  • Patent number: 8020604
    Abstract: A method for the layered construction of models is disclosed, whereby at least one first material is applied to a building platform and then a second material is selectively applied in layers. Both application steps are then repeated until the desired model is obtained and the both materials form a solid body with a desired mixing ratio. The first material comprises a moulding sand and the first and/or the second material comprises a binder, comprising a crystalline salt binder, or/and a protein binder.

  • Patent number: 7955537
    Abstract: A process to produce models in layers is described, whereby a first material and then selectively a second material is applied in layers on a building platform and these two application stages are repeated until a desired pattern is achieved. The two materials form a solid if a suitable mixture ratio is used and the first material is a material mixture. The material mixture is at least partially prepared prior to each application stage.

  • Patent number: 7879393
    Abstract: The invention relates to a method for applying fluids, especially particle material, on a area that is to be coated, wherein the fluid is applied on the area to be coated in front of a blade when observed from the direction of forward movement of the blade and said blade is then displaced on the applied fluid. The method is characterized in that the blade performs an oscillation similar to a rotational movement.

  • Patent number: 7874445
    Abstract: An interchangeable container for a system for building a mold body by forming superimposed layers of granular material, the granular material locally and selectively hardened layer by layer. The container includes a bottom structure that is displaceable in the interior of the container in a direction in parallel with the container side walls and at least one spindle drive having a vertical screw spindle rotatably mounted in a container side of the container, and a spindle screw nut on which the bottom structure is supported. The bottom structure can be lowered step by step in the interior of the container by the spindle drive.

  • Patent number: 7799253
    Abstract: The invention relates to a method and a device for applying for a flowable material, especially a particulate material, in individual superimposed layers across a support (50), the flowable material being first filled from a stationary feed station (10) into a storage container (24) of an application device. In the application device (30), which travels back and forth across the support, the flowable material is distributed inside the storage container across the entire length of the device and is then metered through a slot into a metering shaft in such a manner that the filling level in the metering shaft remains constant during application of the flowable material from the metering shaft onto the support.

  • Patent number: 7748971
    Abstract: This invention relates to a method for use in dispensing fluids especially particulate matter on to a surface to be coated, comprising a blade traversing along said surface, whereby the fluid is dispensed in front of said blade on to said surface, whereafter said blade is swept across the dispensed fluid such that it imparts vibrations. The fluid (5) is fed on to said surface through the bottom outlet of a container (3) vibrated cooperatively with the blade (7).

  • Patent number: 7204684
    Abstract: The invention relates to an interchangeable container (1) for a device used to construct models. Said container forms a substantially delimiting frame, into which a workpiece platform (2) that acts as a base can be inserted. The interchangeable container (1) contains a support (3) onto which the workpiece platform (2) is introduced.

  • Patent number: 7137431
    Abstract: Described herein is a device for pattern building in layers, which has a frame (1), a vertically movable and interchangeable workpiece platform (17), and a material feeder with a spreader (4), whereby the spreader (4) serves to feed material from a storage bin situated in the workspace above the workpiece platform (17), and the workpiece platform (17) is fixed at least when building a pattern. The workpiece platform (17) is accordingly loaded into the device from one side and unloaded from the other side of the device.

  • Patent number: 7004222
    Abstract: The invention relates to a device for manufacturing models layer by layer. The inventive device comprises a frame (1), a vertically adjustable and exchangeable workpiece platform (17)m and a device for feeding the material comprising a coating applicator (4). Said coating applicator (4) serves to feed material from a storage container to a process zone above the workpiece platform (17), said workpiece platform (17) being fixed in the device at least during manufacturing of a model. The workpiece platform (17) is introduced on the one side of the device and extracted on the other side of the device.

  • Patent number: 6423255
    Abstract: A method for manufacturing a structural part by a multi-layer deposition technique, in particular a part in the form of a casting mold or a casting core, a porous first layer of bulk particulate material consisting of particles of a predetermined particle size being deposited to form a layer of a predetermined layer thickness, a predetermined dose of liquid binder material being applied onto the layer, so that the liquid binder material penetrates the layer and becomes distributed within the layer and wets the particles of the layer and a predetermined residual porosity of the layer remains after distribution, a predetermined dose of liquid curing agent being selectively applied to a predetermined sub-area of the layer containing the binder material, a second layer being deposited on the first layer containing the binder material and the curing agent and being treated with a binder material and selectively with a liquid curing agent, the curing agent being applied to the second layer before the binder materia
