Design and manufacture of high-performance 3D printed sustainable building composites using cellulose nanomaterials

Principal investigator: Mehdi Khanzadeh Moradllo

University: Temple University

Industry partner: TAKTL LLC

This study aims to build a partnership between Temple University and TAKTL LLC to transform the architectural façade industry in Pennsylvania by introducing an innovative manufacturing process and novel sustainable products. The integration of 3D printing as a construction technology to the current industry is under rapid development due to faster construction, efficient usage of materials, and optimized shape and topology. However, key challenges exist to deliver cost-effective and sustainable 3D printed cementitious mixtures.

The overall objective of this study is to develop high-performance 3D printed sustainable cementitious composites using cellulose nano (CN) materials and alternative cementitious materials for architectural applications. CN-materials are “green” nanoparticles that can improve the mechanical properties of cement- based materials. This proposal will design the formulation for the production of CN-based architectural elements to enhance mixtures' extrudability, buildability, and hardened properties. This project will utilize state-of-the-art experiments to characterize the dimensional stability, mechanical performance, and durability of 3D printed composites. The techno-economic feasibility of the commercial application of 3D printed composites will be evaluated. The life-cycle assessment analysis will provide an overall reduction in the environmental impacts of the CN-based composites. This project will take the application of 3D printing in the architectural façade industry from the “research topic” to a market-ready process.
