​NTU Singapore cements 3D printing research with sustainable fly ash geopolymer

Published on: 05-Sep-2017

​The team from the Nanyang Technological University (NTU) has an exciting new innovation - a geopolymer cement made of waste fly ash particles. Fly ash, a by-product of the coal combustion process, is produced in large amounts each year. Recycling fly ash to make geopolymer cement significantly reduces carbon footprint of traditional cement production process, and reinforces the material with superior heat-resistant properties.

In a recent study from the Singapore Centre for 3D Printing at NTU, the limitations to the current process of 3D printing for construction and the possibilities for the multi-material printing of buildings are explored. A full study of the research discussed in this article is available online in the Journal of Cleaner Production, August 2017. It is co-authored by Biranchi Panda, Suvash Chandra Paul, Lim Jian Hui, Yi Wei Daniel Tay, and Ming Jen Tan.
