Effect of curing methods during a long time gap between two printing sessions on the interlayer bonding of 3D printed cementitious materials

A good bond between the layers of 3D printed cementitious materials is a prerequisite for having high structural rigidity for the printed elements. However, the influence of printing process on an interlayer bond is still not well understood. This study investigates the influence of curing methods (i.e., air curing, plastic film covering, wet...

A review of methods on buildability quantification of extrusion-based 3D concrete printing: From analytical modelling to numerical simulation

Herein, different kinds of methods for buildability quantification of 3D concrete printing are reviewed, including experimental approaches, analytical modelling, and numerical simulations. A brief introduction on printing process is first given. This discusses the material properties in different stages. Material printability, which...
