Bottom-up approach

Definition

The bottom-up approach is a method of construction and design that starts at the smallest components and builds up to larger structures. This approach emphasizes creating intricate designs at a microscopic level, which can then be assembled into more complex systems. In additive manufacturing, especially within the realm of nanotechnology, this strategy is essential for achieving precise control over material properties and functionalities.
