3D printing is defined as the process of creating 3 dimensional structures, layer by layer. It is an additive manufacturing technology which is widely known. 3D printing was first introduced in 1987 and has been growing steadily over the years [1]. As technology advances, more materials, such as concrete, steel and plastic, can now be used for 3D printing. As the world is leaning towards automation and digitalisation, manual fabrication might be replaced by robots so as to maximise efficiency, as well as to reduce cost in the long run. 3D printing is still a relatively new technology in our society. Hence in order to maximise the capabilities of the printing process, admixtures needs to be studied in detail. Our group hopes that through research and testing, we would be able to create the most viable cement paste for large scale industrial manufacturing. Also, the properties of the material is constantly changing with time. Thus, we took note of the time whereby the properties of the material is the most suitable for printing. Hence, increasing the strength of the printed structure.
