Abstract: The invention relates to a server for sending and receiving data, in particular for an order control of production orders, wherein the server is adapted to establish a data connection with a plurality of order computers arranged distanced from the server at an orderer location and to receive an order data package containing geometric anatomy information, in particular about a digital dental impression of a patient and address information about the order computer, from each one of these order computers.

Abstract: The invention relates to a stereolithography apparatus comprising: a container for a fluid material curable by radiation, a substrate plate, an actuator means for generating a relative movement between the container and the substrate plate, and an irradiation device for selectively irradiating the material arranged in the container. According to the invention, the actuator means and the irradiation device are mounted on a frame assembly, and the container and the substrate plate are combined to form an assembly and the assembly consisting of the container and the substrate plate is jointly inserted into the frame assembly, detachably secured therein by means of an attachment means and to be jointly removed from the frame assembly.

Abstract: A post-exposure apparatus is disclosed, comprising a reception apparatus for receiving a product produced by stereolithography, a radiation apparatus for irradiating a product received in the reception apparatus, and a movement apparatus, coupled between the reception apparatus and the radiation apparatus, for producing a relative movement between the product received in the reception apparatus and the radiation apparatus. The movement apparatus comprises a first guide apparatus for guiding the relative movement along a first guide path and a second guide apparatus for guiding the relative movement along a second guide path that differs from the first guide path.

Abstract: The present invention relates to a method of producing a (shaped) ceramic or glass-ceramic article, involving the steps of: (a) providing a powder or a powder mixture comprising ceramic or glass-ceramic material, (b) depositing a layer of said powder or powder mixture on a surface, (d) heating at least one region of said layer by means of an energy beam or a plurality of energy beams to a maximum temperature such that at least a part of said ceramic or glass-ceramic material in said at least one region is melted and (e) cooling said at least one region of said layer so that at least part of the material melted in step (d) is solidified, such that the layer is joined with said surface in said at least one region. The invention also relates to ceramic or glass-ceramic articles and their use.
