positioning a transfer device for applying the powdery material on the working surface over or in a supply device;
- b) magnetizing or electrostatically charging the transfer device at predefined positions, so that the powdery material is deposited on the transfer device;
- c) moving the transfer device on or over the working surface;
- d) demagnetizing or discharging the transfer device at predefined positions, so that the powdery material falls onto the working surface at predefined positions.
