【Crazy 600mm/s Printing Speed】 : Combining a nimble Core XY with a 190g lightweight printhead, K1 max 3D printers ramps up to 600mm/s in only 0.03s with 20000mm/s2 acceleration. It is 12 times faster than a regular 3D printer. The speed is bolstered by the powerful dual-core CPU and the latest self-developed slicer Creality Print. It can be as productive as several 3D printers together. 【32mm³/s Flow & Dual Cooling】: A new ceramic heater encircling the hotend can melt various filaments instantly. The dual-gear direct drive extruder and titanium alloy heatbreak ensure 32mm³/s full-blast feeding flow in up to 300℃. The freshly printed model is cooled rapidly by two fans, one on the printhead with directional air ducts, and another in the build chamber. The model hardens before any stringing.
