What Is FDM 3D Printing?
FDM works by feeding a thermoplastic filament through a heated nozzle, melting it, and depositing it in precise paths across the build platform. Each layer fuses to the one below it as it cools, building the part from the bottom up. Support structures are added where needed and removed after printing. The result is a solid, durable part ready for functional testing, assembly, and real-world use — straight off the machine with minimal post-processing.
