FDM (Fused Deposition Modeling) uses a heated nozzle to melt and extrude thermoplastic filament layer by layer according to 3D CAD data. Each layer quickly cools and bonds with the previous layer to build the final part.

FDM is an economical and practical 3D printing process with a wide range of material options. It is ideal for large parts, durable functional components, and customized parts for specialized applications.
