Abstract
A printhead for three-dimensional printing of concrete includes a main body and a regulator device. The main body includes a multi-stage, convergent-divergent cylinder, shearing blades, a pressure chamber, and a secondary inlet. The pressure chamber surrounds the cylinder for temporary storage and regulated processing of a secondary fluid. The secondary inlet transfers the secondary fluid from the pressure chamber to the multi-stage, convergent-divergent cylinder to form a mixture, which is discharged from the printhead. The printhead can, for example, be used for additive manufacturing of cement-based materials.
