Far from being a process or just a trend, additive manufacturing is more of a technological revolution that comes under the fourth industrial revolution. As the name suggests, the additive manufacturing process works by adding materials. Layers upon layers of materials are deposited successively on top of each other until the desired object is produced. What is additive manufacturing? Additive manufacturing (AM) is the industrial manufacturing process that uses computer-aided-design (CAD) software or 3D object scanners to direct hardware to deposit material, layer upon layer, to create desired geometric shapes. How does additive manufacturing work? The very first step in additive manufacturing is to create a 3D model of the object. This model can be designed using computer-aided design (CAD) software. This CAD file is now converted to a standard additive manufacturing file format, which is usually an STL file. The STL file is then digitally sliced into different layers. The third sta
