Printable properties of cementitious material containing copper tailings for extrusion based 3D printing
TL;DR: In this article, an environmental friendly cementitious mixture that is compatible with an extrusion-based printing process was proposed, where the authors investigated the six replacement ratio of tailing to sand from 0% to 50% and developed a single nozzle printing system.
Journal ArticleDOI
Mechanical anisotropy of aligned fiber reinforced composite for extrusion-based 3D printing
TL;DR: In this article, an optimal basalt fiber content was determined basing firstly on suitable printability and then on mechanical performance using a self-developed 3D printer for extrusion of the cementitious material and also for mechanical enhancement of fiber alignment along the print direction.
Journal ArticleDOI
Micro-cable reinforced geopolymer composite for extrusion-based 3D printing
TL;DR: In this article, the feasibility of directly entraining a continuous micro steel cable (1.2mm) during filaments (12mm) deposition process, forming a reinforced geopolymer composite material was explored.
Journal ArticleDOI
Mechanical improvement of continuous steel microcable reinforced geopolymer composites for 3D printing subjected to different loading conditions
TL;DR: In this paper, continuous and simultaneous micro-cable reinforcement methods are investigated to accommodate the 3D flexible and automatic characteristics of additive manufacturing processes, and to satisfy the mechanical-property requirements for construction applications.
Journal ArticleDOI
Interlayer reinforcement of 3D printed concrete by the in-process deposition of U-nails
TL;DR: In this article, U-shaped nails are inserted into concrete during the printing process to increase the tensile strength and shear strength of 3D printed concrete, and the bridging effect and dowel action of the applied U-nails are visualized and analyzed to elucidate the toughness improvement.
