Abstract

A method for producing a molded body is proposed, comprising: applying a layer of particles and applying a binder and curing a molded body; and a device for producing a metallic or ceramic molded body, having a storage volume, which is configured for receiving a suspension of metallic or ceramic particles that are dispersed in a suspension fluid, a layer-forming application device, which is configured for removing an amount of suspension repeatedly from the storage volume and transferring it into a working volume and applying it there as a layer, a dehumidifying device, which is configured for dehumidifying the applied layer in the working volume, a binder application device, which is configured for applying a binder locally to the dehumidified layer in accordance with a layer model of the molded body to be produced, in such a way that particles in the dehumidified layer are adhesively bonded locally to one another and optionally in addition to particles of at least one layer lying under the dehumidified layer, and a demolding device, which is configured for demolding the molded body by detaching binder-free residual material from the particles bonded to another with the aid of the…
