Nano Silica Particles as A Structural Build Up Agent for 3D Printing Cement Paste with Additional Accelerators

Abstract. 3D printing also commonly known Additive manufacturing (AM) is the layering of materials by a computer to build 3D shapes of desired materials. It's very handy for prototyping and working with geometrically complicated materials. It was founded and developed in the 1980s, but it was a costly and demanding procedure at the time, with few uses. It became quiet relevant and inexpensive in the 2000 and a variety of applications which includes product development, component manufacturing, and tool manufacturing, plastic, aerospace engineering metalworking, Foot wear, dental and medical applications, and electronics. Even the household uses of 3D printers were happening. The construction sector also started using 3D technology and the systems used were called 3D printers for construction Computer-aided design, or CAD design, or the usage of a 3D scanner are both used to build a 3D model.
