Method for applying particle material including a metering system and leveling element
This document describes a process and a device for applying fluids, specifically particle material, on an area to be coated, which is viewed in forward moving direction of the coater, chat fluid is applied on the area to be coated and then a levelling element is run over the applied fluid, whereby the fluid is led from a metering system provided with an opening, which oscillates when applying the fluid. The opening shall be designed in such a way that when the metering system is at a standstill this is closed by forming an angle of repose of the fluid.

B29C 41/12 - Spreading-out the material on a substrate
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.

Self-hardening material and process for layerwise formation of models
The invention relates to a self-hardening material for layerwise construction of three-dimensional components, whereby the material comprises at least one particulate material and a separately applied bonding agent for bonding the particulate material, and has a setting time which is at least several times as long as the application time of a particulate layer.
The present invention relates to a method for conveying particulate material during the manufacture of patterns in layers, wherein powder is conveyed out of a reservoir into a spreader unit and, if applicable, excess powder fed to the spreader unit is again conveyed back into the reservoir and wherein this conveying takes place in a closed conveying circuit.
A method or procedure for the construction of a laminated compound or mould made up of a number of layers of particle material on top of each other, which are hardened and joined to each other in predetermined onsite areas, which can differ from each other depending on position and expansion, so that from the predetermined hardened areas of the laminated compound at least one mould is formed. The layers are deposited individually one after another in predetermined layer thickness by the dispensing of particle material from a dispensing device during its movement above a working field and according to computer data in predetermined areas.
The instant invention relates to a device and method for manufacturing patterns in layers. The device includes an auxiliary frame, a vertically displaceable build platform, a dispensing device for applying a binder material onto the build platform, a mounting platform, a mounting platform, and a spreader device for applying particulate material. The mounting platform preferably is connected to the auxiliary frame and includes a cut-out for the build platform. The dispensing device, the spreader device, and the build platform are connected to the mounting platform, so that the dispensing device, the spreader device and the build platform are cable of being mounted, adjusted, and wired to the mounting platform while located outside the auxiliary frame.
