3D PRINTING OF FOAMED CONCRETE

Global Journal of Science & Engineering, 2020
This paper discusses the needs for 3D printing in comparison to conventional construction and proposes foamed concrete material for printing. Example of 3D printing projects under study to overcome housing crisis are presented. Stability and sufficient strength and structural integrity are the main parameters to look for when looking of printable ...

Influence of Geometric Design on Mechanical Performance of Auxetic Metastructure

Advanced Engineering Materials, EarlyView.
Strategic geometric reinforcement transforms auxetic performance. This study evaluates 3D‐printed arrowhead metastructures, revealing that a modified design with local ring reinforcement suppresses premature failure to achieve superior energy absorption and structural efficiency.

Designing a Habitat for 3D Concrete Printing in Permafrost Regions

Joelho, 2023
3D concrete printing has the potential to provide solutions to the global shortage of affordable housing. The technology may be particularly suitable for remote regions, where the shortage of labor and materials present challenges.

Compatibility of Methacrylate Based Resins Controls Interfacial Failure and Toughness in 3D‐Printed Multimaterial Composites

Advanced Engineering Materials, EarlyView.
This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...

Incorporating coarse aggregates into 3D concrete printing from mixture design and process control to structural behaviours and practical applications: a review

Virtual and Physical Prototyping
Three-dimensional concrete printing (3DCP) is progressing from lab pilots to large-scale manufacturing, encountering limitations with conventional printable material  – cement mortar. Coarse aggregate concrete (CAC) emerges as a promising alternative due

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.
