  • Self-hardening material and process for layerwise formation of models
    Patent number: 9676143
    Abstract: 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.
    Type: Grant

  • Method for applying particle material including a metering system and leveling element
    Patent number: 9463488
    Abstract: 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.
