Engineers value FDM for its affordability, ease of use, and compatibility with materials such as PLA, ABS, PETG, and specialized composites. The technology produces functional prototypes and end-use parts with excellent strength and durability.

Compared to other 3D printing technologies, FDM typically delivers a lower surface quality and less detailed resolution. Because the process builds parts layer by layer, material properties can vary depending on the direction of applied forces.

Fused Deposition Modeling (FDM) uses an additive manufacturing process that heats thermoplastic filament to its melting point and extrudes it through a nozzle. The nozzle or build platform moves along defined axes while depositing material, creating the part layer by layer from a digital 3D model.

Many FDM systems support multi-material printing through multiple nozzles, allowing manufacturers to combine different materials within a single build. The process also enables custom infill patterns that increase strength while reducing weight, material consumption, and cost.
