20130302575 | METHOD AND MATERIAL SYSTEM FOR BUILDING MODELS IN LAYERS - The present invention describes a method for building models in layers, wherein a first material and subsequent thereto selectively a second material are applied in layers in a build space, and these two application steps are repeated until a desired model is obtained. The two materials form a solid object in a suitable mixing ratio, the first material including a particulate material and the second material being applied with the aid of a print head. The first material, the second material and/or the particulate material include one or more diamines and/or one or more dicarbonyl compounds as the binder. | 11-14-2013 |
20130234355 | DEVICE AND METHOD FOR CONSTRUCTING A LAMINAR BODY COMPRISING AT LEAST ONE POSITION ADJUSTABLE BODY DEFINING THE WORKING AREA - The invention relates to a device ( | 09-12-2013 |
20130199444 | APPARATUS FOR PRODUCING THREE-DIMENSIONAL MODELS BY MEANS OF A LAYER BUILD UP TECHNIQUE - The present invention relates to a device for producing three-dimensional models by a layering technique, at least one print head ( | 08-08-2013 |
20130029001 | DEVICE FOR PRODUCING THREE-DIMENSIONAL MODELS - The present invention relates to a device for man facture of three-dimensional models by means of a 3D printing process, whereby a spreader device is used to deposit particulate material in layers on a build platform and the particulate material flow, which occurs perpendicular to the spreading direction, is transferred into containers that are actively cleaned by sliders or brushes at the spreader device. It exploits the fact that particulate material that is moves dynamically can only bridge small height differences. The arrangement can be implemented in a space-saving manner beneath the spreading plane. | 01-31-2013 |
20130026680 | METHOD AND DEVICE FOR PRODUCING THREE-DIMENSIONAL MODELS - The present invention relates to a method for producing three-dimensional objects based on computer-provided data, whereby a material is deposited in layers in a process chamber and the material is selectively solidified and/or bonded using a bonding apparatus and/or a solidifying apparatus in the process chamber, these steps being repeated. A conveyance of the material proceeds during the build process and proceeds continuously, sequentially and evenly up to an unpacking position. | 01-31-2013 |
20130000549 | DEVICE AND METHOD FOR PRODUCING THREE-DIMENSIONAL MODELS - The present invention relates to a device for manufacturing three-dimensional models by means of a 3D printing process, whereby a build platform for application of build material is provided and a support frame is arranged around the build platform, to which said support frame at least one device for dosing the particulate material and one device for bonding the particulate material is attached via the guiding elements and the support frame is moveable in a Z direction, which essentially means perpendicular to the base surface of the build platform. In so doing, the device provides a material feeding device having a particle material container to supply particulate material in batches from the storage area to the dosing apparatus and to do so with the least possible amount of shearing forces and without significant interaction with the atmosphere. | 01-03-2013 |
20120291701 | DEVICE FOR PRODUCING THREE-DEMENSIONAL MODELS - The present invention relates to a device for manufacture of three-dimensional models by means of a 3D printing process, whereby the build material is deposited on a build platform in layers and the build platform is moveable in the Z-direction and one or several drive units and one or several guide elements is/are provided to move the build platform. In so doing, drive units and guiding elements are arranged in such a way that a movement of the drive units is decoupled from the movement of the guiding elements. | 11-22-2012 |
20120097258 | METHOD AND DEVICE FOR SWITCHING A PARTICULATE MATERIAL FLOW IN THE CONSTRUCTION OF MODELS IN LAYERS - The invention relates to a method for switching a particulate material flow in the construction of models in layers, wherein particulate materials are fed to a subsequent method step from a container having an opening in the direction of a workpiece platform. The particles in the container are exposed to a vacuum and to overpressure. | 04-26-2012 |
20110308755 | METHOD FOR THE LAYERED CONSTRUCTION OF MODELS - Described is a procedure for layered composition of models, whereby at least a first material is applied to an assembly platform, followed by selective application of a second material layer; these two application steps are repeated until the required model is achieved and both materials form a solid structure in an appropriate mixture ratio. The first material comprises a moulding sand; the first and/or second material comprises a bonding agent encompassing a salt-crystal binder and/or protein binder. | 12-22-2011 |
20110223437 | METHOD FOR THE LAYERED CONSTRUCTION OF PLASTIC MODELS - The invention relates to a method for implementing layered construction of plastic models, whereby a first material is applied to a building platform and thereupon a second material is selectively applied and these two application steps are respectively repeated layer after layer until the desired model is obtained. The two materials form a solid body when a suitable mixture ratio is used. The first material includes a particle material and the second material is applied via a print head and contains N-vinylformamide. | 09-15-2011 |
20080233302 | Method and Device for Production of a Three-Dimensional Article - The invention relates to a method and device for production of a three-dimensional article from a material, by means of layered application. According to the invention, a dropwise application is carried out, whereby drops of reaction components are ejected by a nozzle arrangement ( | 09-25-2008 |
