Fused Deposition Modeling (FDM)

Definition

Fused Deposition Modeling (FDM) is a 3D printing technology that creates objects by melting and extruding thermoplastic filament through a heated nozzle, layer by layer, to build up the desired shape. This process allows for the precise control of material placement, making it a popular choice for prototyping and production of complex geometries. FDM is particularly relevant in additive manufacturing, as it enables the incorporation of biomimetic designs that mimic natural forms and functions, promoting innovation and efficiency in product development.
