Fused filament fabrication (FFF/FDM)
F2 · Intermediate
This printer is positioned in the intermediate tier due to its massive build volume (420x420x480 mm), making it suitable for large-scale prototypes or small batch productions. It integrates native Klipper firmware, allowing high-speed printing up to 500 mm/s, and a high-temperature nozzle (300 °C) capable of handling a wide variety of thermoplastic materials. Despite its high performance, the open structure and Cartesian kinematics require a certain degree of maintenance and expertise to achieve optimal prints, as well as a very large workspace to accommodate the movement of the heated bed.

Software
The system relies on an open ecosystem thanks to the motherboard with pre-installed Klipper. Users can manage the machine both through the 4.3-inch capacitive touchscreen interface and via local network using the integrated web interface (Fluidd). Elegoo provides its own customized version of the Cura slicer, but the printer remains fully compatible with most third-party slicers such as PrusaSlicer, OrcaSlicer, and Simplify3D. Native support for Wi-Fi and LAN connectivity facilitates sending and monitoring G-code files without the need for physical media.
Reviews from those who use this machine every day will be available in the next version of the platform.
