K1 Max FDM 3D Printer.4.3 Color LCD Screen.Automatic Leveling.Flexible Build Plate Bed.300 x 300 x 300mm Print Size.K1 Max reaches 600mm/s in only 0.03s based on 20000mm/s² acceleration. It can be as productive as several 3D printers together. K1 Max combines the nimble Core XY with a 190g lightweight printhead for less motion inertia. Agile and swift. New ceramic heater, encircling the entire hotend. It heats to 200? in 40s and melts the filament instantly. Dual-gear direct extruder, delivering strong extrusion force. Hotend with a titanium alloy heatbreak and a hardened steel nozzle, working with flying colors in up to 300 Degrees. A large fan on the printhead with air ducts cools the model directly. An 18W auxiliary fan in the build chamber enhances the cooling effect, too. The model hardens before any stringing and warping could happen. It allows support-free bridges and overhangs. The latest self-developed slicer Creality Print 4.3 includes rich presets, and streamlines the slicing process into 3 simple stages. Even better, it bolsters high-speed printing with variable line width, arc path, and so on. K1 Max boasts a 300x300x300mm large build volume, great for rapid prototyping or design verification. It also offers a high build volume to printer size ratio of 25.5%. K1 Max is the most size-efficient FDM 3D printer in its class.
