Abstract

A process and an apparatus for producing 3D moldings, wherein a spectrum converter is used. Said converter is defined as a means which absorbs a radiation, for example electromagnetic thermal radiation, and radiates or emits one or more defined wavelength ranges; the spectrum converter is here irradiated by an emitter of an electromagnetic thermal radiation (shortwave or longwave radiation), i.e. by a lamp or an emitter, for example an overhead emitter or a sintering unit, and then emits a defined electromagnetic thermal radiation

Abstract

The invention relates to a method for producing 3D shaped articles, in which method: a suspension comprising metallic, ceramic or polymer particle material or cement-bound materials is applied as a suspension layer to a construction platform to produce a layer; the layer thus applied is at least partially dried; a binder is selectively applied; and the selectively applied binder is solidified; these steps being repeated until the desired 3D shaped article has been obtained; where necessary, the particle material which has not been solidified by means of the binder is removed; and the 3D shaped article is unpacked; wherein the suspension for producing a layer is applied by means of a sieve plate, which is positioned onto the last applied layer on the construction platform and through which the suspension is applied to the last particle material layer; and wherein the sieve plate is removed again before the selective application of the binder.

Abstract

The present invention relates to a method and a device for producing three-dimensional objects based on computer-provided data. Material is extruded on a surface of a workpiece (e.g., in two-dimensions). The workpiece is then moved incrementally so that additional material can be extruded on the new surface of the work piece. These steps are repeated until the 3-dimensional object is completed. The present invention also relates to a device including an extruder system for extruding a build material in multiple directions on a surface of a workpiece, and a conveying component for moving the workpiece incrementally for extruding additional material on the new surface. The method and device preferably allows for the continuous construction of three-dimensional objects.

Abstract

The invention relates to a device for constructing a laminar body from a plurality of superimposed layers of free-flowing material, in particular particulate material, and a build platform within a working area. The layers are solidified in locally predetermined regions by the action of binders and are joined together so that at least one moulded body is formed by the solidified and joined regions of the layers. The device comprises a discharging device movable back and forth over the working area in at least one discharge direction and having at least one discharge opening from which the free-flowing material can be discharged in individual superimposed layers during the movement of the discharging device.

Abstract

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.

Abstract

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.
