3D Printing High-Volume Ash Mixtures for Construction

In the recently published ‘3D printing of high-volume fly ash mixtures for digital concrete construction,’ Nanyang Technological University thesis student Biranchi Panda explores how fly ash-based geopolymers can be improved upon and used in 3D printing in construction.

Concrete is one of the most widely used materials in the world, and contractors have a range of options to choose from today from materials that are fiber-reinforced, made with polymer, and even self-compacting.There are many benefits available with the use of SCC, including flowability, surface quality, durability, and more.

Fabrication of complex geometries, however, is still challenging, requiring added expense and the need for more manpower.3D printing is not only getting attention from industrial users in the construction industry, but it is also quickly gaining traction as a faster, more affordable, and more versatile technology over convention methods.
