Fabrication is a research area that involves the creation of physical objects or structures through various techniques and processes such as cutting, shaping, assembling, and joining materials. This can include traditional methods such as machining, welding, and casting, as well as advanced techniques like 3D printing, nanofabrication, and microfabrication. Fabrication is an important field in engineering, materials science, and other disciplines as it allows for the production of complex and specialized components and devices that serve a wide range of applications in industry, healthcare, consumer products, and more.
