| Abstract: | Material extrusion MEX of complex thermoplastic structures often depends on the reliable printing of a water-soluble support structure. The material of choice is typically polyvinyl alcohol (PVA), which is difficult to use in ceramic MEX printing due to a limited printing compatibility with most ceramic feedstocks (poor layer adhesion). A new thermoplastic feedstock concept was developed as temporary water-soluble support material on the basis of NaCl mixed with a commercial injection molding binder system. Additive manufacturing enables the introduction of new molding concepts not only through the direct printing of ceramic green bodies with or without support material, but also generally through the production of water-soluble mold materials. The particular advantage of additive manufacturing's virtually unlimited geometry complexity then additionally allows the production of undercut models, threads, channels, and other otherwise complicated mold elements. The use of soluble molds instead of direct 3D printing of ceramic green bodies thus offers the possibility to partially circumvent existing limitations of currently available technologies and materials. |
