Abstract
A method for the production of blanks for sintered glass bodies for glass seals, wherein with a 3D printing method, a number of layers are arranged one above the other. In a first step, a first layer of a glass powder is spread on a surface, a computer-controlled stream of a printing fluid is directed to selected areas of the first layer in a pattern prescribed by the computer. In a second step, a further layer of the glass powder is spread over the first layer and on it, a computer-controlled stream of printing fluid is directed to selected surfaces of the second layer in a pattern prescribed by the computer, the two steps are repeated until the blank is formed. The glass powder components contain SiO, NaO, KO, CaO, MgO, BO, BaO, AlO, PbO, LiO and SrO as well as a solid binder made of dextrin.
