Abstract

The authors of this study have recently succeeded to formulate geopolymer as a printing material to be used in commercially available powderbased 3D printers for the manufacture of ‘free-form’ components with complex geometries without the use of expensive formwork. This study focusses on postprocessing methods to increase the strength of powder-based 3D printed geopolymers. The effects of curing medium, curing temperature, curing time and loading direction on the compressive strength of the printed geopolymers were investigated. The printed samples were cured in two different sodium (Na)-based and potassium (K)-based alkaline solutions at two different curing temperatures (ambient-temperature (23 °C) and 60 °C) for 7 days and 28 days. The compressive strength of the post-processed geopolymer samples was measured in two different loading directions. The results showed that the post-processed printed geopolymer specimens cured in the Na-based solution exhibited higher compressive strength than that of the specimens cured in the K-based solution. This is true regardless of the curing temperature, curing time and loading direction. In addition, the 28-day compressive strength of the ambienttemperature-cured post-processed printed geopolymer samples was comparable to the 7-day compressive strength of the heat-cured samples. This is true regardless of the curing medium and loading direction.
