Layer-by-layer fabrication

Definition

Layer-by-layer fabrication is a process used in additive manufacturing where materials are deposited in successive layers to create a three-dimensional object. This method allows for the production of complex geometries and detailed features that would be difficult or impossible to achieve with traditional manufacturing techniques. The ability to build objects layer by layer not only enhances design freedom but also supports various applications across different industries.
