Precision FDM printing enhances standard FDM through finer nozzles (0.2–0.3 mm), reduced layer thickness (down to 50 µm), and optimized print parameters (temperature, print speed, retraction). The result is tighter tolerances, smoother surface finishes, and improved dimensional accuracy—suitable for detailed prototypes, small mechanical parts, and applications where higher resolution ... https://xcmachining.com/fused-deposition-modeling-fdm/
