Abstract

3D printing by extrusion/deposition is currently the most widely used process in the field of digital construction [WAN 16]. This automated construction process is a complex process that can be broken down into several steps: pumping the material, extruding it and depositing it. For each step of the printing process, the fresh cement-based materials must have complete control over the properties which guarantee both the flow of the material during the initial stage of the process, and its stability after being deposited. Traditionally, in laboratories, a robotic arm is used to deposit the materials transported by a mortar pump, layer-by-layer, following a path determined by the digital model of the structure to be printed (Figure 2.1). Concrete pumps are also used as a method of transporting the materials on construction sites or in prefabrication factories. Conversely, various technical solutions are used to move the extrusion (or printing) head. This is fixed on various supports that allow the effector to be moved along the programmed paths: traveling cranes [KHO 06], articulated arms on mobile machinery [LEA 12, KHO 05], fixed supports [API 18, XTR 18] or conventional building site lifting means that are repurposed from their original use [NER 16a].
