THE POSSIBILITY OF THREE-DIMENSIONAL PRINTING WITH SILICATE MASSES USING CERAMIC AND HYDRATION BINDERS

Abstract

The 3D printing technologies have appeared for a long time and are successfully used in a number of industries. The activities of many leading companies in the creation of layouts, models and prototypes of units, assemblies, products are practically not carried out without the use of 3D printing. The following are batch production technologies with high productivity combined with low cost, comparable to traditional methods of manufacturing products. The production of various products from silicate masses in an additive manner is seriously constrained by a number of issues due to the specifics of the material itself. One of them - achieving high physical and mechanical characteristics is possible only after hydration (for cements) or heat treatment (ceramic masses) of the product. Significant influence is exerted by the method of manufacturing the product. The most convenient and least energy-consuming method (in comparison with the powder 3D printing methods using laser sintering) is layer-by-layer slip casting or plastic extrusion, however, there are some unresolved problems. This paper highlights the key problems of using the additive method of manufacturing structural products on ceramic and hydration bonds using plastic and rigid masses in combination with vibration effects.
