  • Patent number: 9186847
    Abstract: A method for producing a three-dimensional object by selective solidification of a build material includes irradiating a surface of a mask with at least one radiation source. The mask is disposed at a distance from a build plane and an optical imaging system is used to produce a reproduction of the mask on the build plane.

  • Patent number: 8905744
    Abstract: A transport container for use in a device for producing a three-dimensional object of selective solidification of a build-up material deposited in layers, in which the device has a process chamber closed during operation, where the three-dimensional object is produced in layers. The transport container has a container, in which a height-adjustable platform is arranged, on which the three-dimensional object is produced in layers. The process chamber has first and second sections in which the second section can be separated from the first section and operated in a separate state independently from the device and also can be connected to the first section to produce an operating state of the device.

  • Patent number: 8399167
    Abstract: The present invention relates to a toner composition for forming a masking pattern for use e.g. in connection with a method of building up a three-dimensional body from a large number of mutually connected layers of powder particles that are bonded to each other using radiant heat. The toner composition consists of powder particles that arc able to withstand a temperature of at least 200° C. without sticking together. It also relates to a developer that comprises the toner composition and carrier particles and a method in connection with the production of a volume body by using a toner composition or a developer according to the invention.
