Abstract
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.
