Patent Abstract

The invention relates to a method and a device for producing a component by means of 3D multi-material pressure and to a component part produced therewith, wherein metallic and ceramic pastes, mixed with powder and binding agents, for producing the component are applied in layers by means of an extrusion process and are shaped, and the printing process is monitored by means of a monitoring device in such a way that defects in the pressure are detected by means of a camera and the defects are eliminated and/or overfilling or underfilling of each printed layer in relation to the extrusion quantity is monitored by means of a camera and/or temporary blockages in the extrusion nozzle are detected by monitoring the pressure in the region of the extrusion nozzle and released by increasing the pressure. The device comprises a corresponding monitoring device. The device can also have a mixing and feeding device with a vacuum mixing container which is connected to a vibration device. The device can comprise a ceramic construction platform having a porous structure. The component has a lattice structure with beads which are deposited at a distance from one another on a plane.
