Design and Experimental Investigation of a 3D Printing Nozzle for Rapid-Hardening Concrete Based on Fluent-EDEM
To address the clogging issue commonly encountered with rapid-setting and hardening concrete, a liquid–solid separation 3D printing nozzle was proposed based on coupled EDEM–Fluent simulations, and its printing performance was verified. First, finite element models of different nozzle types were established, and Fluent...
