Resumen
The influence of the molecular weight of carboxymethylcellulose as solid binder for additive manufacturing was studied. Three sodium carboxymethyl celluloses with different molecular weights were added to a stoneware. The powders were used on a binder jetting machine using a water-based liquid as a bonding agent. Differential Thermal Analysis and Fusion Tests (Hot Stage Microscope) were carried out to determine the correct firing cycle. The printed parts were characterised before and after firing. The density, roughness, pore size and mechanical strength of the sintered samples were tested. © 2022 The Authors
