bottom-up manufacturing

Bottom-up manufacturing is a process where complex products are built by assembling smaller components or building blocks, rather than starting with a finished object and working backward. It focuses on creating precise, tiny parts first—such as nanomaterials or micro-scale components—and then integrating them to form a larger, functional device or structure. This approach allows for high precision and customization, often used in advanced fields like nanotechnology and microelectronics, enabling the production of innovative, miniaturized systems. It contrasts with top-down methods, which begin with a bulk material and shape it into the final product.
