Abstract: Several polymeric materials and different macrostructures produced by additive manufacturing were tested as templates for the production of ceramic foams with defined macrostructure. The polymer templates can be coated by different techniques; in this study, cold spraying with carbon-bonded alumina as well as flame spraying with alumina were used. After the subsequent thermal treatment of cold-sprayed templates, the ceramic bodies sustain the designed macrostructure.
