title = "3d printing of concrete structures using the selective binding method – effect of concrete technology on contour precision and compressive strength",
abstract = "3D printing (3DP) is a promising production method to minimize the costs of bionic-optimized mate-rial-saving structures. The investigated 3DP method “selective binding” generates a concrete structure layer by layer based on a computer model by applying a thin layer of a dry material followed by local application of a fluid for hardening. The aim was to determine the effect of concrete technology on the contour precision and the compressive strength of printed cylinders by varying the permeability of the dry material (aggregate) and the yield stress of the fluid (cement paste). First results show that the horizontal contour precision increased with decreasing permeability and yield stress. The strength increased with increasing paste intrusion height.",
