Fused Deposition Modeling
Fused Deposition Modeling (FDM) is an additive manufacturing (3D printing) process that creates objects by extruding thermoplastic material layer by layer through a heated nozzle. It is widely used for rapid prototyping, functional parts, and low-volume production due to its simplicity, affordability, and material versatility. The technology works by melting a filament (e.g., PLA, ABS) and depositing it along a predefined path to build up the 3D model.
Developers should learn FDM when working in hardware prototyping, product design, or engineering fields that require physical models, custom parts, or iterative testing. It is particularly useful for creating functional prototypes, jigs and fixtures, and end-use parts in industries like automotive, aerospace, and consumer goods, as it allows for quick design validation and cost-effective small-batch production.
