Technology of 3D Printing of Light Ceramics for Construction Products

A 3D-printer for working with plastic mineral mixtures is developed, its kinematic scheme and principle of operation are described. The results of experiments on printing simple forms of plastic clay, using a piston-type extruder, are presented. In relation to an additive technology, a list of technological properties of mineral masses is defined The optimal amount of chemical additives has been established, which provides an increase in the uniformity of the raw material mass for printing products from light ceramics.
