The invention relates to a device for producing three-dimensional models in a continuous process, comprising a building surface which has a first end in the direction of movement and a second end in the direction of movement, at least one metering device and at least one strengthening arrangement, wherein the building surface is designed to transport heavy components and the components are able to be transported over the building surface in a substantially distortion-free manner, and a process therefor.
The present invention relates to a method for producing three-dimensional objects in accordance with computer data by repeated application of layers of a particle-containing medium and selective solidification of said medium, wherein a fill of medium is provided on a construction area and a layer of medium is applied to a fill surface area adjoining the construction area with an angle (ß) by means of a coating unit and solidification takes place according to computer data by means of a solidification unit, characterized in that the fill is not moved during construction of the objects.
A system is described for producing three-dimensional models by means of a technique for applying a layer of fluid construction material to a construction platform of an interchangeable container (12), wherein substantially horizontal feeding and removal areas are provided for feeding the construction platform (19) into a construction device and for removing it therefrom. When the construction platform (19) has been introduced into the construction device, it is brought into engagement with the construction device at least in part during a layer application process, and a jaw clamping device that can be brought into engagement with a subsection of the construction platform (19) is provided on the construction device side underneath the construction platform (19) in a position of the construction platform when it has been introduced into the construction device.
The invention relates to a device for constructing models in layers. A region for constructing models, preferably a construction platform, and a material applying device (4, 5) for applying material onto the region are provided. The material applying device (4, 5) is arranged in a movable manner over the region. The material applying device (4, 5) is designed as a portal (1, 1') such that the material applying device can be moved over the region at least via two linear guides (2) arranged at opposite sides of the region, and the material applying device is arranged around the region such that a portal (1, 1') is formed by at least two portions that extend laterally with respect to the region. At least one additional material applying device (4, 5) for applying an additional material onto the region is provided.
A method is described here for the layerwise construction of models, wherein, in a building region, a particulate material is applied layerwise and selectively cured. These steps are repeated until a desired model is obtained. The material comprises in this case a particulate building material and a spray-dried alkali metal silicate solution. Selective activation of the curing proceeds using a water-comprising solution.
