Abstract

Particle Bed 3D Printing by Selective Cement Activation (SCA) has the capability to produce high resolution and freeform elements, which offer new possibilities in terms ofresource-efficient and architectural design. In this paperwe present possibilities to enhance the mechanical properties of SCA-printed specimens by curing. Therefore, the focus of this study is to systematically investigate the effect of various curing conditions for two specimen series varying in water cement ratio (0.3 and 0.5): i) under water storage for 1, 3, 7, 21, 28 days and subsequent storage at 20 °C and 65% relative humidity and ii) storage at varying relative humidity (65% and 100% at 20 °C). The specimens are evaluated in terms of mechanical performance (28 d compressive strength), geometrical precision, water distribution over the cross section and calorimetry measurements in order to characterize the remaining hydration potential of the activated cement before and after curing. It is shown that suitable curing can lead to a significant better mechanical performance of the specimens. This is especially interesting for specimens with a low w/c-ratio, where the geometric precision is high. The effect of improved mechanical performance due to curing is attributed to a homogenous distribution of the curing medium water in the specimen. This enables a higher degree of hydration of the cement in the cured specimens,which is shownwith the calorimetry measurements. Finally, the results are discussed regarding their practical applicability.
