3D-printable materials containing construction and demolition waste: a review

Industrial Plasticine for Sustainable and Reusable Iterative 3D Prototyping: Implications for Reducing Material Waste

Iterative 3D printing has become a core practice in product design, enabling rapid cycles of form refinement, dimensional correction, and usability testing. However, despite its efficiency, the process generates large volumes of short-lived polymer prototypes that are rarely recycled, contributing to a growing waste pr...

Self-compacting geopolymer concrete for 3D concrete printing: rheological requirements, mix design challenges, and future prospects

Plastic waste-based construction composites: a review of composition, processing, performance, and environmental impacts

Plastic waste represents a critical global environmental challenge due to its persistence, high production rates, and limited recycling. Construction materials, particularly bricks and blocks, offer a promising avenue for plastic valorization owing to their large material demand and tolerance for heterogeneous feedst...

CONSTRUCTION AND DEMOLITION WASTE FINE AGGREGATE FOR SUSTAINABLE 3D PRINTABLE CONCRETE: RHEOLOGICAL AND MECHANICAL PERFORMANCE

This study investigates the feasibility of incorporating locally sourced construction and demolition waste (CDW) as fine aggregate replacements in 3D concrete printing (3DCP) mixes. Three mortar mixes were developed: a 100% natural sand reference mix, and two recycled mixes replacing natural sand with processed CDW at...

Three-Dimensional Concrete Printing in the Construction Industry: Landscape, Challenges, and Future Opportunities

The adoption of three-dimensional concrete printing (3DCP) has been transforming the construction industry, offering unique design flexibility and efficiency that conventional methods struggle to match. Despite its potential, a critical lack of research exists for nonmaterial categories, including management, cost es...

DEVELOPMENT OF ROBOTIC LIGHTWEIGHT CONCRETE 3D PRINTING FOR MODULAR CONSTRUCTION

Modular 3D manufacturing using cement-based materials, often known as 3D concrete printing (3DCP), is transforming contemporary construction by allowing formwork-less, automated production straight from digital design files. In contrast to traditional casting that needs labor-heavy molds and considerable material wasta...
