Abstract

This paper proposes a specific extrusion method for 3D printing of mortar called free deposition by the authors. It consists in letting a fine mortar flow through a moving nozzle above a support, here EPS foam. The aim is to obtain a regular lace, thus to avoid instability phenomena like coiling, and ensure a regular diameter, without stretching the lace. A rheological characterisation is proposed and is experimentally tested. This work takes place in the context of the building of space trusses in 3D printed concrete thanks to progressively assembled EPS foam blocks acting as support.
