A device and a process for producing three-dimensional objects is disclosed. The device has a container () for a medium () and a three-dimensionally positionable dispenser () for release of a material (), the addition of which to the medium () leads to the formation of solid structures, into the medium (). Addition of the material () by moving the dispenser in XYZ direction on a platform () below the filling height of the first material () in the container () leads to the formation of three-dimensional objects.

Device and method for the production of three-dimensional objects

A process for fabricating dental form pieces for dental restoration and replacement parts is provided and includes the step of applying a material, on a firm support or a fluid medium, by a three dimensional plotting technology in a layer by layer manner. The material has micro cords and/or micro drops which include at least one of a meltable, polymerizable, polycondensable, and polyaddable constituent element that is an unfilled monomer, a reinforced monomer, oligomer, polymer, or a ceramic element. The process also includes the step of hardening the applied material by cooling of the material, chemical reaction, polymerization with thermal handling, or polymerization by irradiation of the material with UV or visible light.
